摘要

The report gives results of a demonstration of key process steps in the proprietary Kel-S process for recovering calcium carbonate and sulfur from lime/limestone flue gas desulfurization (FGD) scrubber waste. The steps are: reduction of the waste to calcium sulfide (using coal as the reducing agent), carbonation of the calcium sulfide to generate hydrogen sulfide and calcium carbonate, and recovery of precipitated calcium carbonate from inerts (coal ash).
