Abstract
A device for separating a gas mixture into product gas and offgas by way of gas permeation includes four membrane units and a compressor connected upstream of the first membrane unit. The membrane units have a gas inlet, a retentate outlet and a permeate outlet. Lines connect the membrane units to each other and to the compressor. Product gas is obtained via the permeate outlet of the second membrane unit and offgas via the retentate outlet of the first membrane unit. Additional product gas is obtained via the retentate outlet of an upstream membrane unit and additional offgas is obtained via the permeate outlet of a further upstream membrane unit. A method includes use of the device to separate a gas mixture into product gas and offgas.
