摘要： Hot process gases are passed through a contact reactor (10), in which a particulate absorbent material, which is reactive with gaseous pollutants in the gases, is introduced into the gases to convert the gaseous pollutants into separable dust. The process gases are then passed through a dust separator (5). The major part of the dust separated in the dust separator (5) is passed to a mixer (11), in which it is mixed and moistened, whereupon it is recirculated as absorbent material by being introduced, together with fresh absorbent, into the process gases. Burnt lime is added as fresh absorbent. The dust is kept so long in the mixer and recirculated so many times that the total residence time of the burnt lime in the mixer in moistened state is sufficiently long for the burnt lime to react substantially completely with water supplied to the mixer and form slaked lime.

摘要： A process for oxidizing a sulphite-ion-containing and/or hydrogen-sulphite-ion-containing aqueous solution in the presence of lime, preferably in wet flue-gas desulphurisation. In the process, lime, preferably calcium carbonate, is added to at least a part of the aqueous solution, and this part of the solution is then contacted with an oxygen-containing gas, such as air, before any precipitation of calcium sulphite has occurred. The oxygen-containing gas should be blown into the solution within 1 min of the addition of lime, preferably within 30 s, and most preferred within 5 s. It is further preferred that the solution be vigorously agitated, e.g. by means of a stirrer or a pump, when the process is implemented. The added lime should have a minimal particle size, and the average particle size preferably should not exceed about 30 mu m. It is preferred that the process be implemented at a temperature of about 40-60 DEG C.

摘要： In a method of separating gaseous pollutants from hot process gases, the process gases are passed through a contact reactor (22), in which an absorbent material in a moistened state is introduced to convert the gaseous pollutants into separable dust. The dust is separated in a dust separator (10). The separated dust is cooled in a first step by being brought into direct contact with a cooling fluid. In a second step, the cooled dust is mixed with a gas containing water vapour, said gas having a saturation temperature that is higher than the temperature of the cooled dust. The dust moistened by condensation of the water vapour is introduced into the contact reactor (22) to be mixed with the process gases. A mixer (24) for moistening of absorbent material has a first end (26) and a second end (28) and is divided into two zones. A first zone is a cooling zone (68) located at the first end (26). A second zone is a moistening zone (80) located at the second end (28).
