The invention relates to a method and an arrangement for the removal of concentrated odorous gases of a pulp mill. According to the method, the concentrated odorous gases containing sulphur compounds are collected from the odorous gases of the sulphite pulp mill and combusted with under air to oxidize the sulphur compounds, so that at least an essential part of the sulphur compounds is oxidized into elemental sulphur. The elemental sulphur is recovered in a liquid or solid form. It can be returned to the process or used in other processes.

La présente invention a trait à un procédé et à un agencement pour l'élimination de gaz malodorants concentrés d'une usine de pâte à papier. Selon le procédé, les gaz malodorants concentrés contenant des composés soufrés sont recueillis à partir des gaz malodorants de l'usine de pâte au bisulfite et brûlés dans l'air en vue de l'oxydation des composés soufrés, de sorte qu'au moins une partie substantielle des composés soufrés soient oxydés en soufre élémentaire. Le soufre élémentaire est récupéré en forme liquide ou solide. Il peut être recyclé vers le processus ou vers d'autres processus.
