2-Stage Fractionating Separators

Accudyne has built supercritical CO2 machines with multiple fractionating separators capable of processing a wide range of co-solvents. The machine below has 2-stage fractionating separators, a counter-current column, full recycle and co-solvent addition capability. The system has an 80 L extraction vessel, two flanged separators with controlled temperature and pressure, and full CO2 recycle. It also includes a CO2 counter current column for liquid-liquid extractions. Extraction conditions are as high as 690 bar (10,000 psi) and 110° C (230° F). Co-solvent additions include alcohol, ethanol, acetone, and ethyl acetate to be used in conjunction with SCCO2.
