The second most common use of CCPs is flue gas desulfurization (FGD) gypsum in wallboard. This material is produced by emissions control systems (scrubbers) that remove sulfur and oxides from power plant flue gas streams. Residues vary, but the most common uses in construction applications are FGD gypsum (or quot;syntheticquot; gypsum).

FGD issues affect, directly or indirectly, coal, gypsum, lime, limestone, and soda ash industries. Increased commercial use of FGD products represents an economic opportunity for highsulfur coal producers and the sorbent industry. Synthetic gypsum competes directly with natural gypsum as raw material for wallboard and cement manufacture.

SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime

A process for reducing the sulfur and ash content of coal wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coaloil aggregates. The coaloil aggregates are separated from ash and mineral matter in the slurry by dissolved gas flotation. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation step.
