Abstract

The present invention relates to a novel aqueous-phase oxidizer and solids separator reactor. More particularly, the invention relates to a two zone pressure vessel in which precipitates and other solids fall or are sprayed from a supercritical temperature super zone into a lower temperature sub zone. The feed material may consist of various waste products which are subsequently oxidized in the super zone of the pressure vessel. The resultant brine or slurry which is found at the lower temperature sub zone of the vessel is removed via a pipe and disposed of accordingly.
