摘要： Installation for membrane permeation treatment of feed gas flow containing at least methane and carbon dioxide including first, second, and third membrane separation units and at least one compressor B for aspirating the second permeate, a permeate from the first membrane separation unit being fed to the third membrane separation unit, a retentate from the first membrane separation unit being fed to the second membrane separation. After measuring the aspiration pressure and methane concentration of the second permeate before it is recycled to the feed, the pressure of the second permeate is adjusted according to the measured aspiration pressure and methane concentration.
