ENVIRONMENTALLY SAFE PROCESS FOR DISPOSING OF TOXIC INORGANIC CN-CONTAINING SLUDGE (D# 76,075-F) ABSTRACT OF THE DISCLOSURE Toxic inorganic CN-containing sludge as produced by treating at least a portion of the water used to quench cool and/or scrub the hot raw effluent gas stream from a partial oxidation gasifier with a ferrous salt and a base may be disposed of by separating the inorganic CN-containing sludge from the water and introducing the sludge into the partial oxidation gas generator in admixture with the hydrocarbonaceous fuel feed. Most of the cyanides are effectively destroyed in the reaction zone, and the ash components in the waste solids are recovered as slag from the generator. The separated water is upgraded by further treatment and recycled to the quench tank and/or gas scrubber. The subject process provides an environmentally safe solution for the otherwise costly problem of disposing of toxic sludge. When coal is included in the feed to the gas generator, any calcium in the sludge will act as a fluxing agent for the coal ash. A more fluid slag having a lower ash-fusion temperature is obtained. Because the partial oxidation gasifier may be run at a lower temperature while still producing molten slag, oxygen requirements may be reduced. ptn627 -I-
