ABSTRACT:
A method and an apparatus for removing carbon dioxide (CO2) from sulphur dioxide containing (SO2) flue gases, wherein the flue gases are washed with washing solution in a scrubber, which comprises at least two washing stages. In the first washing stage the flue gases are washed for removing the sulphur dioxide in the flue gases and after that in the second washing stage for removing carbon dioxide (CO2). Sodium carbonate solution (Na2CO3) is used as washing solution in both the first and the second washing stages.
