摘要：The method compris burning a fossil fuel in a combustion process (1) to
produce carbon dioxide-containing exhaust gas (2), contacting the carbon dioxide-containing exhaust gas with an absorption medium (4) in an absorption process (3) to absorb carbon dioxide by the absorption medium such that a loaded absorption medium and a purified exhaust gas is formed, which is free from exhaust gas, and delivering the gaous carbon dioxide from the loaded absorption medium into a desorption process to form regenerated absorption medium. The method compris burning a fossil fuel in a combustion process (1) to produce carbon dioxide-containing exhaust gas (2), contacting the carbon dioxide-containing exhaust gas with an absorption medium (4) in an absorption process (3) to absorb carbon dioxide by the absorption medium such that a loaded absorption medium and a purified exhaust gas is formed, which is free from exhaust gas, and delivering the gaous carbon dioxide from the loaded absorption medium into a desorption process to form regenerated absorption medium. A gas-vapor mixture is formed from the gaous carbon dioxide and vaporous absorption medium. The loaded absorption medium in the desorption process is initially regenerated in a pre-regeneration step in a partial manner, is regenerated in a final regeneration step following the pre-regeneration step, and is partially regenerated in veral pre-reg

eneration steps. The gaous carbon dioxide is thermally driven from the loaded absorption medium into the desorption process. The pre-regeneration step for partially regenerating the loaded absorption medium is carried out in a pre-cleaning temperature, and the final regeneration step for regenerating the loaded absorption medium is carried out in a final cleaning temperature. The pre-cleaning temperature is adjusted less than final cleaning temperature. The heat for the pre-cleaning temperature is provided by low-temperature steam in the pre-regeneration step and the heat for the final-cleaning temperature is provided by superheated steam in the final regeneration step, where the heat is guided with the loaded absorption medium into a heat exchanger in a heat exchanging process. The superheated steam is adjusted to a high temperature than the temperature of the low-temperature steam. A low-temperature steam is ud with a temperature of 60-120[deg] C. A high-value superheated steam is ud with a

temperature of 120[deg] C. The absorption medium is a liquid such as fluid, gas, aerosol or suspension. A vaporizable solvent is ud as fluid and is a solution made of water and amine derivatives. The heat in a preheating process (15) is removed from the regenerated absorption medium, and is delivered to the loaded absorption medium. The carbon dioxide parated from the exhaust gas is compresd in a compression process to develop a compresd or liquefied carbon dioxide, which is stored. An independent claim is included for a fossil fuel-powered power plant.
