Abstract
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.
