摘要

Process for the treatment of a gas containing at least of the sulfurated hydrogen (h2 s) and at least of the sulphur dioxide (so2) in which it is brought into contact with a suitable temperature, the said gas with an organic solvent containing at least one catalyst is recovered in a gaseous effluent containing essentially of hydrogen sulphide and sulphur dioxide, sulphur, the liquid separated from the solvent by a decantation liquid - liquid. The method comprises the following characteristics * a layer comprising under - products is situated between the sulphur - liquid and the solvent is separated, * is removed at the level of said layer, a liquid fraction (f) containing at least under - solid products, and * it sends the liquid fraction f to a processing step separate from the step of placing in contact, at the end of which is recovered at least one flow f1 comprising the majority of the products under - and a flow f2 composed essentially of a solvent which is practically free of products in -
