Abstract

A process is described for the separation of solutes dissolved in a gaseous solvent The process is useful in the extraction and recovery of solutes using supercritical fluid extraction, and in the purification of impure steam. The process utilizes a sorbent to remove solute followed by an in situ regeneration of the sorbent and the recovery of the solute.
