Patent ID: 7507391

Claim:
A process for the production of sulphur oxides from a liquid stream comprising hydrogen sulphide, comprising the steps of: feeding said liquid stream to a vacuum stripper; contacting said liquid stream in said stripper under reduced pressure with a stripping gas, which stripping gas comprises steam that is generated in said stripper, whereby at least part of said hydrogen sulphide is transferred to said stripping gas, whereby a loaded stripping gas is obtained; subjecting said loaded stripping gas from said vacuum stripper to a step wherein water is condensed, thus producing a H 2 S rich stream; and burning H 2 S in said H 2 S rich stream, thus producing a stream rich in oxides of sulphur wherein said process forms part of a wastewater treatment process; of a process for the production of fermentation products; or of a Claus process.
