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 and of liquid sulfur separated from the solvent by a decantation liquid - liquide.au the course of the process, it is drawn off from the reactor - contactor a monophase solution comprising at least of the solvent, the catalyst, sulfur and under - products, and it sends the said solution to a processing step, comprising at least one step of heating of the solution at a temperature which is suitable for promoting the crystallization of the products under - and at least one step of separation of the products under - solvent. It is then recovered at least one fluid f1 composed essentially of solvent, catalyst and of sulfur and practically free from under - products, and a fluid f2 comprising the majority of the products under -
