Membrane gas separation plant and method for operating same

A method is proposed for operating a plant for purifying a high-pressure gas mixture from easily permeating components, which plant comprises membrane gas separating units having a high-pressure chamber and a low-pressure chamber with a selectively permeable membrane therebetween, in which method th...

description	A method is proposed for operating a plant for purifying a high-pressure gas mixture from easily permeating components, which plant comprises membrane gas separating units having a high-pressure chamber and a low-pressure chamber with a selectively permeable membrane therebetween, in which method the low-pressure chamber of at least one membrane gas separating unit is continuously flushed with purified gas mixture (semi-finished product or product), wherein the pressure difference between the aforementioned chambers of the membrane gas separating unit and, likewise, the flow rate of the purified gas mixture used for flushing are maintained so that the amount of each easily permeating component in the product does not exceed the desired values. The proposed method makes it possible to purify a raw material (high-pressure gas mixture) from one or more easily permeating components simultaneously (in particular helium, hydrogen sulphide, mercaptans, carbon dioxide, water and/or heavy hydrocarbons), increase purif
