Abstract: In order to solve the problem of cyanides contamination in the tail gas of cyanuric chloride production,a three-step treatment technology including methane combustion,ammonia catalysis and water absorption is proposed.Analysis results indicate that cyanogen chloride and chlorine gas in tail gas from cyanuric chloride crystallization proceed firstly REDOX reaction with methane to generate CO2,NOx,H2O and HCl,which further mixes with ammonia and then performs desalination and ammonia catalytic reaction to generate CO2 and N2.Traces of activated carbon remaining in tail gas can be removed by water absorption.The harmless emission is realized finally.
