| abstract |
The invention relates to a method for separating carbon dioxide from an exhaust gas of a fossil-fired power plant, in which a fossil fuel is burned in a combustion process (1), wherein a carbon dioxide-containing exhaust gas (2) is generated, in which exhaust gas containing carbon dioxide in an absorption process (3) (2) is brought into contact with an absorption medium, wherein carbon dioxide is taken up by the absorption medium, wherein a laden absorption medium (4) and a purified exhaust gas (5) is freed from carbon dioxide, and in which in a desorption process (6 ) is discharged from the loaded absorption medium (4) gaseous carbon dioxide (7), wherein regenerated absorption medium (8) is formed, wherein in the desorption process (6) the loaded absorption medium (4) is first partially regenerated in at least one Vorregenerierungsschritt (9), and in an end regeneration step (10) following the pre-regeneration step (9) d As laden absorption medium (4) is regenerated. |
