Abstract
A nitrogen oxide absorbing unit, a nitrogen oxide absorbing liquid extraction line, a nitrogen oxide absorbing liquid heating/regenerating unit, a released gas line, and a regenerated liquid discharge line are provided. The nitrogen oxide absorbing unit is configured to absorb and remove nitrogen oxides in exhaust gas with nitrogen oxide absorbing liquid by introducing the exhaust gas containing nitrogen oxides and carbon dioxide. Through the nitrogen oxide absorbing liquid extraction line, the circulating nitrogen oxide absorbing liquid is extracted from a nitrogen oxide absorbing liquid circulation line. The nitrogen oxide absorbing liquid heating/regenerating unit is configured to obtain released gas containing at least nitrogen monoxide and carbon dioxide and nitrogen oxide absorbing liquid regenerated liquid by subjecting the nitrogen oxide absorbing liquid to heating and regeneration treatment. Through the released gas line, exhaust gas from the nitrogen oxide absorbing unit is introduced to the released gas.
