Title
(EN) ABSORBENT SOLUTION CONTAINING A SULPHUR-CONTAINING DEGRADATION INHIBITOR DERIVED FROM AN AMINO ACID AND METHOD FOR LIMITING THE DEGRADATION OF AN ABSORBENT SOLUTION
(FR) SOLUTION ABSORBANTE CONTENANT UN INHIBITEUR DE DÉGRADATION SOUFRÉ DÉRIVÉ D'UN ACIDE AMINÉ ET MÉTHODE POUR LIMITER LA DÉGRADATION D'UNE SOLUTION ABSORBANTE.
Abstract
(EN)
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 quantity of sulphur-containing degradation-inhibiting agents derived from an amino acid, defined by the general formula: (I). The absorbent solution is used 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'agents inhibiteurs de dégradation soufrés dérivés d'un acide aminé, définis par la formule générale : (I) La solution absorbante est mise en oeuvre pour désacidifier un effluent gazeux.
