Overview & Organization
Technologies & Programs
This report is proprietary and confidential. It is for internal
use by personnel of companies that are subscribers in the UFTO multi-client
program. It is not to be otherwise copied or distributed except as
authorized in writing.
This report details findings about technology and technology transfer
opportunities at the Argonne National Laboratory that might be of strategic
interest to electric utilities. It is a major update and revision
to materials developed previously, and is based on a visit to the lab in
July 1998. It also draws from various publications, collateral information
and website content.
Argonne National Laboratory (ANL) is a "GOCO" lab (government-owned,
contractor operated). It is managed by the University of Chicago.
It was started in 1946 with the express purpose to develop peaceful uses
for nuclear power. The current annual budget is approximately $470
M, and there are 4500 employees. About 20% of the funding is "work
for others", which includes government agencies other than DOE, and private
industry. Since 1990, more than half of the projects with industry
have been with small businesses.
Similar to other DOE labs, ANL has a matrix organizational structure of "Divisions" and "Programs." The divisions are aligned by programmatic area, and have the people, projects and budgets. Programs are mainly to coordinate the Laboratory's efforts across divisions. In a few instances, programs take on a larger role; e.g., in the case of fuel cells.
Both divisions and programs live in research "ALD's" or Associate Laboratory Directorates, headed by Assoc. Lab Directors who along with other administrative and support groups report to the Laboratory Director.
Argonne's four research ALD's are:
- Physical Research (basic research in fundamental sciences)
- Advanced Photon Source (a new high-energy X-ray facility for basic research)
- Engineering Research (mostly advanced nuclear and national security)
- Energy & Environmental Science & Technology (EEST)
Of these, virtually all work of potential interest to utilities is in EEST. However, much of the work in EEST programs is carried out by cross-ALD, cross-divisional teams. For example, the work of the Electrochemical Technology Program involves major participation by staff from the Chemical Technology Division of the Engineering Research ALD.
ANL has a number of "User Facilities" and "Centers" that focus on particular subjects, and make special equipment, facilities and expertise available to outside users, on a fee or collaborative basis. These are housed within programs and divisions.
The Advanced Photon Source is a major new facility that has just begun
operations recently. About 30 private companies use its unique capabilities
to examine the structure of materials (metals, alloys, proteins, catalysts,
etc.) and to watch the dynamics of chemical processes at time scales of
a billionth of a second.
EEST itself has a number of the divisions and programs, four of which are grouped together as:

monitor and fault detection system (MSET)
Sensor monitor and fault detection system knows if the system is misbehaving or the sensor is wrong. Can see slow drift, signal dropout, and noise, giving early indicators of sensor failure, and providing assurance that the process itself is operating normally, thus reducing unneeded shutdowns. It also can monitor the process itself, for wide ranging quality control applications.
MSET stands for Multivariate State Estimation Technique. A model learns expected relationships among dozens or hundreds of sensor inputs, and makes predictions for what each sensor should say, and this is compared with the actual sensor signal. Argonne has patented a unique statistical test for residual error (the difference) which replaces the usual setting of fixed limit levels. There are also important innovations in the system modeling algorithm, which is completely non-parametric. (Argonne's patented modelling algorithm is vastly superior to neural nets, achieving 1-2 orders of magnitude higher accuracy and in a tiny fraction of the computation time.) This extremely sensitive system detects the smallest developing faults at the earliest possible time and alerts plant personnel, substantially enhancing system safety, availability and operating efficiency for a wide range of applications in utilities, aerospace, industrial and other settings. An 1998 R&D 100 Award winner.
Applications have ranged from the NASA shuttle engine, to several power
plants, to the stock market.

On-Line Plant Transient
PRODIAG monitors thermal-hydraulic processes and identifies faulty components, such as clogged filters and pipe breaks, in real time during off-normal process operating conditions. Intended originally for diagnosing off-normal process conditions in nuclear power plants, PRODIAG has a wide range of process-industry application. PRODIAG is an 1998 R&D 100 Award winner.
PRODIAG's diagnostic system continuously receives process data -- such as fluid temperature, pressure, flow and level -- from the plant and identifies components whose failure has caused the off-normal plant condition -- for example, a leak in this heat exchanger, a clogged filter in that piping, or the inadvertent opening of a particular valve.
Uses thermal-hydraulic first principles, along with generic equipment
data, in a two-level knowledge system. Generic, qualitative first-principle
expert system rules of the system can rapidly indicate what's causing a
transient, e.g. water loss, heat added, etc., and identify where in the
system the problem lies. The system wouldn't need to be custom built
for each plant, except to incorporate the plant's schematics. It's
been validated through blind tests with a nuclear plant's operator training
simulator data. Next step is to hook it up to a full scale simulator, and
then go for NRC approval. A fossil application would be much easier.

