Inorganic Membranes
INEL has developed a line of inorganic polymer membranes called polyphosphazenes, based on nitrogen and phosphorus rather than carbon, which have better chemical resistance and can operate at higher temperature than organic polymer membranes. These materials have a very versatile chemistry and can be customized for a wide range of applications, such as dehydrating organic liquids, recovering textile dyes from alcohol solutions, and possibly separating SO2 from N2, CO2 from methane, or H2S from methane.
