ABSTRACT:
A supercritical water oxidation reactor is described having first and second reaction zones connected in series and through which an aqueous feed stream to be oxidized can be passed in either direction. A self-contained heat exchange fluid system allows supercritical and subcritical temperatures to be maintained in either reaction zone. When supercritical water oxidation is occuring in one reaction zone the effluent is being cooled to a subcritical temperature and used to flush the second reaction zone to remove inorganic scale.
