Supercritical Fluid Extraction, of solids, is generally operated in batch mode on milled materials (or pellets, granulates), with food grade carbon dioxide as solvent. The equipment consists of two or more extractors operating above the CO 2 critical pressure, and two separators where the extract and the CO 2 are separated prior to the CO 2 being recycled.

Abstract. Since the late 1980s, ,supercritical fluid extraction, (SFE) instrumentation has evolved from a chemical engineering research tool into large-scale commercial applications (e.g. the ,extraction, of caffeine from coffee beans) and finally into the analytical laboratory as an efficient preparation method for a wide range of chemical compounds from a variety of samples.
