ABSTRACT:
Apparatus and methods for reducing residual solvent levels in extracted biomass that is contaminated with HFC solvent that includes sparging the biomass extract with a solvent stripping gas such as air or nitrogen are disclosed. Apparatus for carrying out the method include a vessel (12;25) containing extract (26) and a source of the gas. The source may be in the form of a moveable, hollow wand (27) having a sparging gas outlet; or a fixed gas inlet (30) for bubbling the gas through the extract (26).
