Click to ViewSupercritical Fluid Extraction is the process of separating one component of choice from the solid matrix using supercritical fluids as the extracting solvent. Carbon dioxide (CO2) is the most used supercritical fluid, sometimes modified by co-solvents such as ethanol or methanol. Carbon dioxide, above its critical temperature (31oC) and critical pressure (74 bar) behaves as supercritical fluid and is used for extraction of the desired component. The solvent strength of supercritical fluid can be manipulated by changing pressure (P) and/or temperature (T); therefore, it may achieve a remarkably high selectivity. For extraction purpose ground solid sample is placed into the extractor vessel and supercritical CO2 is supplied to the extractor through a high pressure pump (100-700 bar). The extract laden CO2 is sent to a separator (60-120 bar) via a pressure reduction valve. At reduced temperature and pressure conditions the extract precipitates out in the separator. The extract free CO2 stream leaving the separator is released to the atmosphere.