Steam Generator Tubing Diagnostics
Eddy Current (EC) Non Destructive Evaluation (NDE) techniques can detect the presence of small defects, but can't characterize them well, in particular to predict a tube's structural integrity and burst pressure. EC signal interpretation is difficult, and past attempts to correlate signal features with burst pressure have shown only limited promise. Argonne is developing a new class of model based on "artificial neural nets". Using knowledge of tube fracture mechanisms, they select certain features of the signals to train and test the model. Early results show significant improvement in predicting burst pressure for the limited data that is available. The technique is being tried on other data sets, including data from Argonne's own Leak/Burst Pressure test facility, where actual tubes are tested to failure.
Contact: Tom Wei, 630-252-4688, firstname.lastname@example.org
Leak Rate Test Facility
Steam Generator tubes can be tested operating pressures and temperatures, and also under design-basis accident conditions, up to and including leakage and burst.
In support of the NRC Steam Generator Tube Integrity Program, the facility
obtains data on burst pressures, failure modes, and leak rates of flawed
tubing at temperatures up to 343°C (650°F), pressures of 21 MPa
(3000 psi), and pressurized-water flow rates up to 760 L/min (200 gal/min).
The important features of the facility are a large blowdown-vessel water
inventory to ensure high, stable flow rates and permit full-range testing
of initially stable leaking cracks to instability; piping and valves of
a size appropriate to minimize pressure drop in the supply line to a flawed
tube and thereby permit high flow rates; the use of a downstream back-pressure
regulator valve to control tube secondary-side pressure, thereby minimizing
nonprototypical two-phase flow from entering the tube; and a computer feedback
valve control to allow programmed ramps of the pressure differential across
the tube. The tubes tested in the facility have either laboratory-grown
cracks produced by chemical means or machined flaws. Both axial and circumferentially
oriented flaws are examined. Crack sizes range from very small cracks,
which are stable under main steam line break (MSLB) conditions, to larger
cracks, which will first propagate through the wall and then eventually
grow unstable as the pressure is increased to that corresponding to MSLB.

Advanced NOx Control with Gas Co-firing
Neural network based controller adjusts furnace control variables to get optimal distribution of gas injection to yield greatest NOx reduction. Typical systems use gas at 20% of heat input, to obtain up to 60% NOx reduction. This system uses gas at 7% of heat input to achieve up to 45% NOx reduction. Joint effort with ComEd, GRI, and Energy Systems Assoc.

Surface Condensers Improve Heat Rate
A long-established method to reduce the heat rate is to lower the back-pressure of the surface condenser. This is accomplished by retubing existing units with commercially available enhanced tube, Korodense LPD, made by Wolverine Tube, Inc.. TVA is the only utility to implement this on a widespread basis, and has had very good success for the past 15 years. The rest of the industry, however, has been very slow to consider or adopt it, though virtually every other type of heat exchanger uses surface enhancement (including many other power plant systems).
If the turbine is operating near the choked condition, backpressure reductions won't improve performance, then it may not be worth doing. In many cases, however, payback can be as short as 1 to 3 years. Seasonal benefits can be significant, i.e. in the Summer, when both water temperature and demand are high.
Argonne has done analyses to 1. determine the potential heat-rate reductions that are possible by retubing with enhanced tubes; 2. make utilities aware of these benefits; and 3. eliminate such technical concerns as tube-side fouling, tube vibrations, and in-situ nondistructive tube inspections.
Argonne has written a computer program to calculate the heat-rate reduction obtained by retubing with enhanced tube. The program incorporates the thermal performance data obtained by monitoring 14 operating TVA condensers that were retubed. Although it is a research grade code, it has been and can be made available to interested parties.
All the major barriers to the use of enhanced condenser tubes have been
eliminated: uncertainty of performance, concern of excessive fouling,
and lack of long-term successful demonstrations. However, each potential
application must be analyzed to evaluate the cost effectiveness.
Increases of 30-40 in the overall heat-transfer coefficient are obtained in the clean condition with Korodense LPD. Argonne continues to monitor the performance of these units and others to update these characteristics. For most river waters, the superior performance is maintained for a year or more after a cleaning by any of the usual methods. Intermittent chlorination also effectively controls biofouling. The 14 retubed TVA condensers are operating successfully, one of them for 18 years.
Penn State has developed good prediction techniques for newer tube types, and there is progress in identifying superior tube configurations for each potential application. If a host utility can be identified, it would be possible to demonstrate these performance improvements by conducting experiments with one of the company's condensers.

Argonne is involved in a number of programs applying superconductors to electric power systems:
- Superconducting Transmission Line - with SouthWire, a SC cable between the utility and one of SouthWire's own plants. Argonne is doing the cryogenics, dielectrics and power electronics.
- Fault-current limiters act as nonlinear resistors and reactors and have diverse applications in electric power systems. With S&C Electric (Schweitzer & Conrad), Argonne investigated a HTSC resistive fault-current limiter design, and patented it and licensed it to Illinois Superconductor Corp. In a separate effort with S&C, they have also investigated several inductive-limiter designs in which the HTSC is used to magnetically shield a ferromagnetic material. Several small-scale models of this type of limiter have been demonstrated. It should be noted these designs use bulk superconductor, not wire.
- A cryostat current lead that conducts electrical power from room-temperature sources to devices operating at liquid helium temperatures. Working with Babcoc& Wilcox on a HTSC lead for a large SMES device, Argonne specified a design that has been adopted by several companies and resulted in an IR-100 award for American Superconductor. In a separate project with Superconductivity Inc. (SI) (now ASC), Argonne provided the material for a prototype lead that was tested at SI.
- SC bearings for the flywheel system under development at Argonne with funding from Com Ed. (See separate discussion.) In addition, there is a new DOE-funded flywheel project with Boeing that also uses HTSC bearings.

The Millimeter-Wave Laboratory at Argonne is doing R&D on gas-phase spectroscopy and nondestructive testing (NDT) of materials. For remote sensing of effluent and thermal signatures, Argonne is also developing a multichannel passive mm-wave radiometer system. In collaboration with Clean Air Engineering and two Russian institutes, they're developing a mm and submm gas analyzer for real-time analysis of industrial pollutant gases. In the NDT area, Argonne has developed a unique mm-wave imaging system in the W-band (75-110 GHz range) for detection and imaging of flaws in low-loss materials such as plastics, ceramics, and composite materials. As a practical extension of this work, Argonne has developed a compact near-field imaging sensor for on-line inspection and control of process materials. Argonne received a 1996 R&D 100 Award for the on-loom millimeter wave fabric inspection system.

