Abstract: The present invention relates to a method for minimizing hydrogen halide corrosion in quench gasifier during the non-catalytic partial oxidation reaction of a halogen-containing hydrocarbonaceous feed, to produce a hydrog en halide-containing synthesis gas, finely divided particulate solids, and a nontoxic slag. The hydrogen halide-containing synthesis gas is contacted wit h water in the quench zone (14) of the gasifier (10). The quench water contain s a neutralizing agent, in excess of the amount necessary to neutralize hydrog en halide acids present therein, to thereby form halide salts. The quench water containing the halide salts is purified to recover the halide salts. The sal t- free water is essentially environmentally non-toxic and can either be recycl ed to the process or discarded in conformity with environmental regulations.

Abstract: The invention is a thermocouple installation wherein the thermocouple measures the temperature in a gasification reactor. The thermocouple is installed through the wall of a gasification reactor such that the measuring element is behind a continuous layer of refractory hot face brick. The thermocouple assembly is mounted in a opening made through the gasifier wall, the insulating brick, and optionally a portion of the way through the hotface brick.

Abstract: A process for minimizing evaporator scaling during the recovery of liquids and solids from the aqueous effluent discharged during a partial oxidation gasification, wherein the aqueous effluent contains ammonium chloride (NH4Cl). The aqueous effluent is evaporated to produce a distillate water and a brine having an NH4Cl concentration of about 10 to 60 weight percent. The brine can be further concentrated and ammonium chloride crystals are recovered. The distillate water is recycled to the gasification reaction. No effluent discharges to the environment.

Abstract: A method is disclosed for recovering condensed solidified volatile metals from slag that exits the reactor section of a partial oxidation reactor. In a partial oxidation reactor, condensed solidified volatile metals become adsorbed onto the surface of the slag particles and other particulate matter associated with the gasification reaction, such as ash and soot. These particulate materials are removed and recovered. Finely divided slag particles are separated and contacted with a mineral acid to dissolve the adsorbed condensed volatile metals. An acid liquor is obtained from which the dissolved volatile metals are recovered by electrolysis.
