摘要

The flue gas treatment system (10) for a boiler (11) comprises a gas purifying unit (40) and a carbon dioxide separation unit (26) downstream of the gas purifying unit (40). The gas purifying unit (40) comprises a first compression step (19), a selective catalytic reduction unit (SCR) downstream of the first compression step (19), a second compressor step (20) downstream of the selective catalytic reduction unit (SCR).
