Abstract
Flue gas that includes sulfur dioxide and alkali-containing flyash is cleansed in a liquid scrubber, followed by classification of discharge from the liquid scrubber into oversize and undersize fractions. The undersize fraction is clarified and recycled for use as a source of liquid scrubbing agent. The oversize scrubber discharge is reduced in particle size to expose more alkali-reactive surface and recycled into the scrubber for further reaction with SO.sub.2.
