A 100 m/sup 3//h pilot facility incorporating a spray dryer, a sorbent injection system, a duct section, and a pulse jet baghouse or cyclone separator was used for testing the reaction at low temperature between various calcium- and sodium-based sorbents and SO/sub 2/ in the concentration range of 1000-2500 ppm. The specific sorbents selected for testing were based on earlier reported sand-bed reactor (0.3 m/sup 3//h) tests. The performance of these sorbents is compared in terms of SO/sub 2/ removal and stoichiometry with that obtained using conventional slaked lime in spray drying or dry injection at similar conditions.
