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 hydrogen halide-containing synthesis gas, finely divided particulate solids, and a nontoxic slag. The hydrogen halide-containing synthesis gas is contacted with water in the quench zone (14) of the gasifier (10). The quench water contains a neutralizing agent, in excess of the amount necessary to neutralize hydrogen halide acids present therein, to thereby form halide salts. The quench water containing the halide salts is purified to recover the halide salts. The salt-free water is essentially environmentally non-toxic and can either be recycled to the process or discarded in conformity with environmental regulations. |
