Pilot Plant Tests of Chloride Ion Effects on Wet FGD (Flue Gas Desulfurization) System Performance

摘要

The report gives test results from September 1981 through June 1983 of a chloride ion--Cl(-1)--effects test program on a wet flue gas desulfurization (FGD) pilot plant, at EPA's Industrial Environmental Research Laboratory, Research Triangle Park, NC. Tests were conducted on a three-stage turbulent contact absorber (TCA) with 7.5 cu m/min (0.1 MW) flue gas capacity at Cl(-1) concentrations of 160-180,000 ppm. The FGD processes investigated include conventional lime/limestone, magnesia enhanced limestone, organic dibasic acid (DBA) enhanced limestone, and limestone with two-tank forced oxidation. Data indicate that the effects of Cl(-1) on the performance of the limestone scrubber are a function of cations associated with Cl(-1) and scrubber operating conditions.
