Abstract
Procédé d'épuration de gaz d'évacuation faibles en dioxyde de soufre, ou bien en dioxyde de soufre et en hydrogène sulfuré, comprenant l'absorption du gaz d'évacuation dans une solution contenant du sulfure en l'addition à la solution d'un agent qui provoque la décomposition des éventuels composés de soufre et d'oxygène instables, tels que les thiosulfate et polythionates, qui sont formés dans la solution d'épuration, en soufre élémentaire et sulfate, le pH de la solution sortant de l'autoclave étant ajusté dans la gamme de 2,0 - 2,9.
