Abstract

Procédé permettant d'éliminer par électrolyse le dioxyde de soufre (SO2) contenu dans un flux de gaz de combustion et de récupérer les valeurs soufre sous forme d'acide sulfurique. Les sources dudit flux de gaz de combustion contiennent des gaz résiduaires de décharpage de fumée ou d'évacuation provenant de centrales électriques, d'installations d'acide sulfurique, de fours de grillage de minerais et d'incinérateurs de déchets solides. Le but de ce procédé est de réduire les frais de fonctionnement, d'obtenir un sous-produit utile, et de minimiser la pollution de l'environnement. Le procédé électrolytique est réalisé dans une colonne (10) comportant une zone d'épuration contenant un matériau de garnissage (20a) qui sert également d'anode (20). La zone d'épuration contient aussi une cathode (30) qui est isolée (35) du matériau de garnissage mais est en contact intime avec le flux d'acide aqueux.
