Absorbent solution containing a degradation inhibitor derived from a triazole or from a tetrazole and process for the absorption of acid compounds contained in a gaseous effluent

摘要

The degradation of an absorbent solution comprising organic compounds provided with an amino functional group in aqueous solution is substantially reduced in the presence of a small amount of degradation-inhibiting agents belonging to the family of derivatives of triazoles or of a tetrazole, at least one substituent of which contains a sulphur atom. The absorbent solution is used to deacidify a gaseous effluent.
