SEPARATION OF GASES |
摘要 |
A method for the separation of at least one constituent gas from a gas mixture containing the at least one constituent gas and at least one other gas species is described, the method comprising the steps of: providing a stream of the gas mixture to a first membrane of a zeolite material under conditions of pressure and temperature such that the required gas is selectively adsorbed onto a first face of the zeolite material membrane and diffusion through the zeolite membrane towards a second face is promoted; retaining and containing the permeate gas emerging from said membrane second face and passing a retentate of said gas stream not passed through said zeolite membrane either back to the first face of the first zeolite membrane or to a first face of a second zeolite membrane; and, repeating said method steps until a content of the required gas in the gas mixture is reduced to a desired level.