A new carbon film many times slicker than Teflon reduces friction by up to 100 times and wear by up to 1,000 times below the levels achieved with conventional low-friction materials in a dry N2 test environment. Near-Frictionless Carbon films make rolling, sliding, and rotating machine parts operate more efficiently and last longer. The coating is also hard enough to show promise as a coating for automotive parts subjected to sliding friction and wear. An 1998 R&D 100 Award winner.
The new material's coefficient of friction is less than .001 when measured in a dry nitrogen atmosphere -- 20 times lower than the previous record holder, molybdenum disulfide. When tested under the same conditions, Teflon's coefficient of friction is around .04 and steel's is about 1.1.
The material's wear resistance is tested in a machine that slides a sapphire ball in a circle on the coating's surface under high pressure: one gigaPascal, about 145,000 p.s.i. or almost 10,000 times atmospheric pressure. In one test, the new material lost just one micron (four ten-thousandths of an inch) in thickness after five million cycles. The test left a barely visible ring on the material's surface.
The material is produced in an "rf plasma chamber" which converts a proprietary gas containing carbon into plasma. Carbon and other elements drift down from the plasma onto a substrate, usually a polished disk of sapphire or steel, where they form the coating. The material has no crystalline structure. Argonne is still researching the material's composition and formation process.
Compared to previous methods of producing carbon coatings, the new process is quick -- it takes only a few hours -- and can produce large amounts of the coating. The non-toxic material adheres well to many kinds of substrates, including plastics.
There is a great deal of interest from many directions, particularly in automotive and refrigeration, for application to seals (shaft, rotary, reciprocating, sliding, etc.). A brochure is available.

Ice Slurry District Cooling
UFTO reported on this back in 93/94. It is now privately funded, and has advanced considerably. Ice slush dramatically increases the capacity of new or retrofitted central cooling distribution systems.
Argonne, under U.S. DOE funding, pioneered the development and fostering of ice slurries for district cooling. Because of the high energy content of ice slurries, which is due to the phase-change (i.e., melting) of the ice particles at a cooling load, the energy content of a slurry pumped to a load can be up to five times greater than that associated with chilled water delivered at the same mass flow rate. This high energy content also allows slurry transmission piping and storage tank sizes to be reduced significantly over what would be required with conventional, chilled-water cooling systems. Today both domestic and foreign interests have considered adopting this technology for the cooling of large loads.
The storage of ice slush in tanks, however, is complicated because under certain not well understood conditions, the ice crystals will progressively grow together, or agglomerate, making pumping of the slurry from the tank very difficult. It is desirable to store the slurry at the highest packing density possible, in order to most effectively utilize the available tank size. Therefore, even if the ice does not agglomerate in the tank, it must be carefully diluted to a packing density that is compatible with pumping it through a pipe delivery network. No reliable means has been developed for tank-slurry extraction or ice-loading control.
A research project, initiated in July 1997 in collaboration with NKK
Corporation of Japan, is being conducted in the reconfigured Argonne Slurry
Test Facility and is performing experimental studies on the factors influencing
ice crystal agglomeration in ice slurry storage tanks. The studies will
also address developing methods for minimizing agglomeration and for improving
the efficiency and controllability of tank extraction of slurry for distribution
to cooling loads. These studies will address the remaining engineering
issues for utilization of the ice slurry cooling concept. Argonne
is seeking additional participants in it's program both the laboratory
development and a field slurry demonstration.

GASMAP -- Analysis and Tracking Tool for the Natural Gas Industry
**User Access is available on request, on a collegial basis.** The limitation is server capacity, so ANL is not in a position to throw it wide open. They are also very open to any companies that want to provide better data on their own gas T&D systems--which can be kept confidential.
(Taken from ANL webpage: http://www.dis.anl.gov/disweb/gasmaptt)
GASMAP, a comprehensive geographic information system (GIS), contains information never before gathered in one place and organizes it for use by professionals in the industry. Data include:
--All the government data forms collected by DOE including FERC and
EIA, integrated in a common format and linked together
--Spatial data on natural gas pipelines and their respective points
--Energy-related data about cogeneration units, electric utility plants, service territories of local distribution companies (LDCs), and natural gas storage fields
Users can locate map data on more than 100 interstate pipelines, information on more than 2,000 companies and more than 1,000 variables.
GASMAP contains many layers of graphic data. This map identifies and locates 100 interstate pipelines. GASMAP integrates three commercial applications and links them through a custom graphical interface. MapInfo serves as the GIS component, Microsoft FoxPro is the relational database engine, and Microsoft Visual Basic supplies the menu system and interface. The system is PC-based and uses Windows.
Professionals use GASMAP's analytical and tracking capability to assess
pipeline capacity and deal with routing and location issues. They can also
extract sales, customer, system flow, and storage data on utility companies.
With simple menu selections, users can:
--Produce maps displaying specific pipelines or pipelines layered with other energy data and supporting background information (e.g., roads, streams, railroads)
--Produce tables and graphs
--Review data by company, state, or topic and compare them with related data
A data dictionary links all the forms and information into index files. The user can view all data for a specific state or company without knowing the files or variables being used. The menus guide the user through the query, address it, and provide results in either tabular or graphical form.

