EXHAUST GAS TREATMENT SYSTEM WITH CO2 REMOVAL EQUIPMENT
An object of the present invention is to provide a CO 2 removal equipment for removing CO 2 in a combustion exhaust gas and a method therefore, which can reduce environmental burdens during operation of the CO 2 removal equipment, and which can minimize the installation cost of a prescrubber and utility costs. Provided is an exhaust gas treatment system with a CO 2 removal equipment for absorbing and removing carbon dioxide (CO 2 ) in a combustion exhaust gas using an absorbing solution of an amine compound, the system comprising a prescrubber for bringing the exhaust gas into contact with seawater, the prescrubber being disposed on the upstream side of the CO 2 removal equipment.
1 . An exhaust gas treatment system with a CO 2 removal equipment for absorbing and removing carbon dioxide (CO 2 ) in a combustion exhaust gas using an absorbing solution of an amine compound, the system comprising a prescrubber for bringing the exhaust gas into contact with seawater, in which the prescrubber is disposed on the upstream side of the CO 2 removal equipment.
2 . The exhaust gas treatment system according to claim 1 , wherein
the exhaust gas treatment system comprises a wet-type exhaust gas desulfurization device, and
the prescrubber is disposed downstream the wet-type exhaust gas desulfurization device and has a function of cooling an outlet exhaust gas of the wet-type exhaust gas desulfurization device.
3 . The exhaust gas treatment system according to claim 1 , wherein the amine compound is alkanolamine.
