Supercritical Fluid Extraction of Oil from Freshwater Edible Crab (Barytelphusa Cunicularis).

摘要

ABSTRACT In the present study Supercritical Fluid Extraction (SFE) method is used in order to extract oil from Freshwater Edible Crab (Barytelphusa Cunicularis). Carbon dioxide gas is used as a supercritical fluid and Hexane is used as a modifier. Extraction is performed at different temperatures (25o C to 45o C) and pressures (10 Mpa to 30 Mpa). Oil is extracted at constant flow rates. The flow rate of carbon dioxide gas is kept constant 1 ml/min and flow rate of modifier (Hexane) is also kept .
