A method for removing and preventing discharge into the atmosphere of carbon dioxide from combustion gases and natural gas from installations for production of oil and/or gas, wherein the combustion gas is passed to an absorber containing a solvent, where carbon dioxide is absorbed in the solvent, and the thereby purified combustion gas, largely free of carbon dioxide, is released into the atmosphere, where the CO.sub.2 rich solvent is passed to a desorber where CO.sub.2 is removed from the solvent, and the thereby largely CO.sub.2 -free solvent is recycled to the absorber, and the separated CO.sub.2 gas is passed to a compression stage for compression and utilization and/or disposal in a suitable manner, where membrane gas/liquid contactors are employed in both the absorber and the desorber, and that an external stripping steam is supplied to the desorber.

[ What is claimed is:] [1.]1. A method for removing and preventing discharge into the atmosphere of carbon dioxide from flue gases and natural gas from installations for production of oil and/or gas comprising:removing carbon dioxide from said flue gases and said natural gas by passing said flue gas

[ What is claimed is:] [1.]1. A method for removing and preventing discharge into the atmosphere of carbon dioxide from flue gases and natural gas from installations for production of oil and/or gas comprising:removing carbon dioxide from said flue gases and said natural gas by passing said flue gases and said natural gas to an absorber that utilizes membrane gas/liquid contactors to absorb said carbon dioxide in a solvent, thereby substantially purifying said flue gases and said natural gas;releasing said flue gases to the atmosphere, wherein said flue gases and said natural gas are substantially free of carbon dioxide;separating said carbon dioxide from said solvent by passing said carbon dioxide and said solvent to a desorber, wherein said desorber uses membrane gas/liquid contactors and is supplied with an external stripping steam;recycling said solvent, wherein said solvent is largely free of carbon dioxide, to said absorber; andcompressing said carbon dioxide.
