Abstract:
A process for utilization and extraneous component removal treatment of a supercritical fluid composition without gasification, wherein said process is conducted while maintaining said supercritical fluid composition in a supercritical or a pressurized liquid state, comprising(a) utilizing the supercritical fluid (SCF) composition in an SCF-using process system; (b) removing the supercritical fluid composition from the SCF-using process system, wherein the supercritical fluid composition contains at least one extraneous component in respect of further disposition of said supercritical fluid composition; (c) converting the supercritical fluid composition to a pressurized liquid; and (d) treating the pressurized liquid to at least partially remove said at least one extraneous component therefrom, thereby preparing it for said further disposition.
