Sulfur dioxide is scrubbed from boiler flue gases in a double-loop alkali scrubber, one a quencher loop and the other an absorption loop. The reagent flow of the two loops is isolated so that none of the reagent from the quencher loop is cycled to the absorber loop and a portion of the make-up water for the quencher loop is received from the absorber loop. By controlling recycled water from a dewatering system and selective utilization of high and low solids streams from the absorber system, the quencher slurry concentration may be controlled and the requirement for new make-up water reduced. The two loop process isolates the main absorber system including the demisters, which are prone to scaling and corrosion, from the evaporative quencher portion of the process. All the recycled water is returned to the evaporative quencher loop and none to the loop controlling the demisters and the primary absorber sections. However, under varying SO. sub.

An impingement or rebound separator for removing mist from a flow of gas consists of a first series of spaced eliminator blades each having at least one of its ends connected to an end plate with the transverse axis of each blade sloping at an angle of about 20. degree. to about 30. degree. to the direction of flow of gas and a second series of spaced eliminator blades each having at least one of its ends connected to an end plate and with the transverse axis of each blade sloping at an angle of about 20. degree. to about 30. degree. to the direction of flow of gas but pitched in the opposite direction to the pitch of the first series of blades. The first and second series of blades defining a separator unit having a plurality of zig-zag or chevron shaped gas flow channels with the longitudinal axes of the blades tilted at an angle of about 30. degree. to about 45. degree. to the direction of flow of the gas stream so that liquid removed from the gas stream will be channeled downstream along the edges of each blade to collection means which may comprise the lower end plates.
