HYDROGEN CYANIDE DESTRUCTION

摘要

A method of eliminating hydrogen cyanide, particularly hydrogen cyanide present in foul gas streams, is achieved by reacting hydrogen cyanide with hydrogen sulfide and oxygen to produce ammonia and carbon sulfides. A preferred embodiment destroys the hydrogen cyanide present in foul acid gas streams recovered from industrial gas desulfurizers, and the process is particularly useful when employed prior to a Claus or similar sulfur recovery unit. the process can also be used to produce commercial quantities of carbon disulfide.
