Title
(EN) ABSORBENT SOLUTION CONTAINING A BREAKDOWN INHIBITOR DERIVED FROM THIAZOLE OR FROM OXAZOLE AND ABSORPTION PROCESS FOR ACID COMPOUNDS CONTAINED IN A GASEOUS EFFLUENT
(FR) SOLUTION ABSORBANTE CONTENANT UN INHIBITEUR DE DÉGRADATION DÉRIVÉ DU THIAZOLE OU DE L'OXAZOLE ET PROCÉDÉ D'ABSORPTION DE COMPOSÉS ACIDES CONTENUS DANS UN EFFLUENT GAZEUX
Abstract
(EN)
The breakdown of an absorbent solution containing organic compounds provided with an amino functional group in an aqueous solution is substantially reduced in the presence of a small quantity of breakdown-inhibiting additives the structure of which includes a 5-atom heterocycle made up of one nitrogen atom, one sulfur atom or one oxygen atom and 3 carbon atoms at least one of which is bonded to a sulfur atom not belonging to the heterocycle. The absorbent solution is implemented to deacidify a gaseous effluent.
(FR)
La dégradation d'une solution absorbante comportant des composés organiques munis d'une fonction aminé en solution aqueuse est sensiblement réduite en présence d'une faible quantité d'additifs inhibiteurs de dégradation dont la structure comporte un hétérocycle à 5 atomes composé d'un atome d'azote, d'un atome de soufre ou d'un atome d'oxygène, et de 3 atomes de carbone dont l'un au moins est relié à un atome de soufre n'appartenant pas au cycle. La solution absorbante est mise en oeuvre pour désacidifier un effluent gazeux.
