    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.

    摘要： Exhaust gas from combustion equipment such as a boiler is brought into contact with an absorbing liquid to absorb sulfur oxide from the exhaust gas into the absorbing liquid. Limestone particles having larger diameters are selectively retained in a zone wherein the absorbing liquid that has absorbed the sulfur oxide from the exhaust gas is neutralized. The absorbing liquid containing water and the gypsum thereby formed, as main constituents, are selectively drained from the neutralizing zone and recycled for renewed contact with the exhaust gas. Because of the possibility of a large decrease of desulfurizing performance due to a variation in the load on the boiler, etc., at least one of the following is monitored: pressure drop across the neutralizing zone, torque of a stirring device, solids concentration in the absorbing liquid, specific gravity of the absorbing liquid and viscosity of the absorbing liquid. Responsive to the monitored parameters outlet SO.sub.2 concentration is controlled within a predetermined range by regulation of at least one of the following: flow rate of the absorbing liquid circulated into contact with the exhaust gas, amount of the solid desulfurizing agent added to the absorbing liquid, particle diameter of the solid desulfurizing agent and speed of agitation of the solid desulfurizing agent in the neutralizing zone.
