Abstract

Sulphur oxides are generated from a liquid stream of hydrogen sulphide by feeding the liquid stream to a vacuum stripper where the stream is contacted with a stripping gas including steam under reduce pressure. Hydrogen sulphide is transferred to the stripping gas, whereby a loaded stripping gas is obtained. Water in the loaded stripping gas is condensed producing a H2S rich stream. The H2S is then burned in the stream to produce a stream rich in oxides of sulphur.
