Detoxification of cyanides and cyanide-containing solutions

摘要

The method comprises preheating a cyanide solution to be detoxified by passing the cyanide solution through a heat exchanger and initiating a detoxifying hydrolysis of the cyanide solution by subjecting the cyanide solution to a temperature shock raising the temperature of the cyanide solution to between about 200° and 250° C and passing the cyanide solution through a tubular reactor at a pressure of between about 40 and 140 atm.
