Abstract: A gas sparger (30) is operative for supplying an oxidation gas containing oxygen to a tank (18) of a wet scrubber which is operative for removing sulphur dioxide from a process gas by means of a slurry (S). The gas sparger (30) is provided with at least a first liquid supply nozzle (38), which is located inside an oxidation gas supply duct (32) and is operative for spraying a liquid containing water towards a first oxidation gas supply nozzle (44). The oxidation gas supply duct (32) has a characteristic cross-sectional measure, such as a diameter (D), at said first oxidation gas supply nozzle (44). The first liquid supply nozzle (38) is located a distance (L1) of maximum 5 times said characteristic cross-sectional measure (D) from said first oxidation gas supply nozzle (44).

Abstract: A device (1) for separating sulphur dioxide from a gas (4) by means of an absorption liquid has an inlet (2) for gas (4) containing sulphur dioxide, an outlet (18) for gas (16), from which sulphur dioxide has been separated, and as essentially horizontal apertured plate (8), which is arranged to allow passage from below of sulphur dioxide containing gas (4) and to carry, on its upper side (12), a flowing layer (14) of the absorption liquid. An outlet box (20) beside the apertured plate (8) is arranged to be passed by liquid, which is distributed in the gas (4) coming from the inlet (2). A first pumping means is arranged to feed a coolant flow to the outlet box (20) and a second pumping means is arranged to feed an absorption liquid flow, which is essentially independent of the coolant flow, to the apertured plate (8) to form the flowing layer (14). In a method of separating sulphur dioxide, the above-described device (1) can be used.

Abstract: A wet electrostatic precipitator (1) comprises an inlet (2) for receiving a gas (4) containing a pollutant, and an outlet (6) for discharging therefrom the gas (8) from which said pollutant has been at least partially removed. Nozzles (24) are operative for purposes of spraying liquid onto at least one first vertical collecting surface (30) of at least one collecting electrode (18). A liquid distributor (42) is provided for purposes of pouring liquid onto at least one second vertical collecting surface (44), said at least one second vertical collecting surface (44) being located on a further collecting electrode (36), with said further collecting electrode (36) being located downstream of said at least one collecting electrode (18). The nozzles (24) are located upstream of the liquid distributor (42), as viewed with reference to the direction of flow of the gas. In a method of cleaning the collecting electrodes (18, 36) an upstream electrode (18) is sprayed with liquid while liquid is poured onto a downstream collecting electrode (36).
