PLANT FOR PRODUCING CARBON DIOXIDE FROM A COMBUSTION GAS, AND METHOD

Claims

The plant (1; 301; 401) comprises a heat exchanger (37; 337; 437) adapted to receive compressed combustion gas containing carbon dioxide and to condense at least some of the carbon dioxide contained therein. A carbon dioxide removal unit (39; 39; 439) of the plant is adapted to remove liquefied carbon dioxide from the combustion gas exiting the heat exchanger (37; 337; 437). A carbon dioxide outlet duct (61; 391; 479) extends through the heat exchanger (37; 337; 437). The plant further includes a distillation section (6; 306; 406). The distillation section includes a distillation column (201; 360, 501), a reheater (203; 363; 505) at the bottom of the distillation column (201; 360; 501) and a column head condenser (205; 361; 503) at the top of the distillation column (201; 360; 501).This document also describes a method for removing carbon dioxide from a combustion gas.
