METHOD AND PLANT FOR CO2 CAPTURING

摘要

A method and a plant for capturing CO<SUB>2</SUB> from an exhaust gas from combustion of carbonaceous material are described. At least a part of the combustion gas is introduced into a biol fuel boiler as an oxygen containing gas, to increase the concentration of CO<SUB>2</SUB> and decrease the oxygen concentration in the gas before introduction into an absorption column for separation of CO<SUB>2</SUB>.