Ceramicrete Phosphate Ceramic
Argonne has developed this low-cost, ceramic binder which can be used in a wide variety of commercial applications, ranging from hazardous waste disposal to low-cost insulation. 1996 R&D 100 Award. Called CERAMICRETE, the binder -- developed to stabilize and solidify radioactive and hazardous wastes -- can also join ceramics together and convert nonhazardous wastes into useful construction products and nonflammable structural materials. It is formed by mixing magnesium oxide powder and soluble phosphate powder (common low cost materials) with water.
It is particularly applicable to fly-ash, because it is completely insensitive to the pH level, and it immobilizes virtually any type of contaminant, including mercury and other heavy metals. It forms a nonporous leach-resistant, hard, and dense ceramic which lab tests indicate meet or pass the EPA TCLP leaching standards.
CERAMICRETE can be manufactured at a low cost compared to other ceramic binders because it is made at room temperature and does not need high-temperature treatment. The setting times are short. Equipment needed is conventional (much like for cement) and hence is readily available, and training required for operations is simple.
The final material can be cast in any shape, and is very dense and strong. It can be used as a structural material in buildings, roads or other structures, or as brick, blocks, or tiles. It has compressive strength ranging from 2000 psi with binder to 6-8000 psi and even more with binder plus additives. In fact, the materials properties can be tailored, with strength increased by compaction during formation.
Besides solidifying wastes, the process can be used to convert lumber wastes into non-flammable particle board or to recycle waste plastic into blowable insulation that is fire- and moisture-proof. CERAMICRETE has already been used to make insulation products with thermal resistance (R values) of 4.5 per inch.
Argonne is using the CERAMICRETE process to stabilize low-level radioactive waste, such as soil, sludge, and lead bricks in a 55-gallon drum mixer. Contaminated wastes that contain radioactive contaminants and hazardous volatiles, such as mercury, lead, and cadmium are solidified in the binding process at room temperature to form a ceramic, noncorrosive, and final waste form. The process is unique because contaminants are converted and stabilized chemically into their natural minerals in a single step. Once encapsulated, the chemicals do not dissolve in groundwater and are isolated from the environment. Performance tests show that the waste forms far exceed the regulatory performance criteria set by DOE and the U.S. EPA.

Multi-Fuel, Compact Fuel Processor for Fuel Cells
Steam reforming and partial oxidation reforming are two of the techniques available to convert hydrocarbon fuels (natural gas, gasoline, LPG, methanol, ethanol) into hydrogen. Steam reformers are better developed but have poor transient response capability and are comparatively large. To overcome these limitations, Argonne is developing a catalytic partial oxidation reformer. The device is less than one-half the size of a car's fuel tank, small enough to fit under the hood of a compact car beside a 50-kw PEM fuel cell.
Argonne's reformer combines methanol with oxygen from the air to produce a hydrogen-rich mixture of gases that is injected into the fuel cell. Compared to other reformers, Argonne's is lightweight, compact and energy-efficient. It is also flexible enough to respond well to frequent startups and shutdowns and to the rapidly changing engine demands of daily stop-and-go driving. The design is simple and inexpensive to manufacture. In addition to hydrogen, the reformer produces carbon dioxide and carbon monoxide. A small on-board chemical reactor would convert the carbon monoxide into carbon dioxide.
The device is a cylinder packed with a catalyst. Fuel and water are sprayed onto the top of the catalyst. An ignition source starts the reaction with air. This reaction rapidly heats the fuel/water solution to appropriate temperatures. Variations in power demands can be met easily by changing the feed rates into the reformer, in a manner very similar to that used in today's fuel-injected internal combustion engines.
An engineering-scale reformer has been tested with methanol, using an
inexpensive and commercially available catalyst. Argonne has developed
a new class of catalysts that are capable of converting gasoline, ethanol,
and natural gas. Tests are in progress. Very recently, the engineering
reactor has been operated with gasoline and natural gas.

Advanced Fuel Cells
Argonne is conducting R&D on a solid oxide fuel cell and a molten carbonate fuel cell, both of which are targeted for use as small power plants in utility applications such as hospitals.
For the solid oxide fuel cell, Argonne is developing new electrodes, electrolytes, interconnect materials, and processing techniques to reduce the operating temperature from the present 1000 deg C to 800 deg C, or even lower. At these lower temperatures, manufacturing costs would be reduced, operating efficiency increased, and cell durability improved. They have also developed glass and glass/ceramic materials to seal along the edges of each cell and between the gas supply manifold and fuel cell stack. These sealants are able to seal different cell components and withstand the requisite cell operating temperatures and gas compositions.
In the present molten carbonate fuel cells, the nickel oxide cathodes limit cell lifetime because of cathode dissolution and migration to the nickel anode. Argonne has developed lithium ferrate and lithium cobaltate cathodes that are expected to yield the long cell lifetimes (over 40,000 hours) needed for utility applications.
In addition, advanced cell designs are being developed for higher power
density and lower cost. The power density is being increased through use
of multiple gas manifolding, pressurized operation, and design optimization.
The cost is being reduced through eliminating complex and expensive stamped
metal parts that currently form the gas flow channels, the electrode supports,
and the current collectors for each cell.

Tool: A Dynamic Fuel Cell System Simulation Model
Argonne researchers have developed GCtool, a system design and analysis software for fuel cell and other power plants for automotive and stationary applications. GCtool can be used for steady-state and dynamic analyses of arbitrary system configurations. It uses a C-language interpreter for interfacing precompiled modules (component models) and can handle modules and interconnecting flows of any level of sophistication. The user can establish constraints, conduct parameter sweeps, and perform constrained optimizations. New component models can be written in any C-linkable language (e.g., FORTRAN) and easily added to GCtool.
GCTool's mathematical utilities include a nonlinear equation solver, a constrained nonlinear optimizer, and an integrator for ordinary differential equations. Property codes are provided for gas-phase and multi-phase chemical equilibria, condensable pure substances, and steam/water properties. The component model library includes various types of fuel cells, heat exchangers, fluid devices, reactors (for example, steam and partial-oxidation reformers, water-gas shift reactors, preferential oxidizers for carbon monoxide cleanup, and catalytic burners), and other components, such as electric motors, generators, and controllers for use in vehicle systems.
This software tool has been used for the analysis of a variety of PEM fuel cell systems using different fuels, fuel storage methods, and fuel processing techniques. These include compressed hydrogen systems; hydride, glass microsphere, and sponge-iron hydrogen storage systems; and fuel cell systems with reformers for methanol, natural gas, and gasoline, using partial-oxidation reforming and/or steam reforming.
GCtool has been used to analyze reference pressurized and atmospheric
pressure automotive PEM systems. These analyses include identification
of the key constraints and the important design parameters to meet those
constraints, off-design operation, system dynamics and transient performance,
and the effects of operation in extreme ambient temperature conditions.
In the dynamic mode, GCtool has been used to analyze system start-up from
cold and warm conditions, as well as to determine system performance and
efficiency during ramp-up and ramp-down transients. GCtool is being enhanced
to incorporate component weight, volume, and packaging calculations, as
well as component and system cost functionalities.

