ABSTRACT:
An extraction vessel A is charged with a particulate solid, e.g. oilseed, and a transfer liquid, e.g. water, in an amount sufficient to pressurize vessel A to an elevated pressure. Extraction solvent, e.g. carbon dioxide, is introduced, preferably from a storage vessel B, to displace transfer liquid from vessel A. After extraction by the solvent, the latter may be displaced into vessel B by transfer liquid which is preferably stored under pressure in vessel B during the extraction.
The extraction solvent is gaseous at ambient conditions but preferably is liquid or a supercritical fluid at the displacement conditions.
