摘要： A method for liquefying ammonia can include the steps of: providing a pressurized carbon dioxide stream from a power generating facility; expanding the pressurized carbon dioxide stream to a lower pressure that is sufficient to produce a dual phase carbon dioxide fluid; introducing the dual phase carbon dioxide fluid to a gas-liquid separator; withdrawing a liquid stream from the gas-liquid separator; and liquefying an ammonia gas stream in an ammonia liquefier by indirect contact with the liquid stream from the gas-liquid separator, thereby forming a liquid ammonia stream and a gaseous carbon dioxide stream.

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.
