    Abstract: A process for removing contaminants, including hydrogen sulphide, from a gas stream, comprising the steps of subjecting the gas stream to a Claus Process; subjecting the tail gas obtained in said Claus Process to a SCOT process; recycling the hydrogen sulphide-enriched gas obtained in said SCOT process to the gas stream for the Claus Porcess; subjecting a sulphur-containing residual hydrocarbon product to oxidation to obtain a gas stream which comprises sulphur dioxide; cooling and quenching said gas stream which comprises sulphur dioxide; absorbing said sulphur dioxide with an absorption solvent to obtain a sulphur dioxide-enriched absorption solvent which is regenerated and the sulphur dioxide - enriched gas stream produced therein is used as sulphur dioxide source for Claus Process.

    Abstract: A gas to be desulphurized is contacted with a catalyst containing a catalytic phase associated with a silicon carbide carrier in order to conduct a sulphur-forming reaction between H2S and SO2, and, optionally, a reaction that hydrolyses the COS and CS2 compounds into H2S, at temperatures which, in accordance with the selected implementation method, may be higher or lower than the dew point of the sulphur formed in the reaction gases. The invention is useful for recovering as sulphur H2S and SO2 compounds contained in gases from various sources, such as Claus process gases, and for hydrolysing to H2S the COS and CS2 compounds that the gases may contain.
