Abstract
A process of separating materials is disclosed which comprises contacting a solid material with a fluid at an elevated pressure within a defined space, forming a fluid mixture of said fluid and a component of the solid material at the elevated pressure, separating the fluid mixture from the insoluble portion of the solid material at the elevated pressure and discharging the fluid mixture, as a mass, from a defined space, while simultaneously reducing the volume of the defined space at a rate sufficient to maintain the elevated pressure during the discharge step. Optionally, the insoluble portion of the solid material may be compacted during the separation step. The solid material may be selected from animal, vegetable, and mineral sources and the fluid may be selected from CO.sub.2 and other gases or liquids. Apparatus for carrying out the process is also disclosed.
