Abstract
Sulfur dioxide is scrubbed from boiler flue gases in a double-loop alkali scrubber, one a quencher loop and the other an absorption loop. Preferably, 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. A substantial portion of the make-up water for the quencher loop is received from the absorber loop and solids are concentrated in a dewatering system which includes a hydroclone.