of Fuel Cells
The Fuel Cell Test Facility at Argonne National Laboratory provides independent testing to evaluate and validate fuel cell technologies. Through standardized tests and test conditions, Argonne provides its sponsors with comparative data on the performance, operational characteristics, and durability of fuel cells. The test results also help developers and sponsors evaluate technical progress. When appropriate, post-test analysis can identify sources of performance limitations.
For stacks and systems up to 50 kW, the equipment allows control of
the temperature, pressure, humidity, and flow rate of both the fuel and
air supplies. The effect of these operating parameters on performance
can be quantified under various power profiles. The fuel can be either
pure hydrogen or simulated reformate (the output gas of a reformer, a device
to produce hydrogen from other fuels). The effectiveness of water
management systems can also be monitored and evaluated. Future testing
is expected to include the evaluation of integrated fuel cell systems,
including fuel reformers, compressor/expanders, and energy storage devices.

Information Architecture System (DIAS)
Contact: Craig Swietlik, 630-252-8912, email@example.com
DIAS is a flexible, easily expandable information framework in which new or existing ("legacy") software models and applications can operate harmoniously and synergistically. Such applications may include simulation models, database access and data discovery engines, analytical tools, and display software of various types (and languages). The DIAS software is fully object based, supported by a true object database, and can be run in a fully distributed fashion. DIAS incorporates an advanced object-based geographic information system (which is also Web enabled) for spatial data manipulation and display. DIAS implements an expert-system-guided protocol for coupling software applications by allowing them to selectively link to an object based representation of the problem. The applications to be linked, as well as the details of the linkages and data flows, are determined automatically at run-time, based on the context of the simulation or analysis. The context is represented by user-supplied goals and constraints. The DIAS architecture supports an unprecedented degree of flexibility and ease of use for complex, multidisciplinary analyses. Argonne has delivered DIAS-based software systems to numerous sponsors since 1993.
An external graphical user interface (GUI) is used to input the commands that describe the "context" of the simulation as well as to display the results. DIAS accommodates a wide variety of data types and formats. For example, it can accept terrain elevation and surface features in NIMA-, USGS-, and TIGER- supported formats; interpreted remote sensing imagery; CAD-type data of 3-D objects; weather data in World Meteorological Organization formats; and data from most commercial off-the-shelf (COTS) database management systems. The GUI system uses a GeoViewer module that can display results spatially at user-selectable levels of resolution. The GeoViewer also can manipulate, query, and analyze the displayed data.
DIAS provides easy integration of both new and legacy-type models or
objects and application tools (in their original language). It allows
the easy use of COTS programs to provide scientific visualization and business
graphics capability. If proprietary data file structures can be interpreted,
DIAS can also link with products such as Arc Info and ERDAS. (To
integrate a model or application, a "registration" process is employed.
Once a model or application has been "registered", it can interact, if
the context is appropriate, with any DIAS simulation.) See
additional details at:
As an example, DIAS may provide the framework for linking various models
for electric production analysis. These models may include weather
predictions for a specific region, load forecasting algorithms to anticipate
electric load requirements for the next day, maps to show the locations
of utility power plants within the region, and optimization algorithms
to examine the trade-offs between purchasing power from various local utilities.
This type of application illustrates the complex information interchange
requirements involved in linking models so that the feedback mechanisms
are adequately represented.
Mesoscale Weather Modelling
The Dynamic Environmental Effects Model (DEEM), the first well-developed application using DIAS, has been used by the USAF Air Weather Service as the software framework for a multidisciplinary environmental modeling effort in support of theater-level mesoscale weather forecasting. It has also been used by the South Florida Water Management District as its framework for an advanced hydrological modeling system; by Forces Command to incorporate environmental impacts into mobilization estimates; and by DoD OSD to simulate environmental effects for the Joint Warfare Simulation Program.
The weather modeling work done by Argonne also includes the porting of the National Center for Atmospheric Research MM-5 mesoscale model from a Cray to an IBM SP-2 parallel computer. The parallelization of this model involved detailed analysis of the computational structure and processing inherent in the model and subsequent restructuring to optimize the code in a parallel machine environment. Along with this work, advanced data visualization tools were developed to interpret the results from the weather models and display the data over a map of the particular region.
Parallel processing technology is particularly applicable to large-scale computer codes, which typically have long execution times and yet are sufficiently modular that they can be restructured for processing in a parallel environment.
Facility Profile Information Management System (FPIMS)
The FPIMS for Environmental Site Data is a comprehensive repository that stores hundreds of documents for more than 80 DOE facilities, such as Baseline compliance assessments, National Environmental Policy Act (NEPA) reports, Environmental audits, Environmental impact statements, Guidance manuals, and Site maps. FPIMS provides researchers with the information to: conduct policy, trend, and other analyses; gather information for decision making; and respond to Freedom of Information requests
FPIMS, a fully automated search-and-retrieval information system, organizes information like an electronic library. A highly graphical interface allows users to locate information by using a location map and bookcases organized by category, with lower-level selections on bookshelves and individual documents. Searches are simplified through the use of key words and phrases, prioritized selections, and comprehensive hyperlinks.
FPIMS is World Wide Web-based and fully automated. It is one of Argonne's "Live Systems," at http://search.dis.anl.gov
Argonne applies advanced text retrieval display tools, search aids,
and analysis tools which provide context for information, and which go
beyond commercially offered solutions. These digital libraries organize
and structure large information repositories to allow researchers to locate
data rapidly and efficiently without having detailed knowledge of the information
collection. This type of large-scale information system provides
the foundation for a data warehouse, which integrates various types of
data into a single repository. Technical information on various facilities
can be maintained and searched in these on-line text databases, together
with photos, site maps, floor plans, equipment layouts, and multimedia
Materials Information Exchange (HMIX)

