Abstract:
1. A method for separation of carbon dioxide from a flue gas of a fossil-fueled power station, comprising: burning a fossil fuel in a combustion process coupled to a generator to provide a source of electric power, the combustion process producing a hot off-gas comprising carbon dioxide; bringing the hot off-gas comprising carbon dioxide into contact with an absorption medium in an absorption process where carbon dioxide is absorbed by the absorption medium forming a loaded absorption medium; thermally forcing out gaseous carbon dioxide of the loaded absorption medium in a desorption process and extracting a portion of the absorption medium from the loaded absorption medium; injecting a supply of steam into the loaded absorption medium, with the condensation heat released by condensation of the steam being transferred to the loaded absorption medium, wherein the steam supply injected into the loaded absorption medium is extracted from a steam generator process which is not coupled to the same combustion process or the generator of the power station which provides the source of electric power, and wherein the steam is injected into the desorption process at a plurality of points.
