摘要
A process for advantageously efficiently treating a sulfureous combustible effluent stream by recovering the sulfur in elemental form comprises a step of combustion of the sulfureous combustible effluent stream with an oxidant gas in excess, and then a step of post-combustion of the effluents from the combustion step with an acidic gas. The stream of the post-combustion effluents, free of chemical compounds that are harmful to the efficacy of the Claus catalysts, is treated in a Claus unit, which performs the recovery of the sulfur in elemental form.