Strategic Planning Systems
Strategic planning systems are helpful for allocating research and development budgets, conducting mission planning, selecting computer hardware and software, and siting facilities.
Argonne's systems are based on a logical and systematic approach to decision making that can be used successfully to explain and defend decisions. Systems are customized to deal with the specific problems and issues of a particular customer.
Interactive Decision Analysis (IDEA) -- Analyzes complex problems in an interactive process that involves decision makers. Graphical output illustrates the sensitivity of outcomes to different assumptions regarding uncertainties or value trade-offs.
Portfolio Analysis Support System (PASS) -- A step beyond IDEA in its ability to allocate inadequate budgets among competing requests over a multiyear time horizon.
PASS is an easy-to-use, computer-based decision support system for portfolio analysis. It is designed to help define and analyze strategies for allocating limited budgets among competing projects or program areas. PASS identifies alternatives that best achieve objectives. It examines project sequencing and equity through the use of portfolio constraints.
Resource Allocation Support System (RASS) -- Specially developed for
the Department of Energy's Office of Waste Management to analyze different
ways to allocate an annual multibillion-dollar budget across a variety
of waste operations activities.

Argonne's cost engineering experts have experience in cost and schedule estimating and analysis, benchmarking, facilities characterization, environmental assessment, and value engineering. They use existing cost estimating models and databases and have also developed new analytical and information tools.
Argonne's cost engineering experts support public and private sector customers in estimating and analyzing the cost of large, complex projects that must be implemented over a multiyear time frame. Organizations that have sponsored such projects include the DOE; Department of State; Federal Emergency Management Agency; the Army, Navy, and Air Force; World Bank; and EPRI.
Comparative cost estimates focus on developing and applying a unified methodology that takes into account the total life-cycle costs; start-up costs; recurring costs (operation, maintenance, etc.), and indirect costs (overhead, profit, contingencies, etc.). The results are consistent, accurate, and defensible estimates. Argonne has applied its cost estimating and analysis expertise to projects for the DOE, the Army, Shell Oil, and Gulf Oil.
Argonne's cost engineers often serve as impartial analysts who validate, cross-check, or analyze cost estimates developed by parties involved in a particular project. These reviews are often used before funds are allocated for major projects. This type of review examines the consistency of the assumptions that have been used by those in charge of cost projections and estimates. It also considers the applicability of the cost basis that has been used.
Argonne cost engineers also develop detailed project management plans, in which cost and schedule issues are analyzed in terms of total budget and targeted completion date.
Argonne's approach involves all parties who will be doing the work, and can examine "what if" scenarios for multiple funding options if the financial picture changes.

Argonne environmental scientists have set a new standard for characterizing contaminated waste sites for cleanup. The QuickSiteSM process--an Argonne-developed technology--is the basis for the American Society for Testing and Materials' expedited site characterization standard, which attained provisional status in December 1996.
Argonne's work is the only reference for this new standard. Using the QuickSiteSM process increases the accuracy of site characterization and can reduce costs by up to 90 percent and field time by as much as 95 percent. These savings can greatly accelerate the environmental cleanup programs of government agencies and private industries.
The QuickSiteSM process integrates a number of scientific disciplines and uses analytical techniques that can identify the best sampling locations with a minimum of soil disturbance and monitoring wells. The results are analyzed, interpreted and integrated on site by a full team of scientists using a continually changing work plan.
The technique has been used at the Department of Energy's Pantex Plant
in Texas. DOE estimates that the QuickSiteSM process has saved $4 million
and four years in a remedial program to clean up contaminated groundwater.

