Title (EN) ABSORBING SOLUTION CONTAINING A DEGRADATION INHIBITOR DERIVED FROM PYRIDINE, AND METHOD FOR ABSORBING ACIDIC COMPOUNDS CONTAINED IN A GASEOUS EFFLUENT
(FR) SOLUTION ABSORBANTE CONTENANT UN INHIBITEUR DE DEGRADATION DERIVE DE LA PYRIDINE ET PROCEDE D'ABSORPTION DE COMPOSES ACIDES CONTENUS DANS UN EFFLUENT GAZEUX
Abstract: front page image
(EN)The degradation of an absorbing solution comprising organic compounds having an amine function in an aqueous solution is substantially reduced in the presence of a small quantity of degradation inhibitor additives belonging to the family of pyridine derivatives having at least one substituent that contains a sulfur atom. The absorbing 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'additifs inhibiteurs de dégradation appartenant à la famille des dérivés de la pyridine dont au moins un substituant contient un atome de soufre. La solution absorbante est mise en oeuvre pour désacidifier un effluent gazeux.
