    摘要: 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. The liquid fraction F is sent to a processing stage distinct from the contacting stage where the liquid fraction F is heated to a temperature at least partially crystallizing the by-products, and the at least partially crystallized by-products separated from the rest of the liquid fraction F containing at least solvent. At least a stream F1 comprising solvent, catalyst and sulfur and substantially free of the by-products and a stream F2 mostly comprising the by-products are recovered.

In order to remove by-products, such as sulfate and thiosulfate salts, 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 the contacting stage and sent to a processing stage distinct from the contacting stage where the liquid fraction F is heated to a temperature sufficient to at least partially crystallize the by-products, and the crystallized by-products are separated from the rest of the liquid fraction F containing at least solvent. At least a stream F1 comprising solvent, catalyst and sulfur and substantially free of the by-products and a stream F2 mostly comprising the by-products are recovered.

    摘要: The natural gas arriving through pipe 1 is deacidified by being brought into contact with a solvent in zone C. The solvent charged with acid compounds is regenerated in zone R. The acid gases, released into pipe 5 upon regeneration, include a quantity of solvent. The method enables the solvent contained in the acid gases to be extracted. In zone ZA, the acid gases are brought into contact with a non-aqueous ionic liquid whose general formula is Q+ A−, where Q+ designates an ammonium, phosphonium, and/or sulfonium cation, and A− designates an anion able to form a liquid salt. The solvent is removed from the acid gases evacuated through pipe 6. The ionic liquid charged with solvent is regenerated by heating in an evaporator DE. The ionic liquid regenerated is recycled through pipes 8 and 9 to zone ZA. The solvent is evacuated through pipe 13.

    摘要: The gaseous feed flowing in through line 1 is contacted in contacting zone ZA with a liquid solvent flowing in through line 2. The solvent comprises between 0.001% and 100% by weight of a liquid olefin. Contacting in zone ZA is carried out in the presence of an acid catalyst. The purified gaseous feed is discharged from zone ZA through line 3. The sulfide-laden solvent is discharged through line 4, then regenerated in unit RE. The regenerated solvent is recycled through lines 7 and 2 to zone ZA.