Oxygen Enriched Diesels
----- Late Breaking News -----
In a major announcement at Argonne by the Secretary of Energy on September 25, a new technique was revealed that eliminates the NOx problem directly (i.e. without the need for post combustion treatment). By manipulating the O2 level in the combustion air along with parameters of fuel injection, Argonne has found a set of operating conditions in which both particulate and NOx emissions are simultaneously reduced, and power and efficiency increased. Details are protected under a CRADA agreement with an industrial partner, and a patent application has been filed.
Argonne researchers have developed an oxygen enrichment device that reduces particulate emissions almost 60 percent while increasing engine power output. This could be the link that can help diesel engines meet federal standards for particulate and smoke emissions set by the Clean Air Act.
Oxygen enrichment -- increasing the ratio of oxygen to fuel in engine cylinders -- improves combustion. The increased amount of oxygen is fairly small, but the change is dramatic, resulting in a faster burn rate and higher flame temperatures while increasing engine performance 60 percent. The products of incomplete combustion, including such pollutants as hydrocarbons and carbon monoxide, are reduced.
In partnership with Compact Membrane Systems, Argonne is working to develop a low-cost, selectively permeable membrane to separate ambient air into oxygen- and nitrogen-rich streams.
The oxygen-enrichment technology was originally developed to reduce hydrocarbons and carbon monoxide only in the diesel's cold-start phase, when NOx emissions are relatively low. Normally, however, using oxygen-enrichment when the engine is warm maintains the improved engine performance, but increases NOx.
Monotonic Nitrogen -- To solve the NOx problem, the nitrogen produced as a byproduct of the O2 enrichment is sent to the car's exhaust system. There, a spark plug-like device creates a plasma of monatomic nitrogen which bonds with the NOx in the exhaust. The bonding results in O2 and N2 - the basic components of air.
Researchers are also using this technique to reduce emissions from diesel buses and cars powered by gasoline and alternative-fuel. The monatomic nitrogen technique has been shown to reduce nitrogen oxide emissions by 25-30 percent in a gasoline engine. Studies are also being conducted to use a variable oxygen-to-nitrogen ratio for intake air to improve the overall performance and emissions of internal combustion engines.
Argonne's work to improve diesel engine efficiency and emissions spans the range from the smallest diesel engines to locomotives. In a new dedicated engine research facility, Argonne researchers work with such companies as Mercury Marine, Chrysler Corp., Ford Motor Co. and General Motors Co., as well as railroad associations and transit authorities. Research includes building a next-generation diesel locomotive and developing methods to convert conventional bus engines to clean diesels or hybrid diesels.
Argonne evaluated the possibility of applying its oxygen-enrichment
technology or a diesel-electric hybrid system to Chicago Transit Authority
buses. Argonne analyzed the performance and emissions of a typical
urban bus powered by conventional diesel fuel and an optimized diesel-electric
hybrid system, an found that both concepts are practical and could result
in a "clean diesel" bus that meets the mandated limits of the Clean Air

Microwave Recovery of Hydrogen and Sulfur from Refinery Wastes
Each year, the refining industry consumes a quarter-billion dollars of hydrogen in order to remove sulfur from refinery products. This creates more than 6 million tons of hydrogen sulfide, a waste that must be treated to meet environmental regulations. Although current waste-treatment technology recovers nearly all of the sulfur (99.0-99.5), the remaining amount is emitted to the atmosphere as sulfur dioxide. Moreover, the valuable hydrogen is burned to water, making it unavailable for further use. This loss has a direct impact on bottom-line production costs for the refinery.
Argonne is developing a new process, called MISHA, that uses microwave plasma chemistry to split hydrogen sulfide. This patented process recovers hydrogen and sulfur from hydrogen sulfide and recycles the hydrogen to the refinery. MISHA (Microwave-Induced Sulfur and Hydrogen Autolysis) is an excellent fit for refineries because it would replace both the Claus and tail-gas clean-up units while decreasing the need for costly on-site hydrogen production. In some refinery situations, MISHA can also replace the amine purification unit, thereby achieving even greater refinery savings.
Argonne's experiments have confirmed the critical contribution of the cyclonic flow to increasing the hydrogen sulfide conversion and lowering its energy of dissociation. However, the experiments challenge two of the predictions derived from a theoretical plasma-chemical model: (1) Argonne obtained a plasma at atmospheric pressure with less than 1 kW of power, whereas the model predicted that 30 kW or more was required; and (2) the Argonne experiments do not show the predicted sharp rise in dissociation energies at pressures greater than 0.65 atm Ñ this suggests that the process will operate economically above atmospheric pressures. Furthermore, Argonne's analysis of the gas dynamics in the plasma-chemical reactor indicates that additional improvements in hydrogen sulfide conversion and process efficiency are possible.
Experiments show that MISHA recovers both the hydrogen and the sulfur at lower costs while saving energy and oil, MISHA's hydrogen sulfide emissions would be minuscule, less than 10 tons/yr, for a facility recovering 158 long tons/day of sulfur and 3.9 million scf/day of hydrogen, and, in some locations, MISHA could easily be used to recover marketable hydrogen from natural gas production operations.
Argonne is searching for an industrial partner to scale up the laboratory plasma-chemical reactor to an industrial-scale prototype reactor operating with 10-20 kW of microwave power. This plasma reactor would provide the economic data needed to determine the commercial potential of the process and the necessary engineering data to design a commercial process for treating hydrogen sulfide.
This plasma-chemical process could also be used to recover and recycle chlorine from hydrogen chloride waste streams or bromine from hydrogen bromide waste streams with hydrogen being produced as a by-product in both cases.

