METHOD FOR MINIMIZING HYDROGEN HALIDE CORROSION IN A PARTIALOXIDATION PROCESS

摘要

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.
