Abstract: A method and corresponding apparatus for separation of carbon dioxide from an exhaust gas of a fossil-fired power are provided. In an absorption process, the exhaust gas containing carbon dioxide is brought into contact with an absorption medium so that the absorption medium is laden with carbon dioxide. In a desorption process, vapor from a water/steam circuit of the fossil-fired power plant is heated, wherein a laden absorption medium is regenerated. In a subsequent expansion process, the regenerated absorption medium is expanded so that a vapor and an expanded absorption medium are formed, wherein the vapor is recirculated into the desorption process. The laden absorption medium is divided into a first part stream and a second part stream. Only the second part stream is brought into heat-exchanging contact with the expanded absorption medium. The first and second part streams are supplied to the desorption process at different process stages.
