Abstract

Apparatus for a process using supercritical fluid includes a pressure vessel including an agitator for mixing a batch of materials therein; a source of process media supplied to the pressure vessel in a supercritical state; first delivery devices for introducing into the pressure vessel batch materials that are mixed in the presence of the process media in a supercritical state to produce a reaction mixture based on a selectable reaction process; a receiver vessel; and second delivery devices for controlling transfer of the reaction mixture to the receiver vessel; the source comprising a tank for holding a selectable mass of the process media in a supercritical state and for supplying the process media on demand during the reaction process and during delivery of the reaction mixture to the receiver vessel.
