The CO2 removal apparatus includes a desorption column 13 that heats and regenerates an amine compound aqueous solution discharged from a decarbonator 1 making counterflow contact of a combustion exhaust gas and an amine compound aqueous solution; and reflux means that refluxes an amine compound aqueous solution regenerated in the desorption column 13 to the decarbonator 1 via a cooler 19. A contact section that makes counterflow contact of reflux water of the desorption column 13 and a CO2-removed combustion exhaust gas is formed in two stages, and the cooler 19 on the downstream side of the desorption column is also formed in two stages. Reflux water from the first stage cooler is supplied to the first stage contact section, and reflux water from the second stage cooler is supplied to the second stage contact section. As a result, the reflux water from the cooler 19 on the downstream side of the desorption column 13 can be efficiently used for amine removal of the decarbonator 1, and a concentration of an amine released from the decarbonator can be reduced.

摘要： A wet-type flue gas desulfurization method and plant making use of a solid desulfurizing agent in which exhaust gas exhausted from a combustion apparatus such as a boiler is brought into contact with absorbing liquid to absorb sulfur oxide from the exhaust gas into the absorbing liquid followed by neutralization of the absorbing liquid containing the sulfur oxide thus absorbed. The solid desulfurizing agent is selectively retained in an absorbing liquid neutralizing zone and the absorbing liquid, containing water as a main constituent and solid products formed from the absorbed sulfur oxide, is selectively removed from the neutralizing zone. In the neutralizing zone the upward flow of the absorbing liquid, optionally augmented by an upward flow of air or water, forms a fluidized bed of limestone particles, thereby preventing coating of the limestone by gypsum and thereby retaining reactivity of limestone. According to the present invention, coexistence of Al and F in the absorbing liquid seldom deteriorates the desulfurizing performance. Further, it is possible to reduce power and cost required to grind limestone and to achieve a higher desulfurizing performance.
