Abstract

Les arrangements décrits ci-dessus sont fondées sur une théorie de l'absorption sélective du sulfure d'hydrogène plutôt que du dioxyde de carbone à partir du gaz, en se basant sur le contact à contre-courant entre le gaz et les amines tertiaires ou autres, qui présentent une affinité préférentielle pour le H2S plutôt que le CO2 principalement en raison du taux différentiel de l'absorption de ces deux gaz. Le processus d'absorption sélective renforcée est réalisé en effectuant l'absorption en deux étapes. La première opération consiste à mettre en contact de l'amine pauvre avec du gaz sulfureux qui contient à la fois du H2S et du CO2. L'objet de la première opération est de produire une vapeur de gaz qui réponde à une norme arbitraire de contenu en H2S et en CO2. La seconde opération est d'améliorer la sélectivité du H2S en mettant en contact l'amine riche résultant de la première opération avec un deuxième gaz acide très concentré ayant un rapport H2S/CO2 plus élevé que le premier gaz acide.
