Abstract
The paper discusses two series of bench-scale dry flue gas desulfurization (FGD) laboratory tests, the primary objective of which was to evaluate the ability of a bench-scale dry FGD system to screen potential reagents and operating conditions in support of testing at larger pilot plant or full-scale systems. The first series consisted of once-through and recycle tests with hydrated lime reagent using a laboratory spray dryer/fabric filter system rated at 0.024 cu m/s. These tests duplicated conditions in similar tests with the 2.5 MW spray dryer/fabric filter pilot plant at the EPRI Arapahoe Test Facility. In the second series, the bench-scale spray dryer/fabric filter system was modified to permit the dry injection of reagents upstream of the baghouse. The series was designed to simulate dry sorbent injection. Several sodium bicarbonate reagents and a calcium-based reagent were tested. Test results and the feasibility of using the bench-scale system for screening sorbents and operating conditions are discussed.
