Abstract
An SO.sub.2 flue gas scrubbing system wherein a calcium compound is dissolved in water and recirculated in contact with the flue gases. Calcium sulfite and sulfate formed in this process are also recirculated. A stream of the slurry passing to waste is separated based on the rate of settling of the constituents so that calcium sulfate and undissolved calcium compound is returned to the recirculating system with the calcium sulfite being sent to waste.
