A supercritical fluid(scf) is characterized by physical and thermal properties
that are between those of the pure liquid and gas.the fluid density is a strong function of the temperature and pressure. supercritical fluids are increasingly replacing the organic solvents that are used in industrial purification and recrystallization operations because of regulatory and environment pressure on hydrocarbon and ozone-depleting emission.scf-based process has helped to eliminate the use of hexane and methylene chloride as solvents. supercritical carbondioxide in its supercritical fluid state is when both the temperature and pressure are equal or exceed the critical point . in its supercritical state, carbondioxide has gas like and liquid like qualities,and it is this dual characteristic of scf that provides the ideal conditions for extracting compounds with a high degree of recovery in short period of time.because carbondioxide is non polar,a polar organic co-solvent(or modifier) can be added to the supercritical fluid for processing polar compounds.by controlling the level of pressure / temperature / .supercritical carbondioxide can dissolve a broad range of compounds,both polar and non polar.environmentally friendly supercritical carbondioxide and its associated technologies are being applied in many applications to replace hazardous solvents lower cost, and improve efficiencies some of the applications requiring a scf pump include scf extraction(sfe),supercritical fluid chromatography(sfc) ,catalysis/reaction feed, injection molding and extraction,particle formation,cleaning,electronic chip manufacturing, plastics production,etc.with increasing scrutiny of solvent residues the use of scfs is rapidly proliferating in all industrial sectors. scf-based process has helped to eliminate the use of hexane and methylene chloride as solvents. supercritical co 2 in its supercritical fluid state is when both the temperature and pressure are equal or exceed the critical point of 310c and 73 atm. in its supercritical state, co 2 has both gas like and liquid like qualities,and it is this dual characteristic of scf that provides the ideal conditions for extracting compounds with a high degree of recovery in short period of time.because bo is non polar,a polar organic co-solvent(or modifier) can be added to the supercritical fluid for processing polar compounds.by controlling the level of pressure / temperature / modifier. supercritical bo can dissolve a broad range of compounds,both polar and non polar.environmentally friendly supercritical carbondioxide and its associated technologies are being applied in many applications to replace hazardous solvents lower cost, and improve efficiencies some of the applications requiring a scf pump include scf extraction(sfe),supercritical fluid chromatography(sfc) , catalysis/reaction feed, injection molding and extraction,particle formation,cleaning,electronic chip manufacturing, plastics production,etc.with increasing scrutiny of solvent residues the use of scfs is rapidly proliferating in all industrial sectors.
