Abstract

Procedure and device for detoxifying cyanides and solutions containing cyanides, characterized in that the cyanuric solution to be detoxified is fed to a tubular reactor with laminar flow of grafts, preheated by heat exchange, and the hydrolysis reaction is set running by means of a thermal shock at a temperature between 200 to 250ºC, and under a pressure of about 40 to 150 gauge atmospheres.
