Process for removing sulphur-containing contaminants from a gas stream |
| 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. |
