Title
(EN) METHODS AND COMPOSITIONS FOR SCRUBBING CHLORINE-CONTAINING GASES
(FR) PROCÉDÉS ET COMPOSITIONS D'ÉPURATION DE GAZ CONTENANT DU CHLORE
Abstract
(EN)
Methods and compositions are described that remove chlorine from a chlorine-containing gas stream. The method includes adding a carbonate salt and optionally a scale inhibitor to a scrubbing liquid in a wet scrubbing system, and contacting the chlorine-containing gas with the scrubbing liquid. The amount of carbonate salt that is added can vary depending on the pH of the scrubbing liquid.
(FR)
L'invention concerne des procédés et des compositions qui éliminent le chlore d'un flux de gaz contenant du chlore. Le procédé comprend l'ajout d'un sel de carbonate et éventuellement d'un inhibiteur de tartre à un liquide de lavage dans un système de lavage humide, et la mise en contact du gaz contenant du chlore avec le liquide d'épuration. La quantité de sel de carbonate qui est ajoutée peut varier en fonction du pH du liquide d'épuration.
