    摘要: The invention relates to a process and an apparatus for the treatment of a carbon dioxide-containing gas stream from a large-scale combustion plant, in particular of a power station. The gas stream is separated in a carbon dioxide purification stage R into a gas substream having an increased carbon dioxide content and a gas substream having a reduced carbon dioxide content. The gas substream having an increased carbon dioxide content is fed to a further use and/or storage S. In particular, compression of the carbon dioxide under the ground can reduce the emission of gases which affect the climate. To increase the proportion of compressible CO2, it is proposed that the gas substream having a reduced carbon dioxide content is fed to a pressure swing adsorption stage PSA in which a fraction which is rich in carbon dioxide and a fraction which is low in carbon dioxide are produced. The fraction which is rich in carbon dioxide is recirculated to the carbon dioxide purification stage R or is passed directly to further use and/or storage S.
