A METHOD OF TREATING A CARBON DIOXIDE RICH FLUE GAS AND A FLUE GAS TREATMENT SYSTEM

摘要

The invention refers to an arrangement of a flue gas treatment system (1) and a combustion device (2). The flue gas treatment system (1) comprises a recirculation line (10) to supply at least a part of the flue gas from the combustion device (2) back to the combustion device (2), a selective catalytic reduction unit (SCR), a gas processing unit (GPU) to separate CO 2 from the flue gas. The recirculation line (10) departs upstream of the selective catalytic reduction unit (SCR), and the selective catalytic reduction unit (SCR) is upstream of the gas processing unit (GPU).
