ABSTRACT:
A process for the removal of trace quantities of hydrocarbonaceous compounds from an aqueous stream which comprises the steps of: (a) contacting a solvent, which in the supercritical state is effective to dissolve the hydrocarbonaceous compounds from the aqueous stream, with the aqueous stream, for a time sufficient at supercritical solvent conditions to dissolve at least a portion of the hydrocarbonaceous compounds and to produce an aqueous stream having a reduced hydrocarbonaceous compound concentration; (b) separating the hydrocarbonaceous compounds from the solvent at subcritical conditions; and (c) recovering the hydrocarbonaceous compounds.
