Supercritical Fluid (SCF) Technologies: Assessment of Applicability to Installation Restoration Processes.

摘要

USAEC has conducted an evaluation of Supercritical Fluid (SCF) technologies for their applicability to treatment of explosives, chlorinated hydrocarbons, and metals in soils, water, and/or waste sludge media. Off-specification explosives and propellants that have traditionally been open burned or openly detonated were also examined. Supercritical fluids are substances which have been heated and compressed to above their critical temperatures and pressures and possessing unique transport and mass transfer properties. Supercritical fluid extraction (SFE) used the solvating properties of supercritical fluids to extract one or more organic components from a mixture into a supercritical solvent (commonly CO2). The concentrated extract stream may then be recycled, reclaimed, or destroyed by other methods.
