Patent

CA 2597556

The invention is directed to a process and apparatus for the removal of hydrogen sulphides from streams containing them, in particular from wastewater streams. According to the invention, hydrogen sulphide is stripped from the process liquid by means of a vacuum stripper. The gas thus produced has a high H2S content, which facilitates further processing.

La présente invention concerne un procédé et un appareillage d'élimination de sulfures d'hydrogène de courants qui en contiennent, en particulier de courants d'eaux usées. Selon l'invention, le sulfure d'hydrogène est éliminé du liquide considéré par un procédé sous vide. Le gaz obtenu présente une teneur élevée en H2S, ce qui facilite les transformations ultérieures.
