ABSORBENT SOLUTION CONTAINING A BREAKDOWN INHIBITOR DERIVED FROM THIAZOLE OR FROM OXAZOLE AND ABSORPTION PROCESS FOR ACID COMPOUNDS CONTAINED IN A GASEOUS EFFLUENT

摘要

The degradation of an absorbent solution comprising organic compounds provided with an amine function in aqueous solution is reduced considerably in the presence of a small amount of degradation inhibiting additives whose structure comprises a 5-atom heterocycle composed of a nitrogen atom, a sulfur atom or an oxygen atom, and 3 carbon atoms, at least one of which is joined to a sulfur atom not belonging to the ring. The absorbent solution is employed for deacidifying a gaseous effluent.
