Abstract
In a supercritical oxidation process, the oxidized supercritical fluid effluent (46) discharged from the upper region of the reactor vessel (10) is contacted with a cold quench liquid (66) so as to produce a relatively solids free vapor stream (53) and a liquid stream (51) containing the bulk of the precipitates and other solids carried over in the oxidized supercritical fluid effluent (46). The temperature of the resultant liquid stream (51) is maintained at a temperature below the solids solubility inversion temperature, typically below 600.degree. F., so as to dissolve a substantial portion of the precipitates and other solids collected therein.
