A method of separating one or more components from a multi-component gas stream (10) comprising at least one non-acid gas component and at least one acid gas component, wherein the multi-component gas stream (10), at a pressure above 1,200 psia (82.8 bar) and a temperature above 120 ~F (48.9 ~C) with a concentration of the at least one acid gas component in gas stream (10) being at least 20 mole percent, is passed to a membrane system (40) that selectively separates the at least one acid gas component from the multi-component gas stream (10) as a permeate stream (13). Permeate stream (13) has a pressure of at least 20 percent of the pressure of the feed pressure.
L'invention concerne un procédé de séparation d'un ou de plusieurs composants d'un courant gazeux (10) à multiples composants, comprenant au moins un composant gazeux non acide et au moins un composant gazeux acide. A une pression supérieure à 1200 psia (82,8 bar) et à une température supérieure à 120 ·F (48,9 ·C), et avec un pourcentage molaire de concentration dudit composant gazeux acide dans le courant gazeux (10) d'au moins 20 pour cent, le courant gazeux (10) à composants multiples passe dans un système membranaire (40) séparant de manière sélective le composant acide du courant gazeux (10) à multiples composants de façon à obtenir un courant (13) de perméation. La pression du courant (13) de perméation représente 20 pour cent de la pression d'alimentation.
