Description:
The paper discusses a 100 cu m/h pilot facility (consisting of a spray dryer, a sorbent injection system, a duct section, and a pulse-jet baghouse or cyclone separator) used for testing the reaction at low temperature between various calcium- and sodium-based sorbents and SO2 in the concentration range of 1000-2500 ppm. The sorbents tested were based on earlier-reported sand-bed reactor (0.3 cu m/h) tests. The performance of these sorbents is compared in terms of SO2 removal and stoichiometry with that obtained using conventional slaked lime in spray drying or dry injection under similar conditions.
