Supercritical CO2 Cleaning
Supercritical CO2 cleaning replaces solvents (e.g., CFCs, carbon tet, trichlor, etc.) The trick is to recover energy during pressurization/depressurization. A DOE-funded demo is going in at a foundry in Portland, OR, and a transportable demonstration unit for parts cleaning is on the road, traveling to trade shows. No licensee as yet.
