a system and method for oxidizing a feed material includes a reactor vessel that forms an enclosed chamber . the vessel includes a port for introducing the feed material into the chamber where it can be oxidized to create salts and particulates , together with a fluid effluent . after their creation , the salts and particulates flow into a brine pool maintained within the chamber . thereafter , brine , including salts and particulates , can be removed from the chamber through a vessel outlet . further , the vessel includes a fluid effluent discharge pipe extending from outside the vessel , through the brine pool , into the chamber . as a result of this structure , the fluid effluent can be separated from the salts and particulates and discharged from the chamber through the pipe , passing through the brine pool .
