<p>A process for removing sulphur-containing contaminants including hydrogen sulphide, from a gas stream, comprising the steps of subjecting the gas stream to an oxidation treatment, extracting heat from the resulting gas stream, reacting catalytically H2 S from said cooled gas stream with sulphur dioxide at elevated temperature to obtain a gas stream which comprises sulphur and water, separating sulphur thereby obtaining a H2 S-lean gas stream, subjecting it to an oxidation treatment, extracting heat from the S02-enriched gas stream obtained therein; subjecting a sulphur-containing residual hydrocarbon product to an oxidation treatment to obtain a gas stream which contains S02, extracting heat from said gas stream which comprises S02, subjecting both streams containing S02 to a quench process, absorbing S02 from the resulting gas stream to obtain a S02-enriched absorption solvent which is regenerated and using the S02-enriched gas stream produced therein as S02 source for Claus Process.</p> |