When ordinary materials are made nano-sized (1 to 10 nanometers), they acquire extraordinary new properties. Nanoparticle catalysts have been reported to be 60 times more active than comparable catalysts prepared by conventional techniques. Argonne has begun developing a process that could allow commodity production of such nano-sized metal and metal-alloy catalysts.
Tiny catalyst particles produced by Argonne's continuous, low-energy process are collected on ceramic supports. These ultra-high-activity catalysts may be as much as 60 times more active than conventionally prepared catalysts.
Harnessing the high activity of nanoparticles for catalytic processes in the chemical and refining industries would be a major breakthrough. Higher activities for known catalysts would improve the yield of plastics and gasoline, improve hydrodesulfurization, and boost the efficiency of hydrocracking (breaking down heavy hydrocarbons to more completely use each barrel of oil). Moreover, less catalyst would be needed for current production levels, so producers could cut their inventories of expensive precious-metal catalysts.
The problem is that current laser systems for making nanocatalysts are feasible only for producing research quantities. However, Argonne's microwave-powered, plasma-chemical process could operate continuously, unlike laser systems, and would require less energy (see "How It Works"). Furthermore, the process produces particles in one step, rather than the several steps required by conventional synthesis routes. These advantages should make it feasible to scale up the microwave process to industrial quantities.
Argonne would like to form a partnership with end users and suppliers of catalysts to develop this process to industrial scale. The new technology has been used to produce microgram quantities of metal particles as small as 6.0 nanometers and metal-alloy particles as small as 1.56 nanometers. These particles are smaller than most other recent nanocatalysts. Gram quantities of catalyst may have been produced, but thus far the rate of capture is low; the immediate technical challenge is to find a method for capturing all the particles produced.
Contact: Chris Marshall, 630-252-4310, firstname.lastname@example.org.
How it works: Argonne's plasma-chemical process for producing nanocatalysts
A nonequilibrium plasma breaks down a precursor compound into its elemental
constituents in a reducing atmosphere. The metal nanoparticles are rapidly
condensed from the vapor phase. Metal alloys are prepared by simply mixing
precursor compounds to give the ratio desired in the catalysts. The nanoparticles
are collected on ceramic monoliths (see photo) or on high-surface-area
supports, such as alumina or zeolite powders. A microwave generator provides
the energy necessary to maintain the plasma and to break down the precursor
compounds. Currently, a hydrocarbon solvent is required to deliver the
precursors. Metal oxide nanoparticles can be produced by changing the process
atmosphere to an oxidizing atmosphere.
Advanced Electrodialysis Separations
Electrodialysis (ED) uses ion exchange membranes and an electrical driving force to separate, concentrate or convert ionic chemical species in aqueous solution. Generally speaking, it is underutilized in the U.S. compared with elsewhere in the world, and its reputation for high cost is no longer deserved, as the technology has improved significantly. In many cases, salts, base or acids from industrial process waste water can be reused if they can be efficiently recovered, and the resulting desalted water is easier to dispose of. Industries that stand to benefit range from chemical and commodities, to textiles, pulp and paper, and pharmaceuticals.
Argonne applies advanced ED separations technologies and integrates with other separations processes to enable such recovery and reuse. New high efficiency membranes make ED practical for desalting and water recycle applications, and more recently developed bipolar water-splitting membranes can convert recovered salts to acid without generating a waste product. (see Patent no. 5645703) Used together, "double ED" is showing promise in the manufacture of lactic and succinic acid--see below.
Chemical Feedstocks are generally synthesized from fossil fuels, but using fermentation, agricultural resources could be used instead. However, these resources are not widely used because of the lack of cost-effective fermentation and separation technologies for manufacturing in high-volume. Argonne is applying ED technologies for purification of fermentation-derived organic acids that have strong market potential.
In collaboration with other national labs and Applied CarboChemicals, Argonne is developing new technologies for succinic acid production from renewable carbohydrates. Fermentation of glucose from corn syrup can produce succinic acid, but it is not economically competitive with the hydrocarbon based process. Argonne is improving fermentation efficiency by using conventional and genetic techniques to develop superior succinic-acid-producing organisms that improve product yield, productivity, and tolerance.
Lactic acid is another fermentation-derived organic acid that has a rapidly growing market, especially for biodegradable polymers, lactate ester solvents, and chemical feedstocks. Recent technologies developed at Argonne can significantly lower the production cost of ethyl lactate, which make it possible to replace millions of pounds of toxic industrial solvents with completely benign environmentally friendly solvents.
Conventional technology for primary purification of these organic acids (lactic and succinic) generates large volumes of calcium sulfate salt waste, which poses a serious waste management problem. In contrast, Argonne's process uses advanced desalting and water-splitting ED technologies to purify the organic acid without producing the salt waste.
The feasibility of ED for primary purification of organic acids has been demonstrated using fermentation broths. Economic analysis shows that this process will reduce the overall production cost compared with conventional methods.

Recovering Zinc from Galvanized Scrap
Half of the steel produced in the United States is derived from remelting scrap. However, zinc-coated scrap from the manufacture of automobiles has doubled in the period between 1985 and 1995. This increase is being echoed in zinc-coated scrap from obsolete autos. Steel- and iron-makers are sensitive to zinc, lead and other coating constituents of sheet-steel scrap charged to their furnaces increasing the cost of environmental compliance. Furnace dusts containing the zinc must be landfilled or recycled at significant cost; wastewaters must be treated for zinc removal before disposal. An economical process is needed to strip and recover the zinc from scrap to prepare it for steelmaking.
When such a process is practiced on 4.5 million tonnes of galvanized scrap per year, the operating cost benefits to the steelmaking industry are estimated to be $140 million per year (compared with using non-scrap sources iron). Environmental compliance costs would be mitigated by about $50 -150 million per year. Foreign exchange could also benefit by some $100 million per year, through reduction in zinc imports.
Through a cost shared program with Metal Recovery Technologies, Inc. (MRTI), Argonne National Laboratory has developed a new technology for converting galvanized steel scrap from stamping plant wastes into clean scrap for steelmaking. With further development, the technology could also process galvanized steel scrap from obsolete automobiles.
The process consists of dissolving the zinc coating from scrap in a hot, caustic solution and recovering the zinc from the solution electrolytically. The zinc-bearing scrap is fed to a rotary reactor containing a 70-90 degree C sodium hydroxide solution. Coating metals (zinc, lead, aluminum) on the surface are leached into the solution. The dezinced scrap exiting the reactor is rinsed in water and recycled to a steel mill or foundry. The electrolyte is pumped to a cell where the zinc is electrolytically removed from solution; the power utilization is about 4 kW-h/kg zinc recovered. The zinc can be sold to refiners for purification and resale.
In May, 1998 MRTI announced an intent to upgrade a dezincing pilot facility in East Chicago, Indiana to commercial production of 110,000 tonne/year of dezinced shredded scrap. A U.S. patent was issued for the dezincing process in July, 1998. Argonne National Laboratory terminated its activity on dezincing in July, 1998.
