Abstract
The paper gives results of an evaluation of solids dewatering for a pilot-scale thiosorbic lime SO2 scrubber. Pilot plant data showed that the dissolved magnesium in thiosorbic lime caused deterioration of solids dewatering properties. The slurry settling rate increased when the slurry shear stresses caused by the hold tank stirrer and recirculation pump were reduced. The application of flocculant also increased the slurry solids settling rate. Compared with rotary drum vacuum filtering, better liquid/solids separation occurred with a centrifuge. Other related performance results are also discussed.
