Abstract

The process uses >=1 fluid, e.g. a gas on a liq. The pressure is pref. increased slowly followed by a rapid fall. The successive phases pref. pass through maxima increasing from one phase to the next. Pref. >=1 fluid acts physically on >=1 of the constituents. Also >=1 fluid may act chemically on >=1 of the constituents. The process uses strick temp. control avoiding degradation of the material which can occur in solvent extraction and also avoiding the possibility of contamination of the extracts.
