  • Method and device for processing a gas containing hydrogen sulfide and sulfur dioxide comprising a stage of removal of by-products
    Publication number: 20010055549
    Abstract: A method for processing a gas containing at least hydrogen sulfide (H2S) and at least sulfur dioxide (SO2), includes the steps of contacting the gas with a liquid solvent containing at least one catalyst in a contacting stage, recovering gaseous effluent substantially containing no hydrogen sulfide and no sulfur dioxide from the contacting stage, and separating liquid sulfur from liquid solvent in a decantation zone downstream of the contacting stage. In order to remove by-products resulting from degradation of the catalyst, a liquid fraction F containing at least solvent, catalyst, sulfur and the solid by-products resulting from degradation of the catalyst is extracted from after the contacting stage.
