The present invention relates to a novel membrane module for separating a fluid feed stream into a permeate stream and a retentate stream. The membrane module according to the invention is characterized in that all components are housed in a 20', 40&#x2032;, 45&#x2032; HC, 45&#x2032; PW or 53&#x2032; HC container, whereby the membrane module can be transported and handled in a very simple and cost-effective manner despite its comparatively large volume and its high weight. The membrane module is furthermore characterized by its large membrane surface area compared with usually used membrane modules, whereby the number of individual membrane modules required in practical use can be reduced many times over. The present invention furthermore relates to a process for separating a fluid feed stream into a permeate stream and a retentate stream using the membrane module according to the invention.

Membrane module

Carbon dioxide is separated from a flue gas produced in a combustion plant. Flue gas is supplied to a membrane unit having at least one membrane module provided with a membrane that is selective for CO. A portion of the COis separated from the flue gas in the module, producing a CO-enriched permeate. CO-depleted flue gas remaining on the retentate side of the module is supplied to at least one additional COseparating unit and a portion of the COin the retentate is separated by an absorbent. The result is a reduction in energy consumption.
