Laseke, B. AND Jr. SURVEY OF FLUE GAS DESULFURIZATION SYSTEMS: WILL COUNTY STATION, COMMONWEALTH EDISON CO. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-78/048B.

Description:

The report gives results of a second survey of the flue gas desulfurization (FGD) system on Unit 1 of Commonwealth Edison Co.'s Will County Station. The FGD system, started up in February 1972, uses a limestone slurry in two parallel scrubbing trains. Each train includes a venturi scrubber, sump, and two-stage sieve tray absorber for the control of fly ash and SO2. The flue gas cleaning wastes are stabilized with lime and collected fly ash and hauled away to an off-site disposal area. The FGD system operated as an SO2-removal unit from February 1972 to July 1977, treating flue gas from the combustion of low sulfur western coal, high sulfur Illinois coal, and blends of both. Experimental SO2-removal operations were concluded in July 1977. The scrubbing system remains in service removing fly ash from low sulfur western coal flue gas. Some SO2 is removed from the flue gas during particulate-removal operations because of the alkalinity of the collected fly ash and the limestone additive used for pH control of the scrubbing solution.
