Supercritical fluids (SCFs) are ncreasingly replacing the organic solvents that are used in industrial purification and recrystallization operations because of regulatory and environmental pressures on hydrocarbon and ozone-depleting emissions.SCF-based processes have helped to eliminate the use of hexane and methylene chloride as solvents.With increasing scrutiny of solvent residues in pharmaceuticals,medical products,and neutraceuticals,and with stricter regulations on VOC and ODC emissions,the use of SCFs is rapidly proliferating in all industrial sectors.Supercritical fluid extraction (SFE) plants are operating at throughputs of 100,000,000 lbs/yr or more in the foods industry.
