Abstract
A carbon dioxide recovery system includes: a plurality of absorption towers each disposed for each of a plurality of combustion equipments for absorbing carbon dioxide in an exhaust gas discharged from each of the plurality of combustion equipments into an absorption liquid by bringing the exhaust gas into contact with the absorption liquid; and at least one regeneration tower communicating with each of the plurality of absorption towers, for recovering carbon dioxide from a CO2 rich absorption liquid which is the absorption liquid flowing out of each of the plurality of absorption towers. The regeneration tower is smaller in number than the absorption towers.
