Abstract

Procédé amélioré de traitement de courants gazeux (de gaz naturel en particulier) contenant de l'hydrogène sulfuré, du CO¿2?, de la vapeur d'eau et du méthane. Le procédé repose sur l'utilisation de deux types de membranes dont l'une présente vis à vis de l'hydrogène sulfuré/méthane une sélectivité d'au moins environ 40, mesurée sous pression élevée dans un mélange de plusieurs gaz. Il est possible de mettre au point des procédés optimisés de séparation en jouant sur les différentes propriétés de perméation des deux types de membranes. La séparation à membrane est combinée à un traitement sans membrane des courants de perméats et de résidus.
