Regeneration of FGD dry sorbent materials. Phase II. Final report
An aqueous process was developed to regenerate spent alkaline sorbent materials. These dry materials, injected directly into the flue gas duct, are used to control sulfur dioxide (SO/sub 2/) in the flue gases from coal burning power plants. The dry alkali injection technique is a developing technology being considered as an alternative to wet scrubbing. Wet scrubbing is currently the most widespread method employed by large coal-fired power plants for desulfurizing flue gas to meet New Source Performance Standards (NSPS) promulgated by the Environmental Protection Agency (EPA). In Phase I of this program, the conceptual process was developed and verified in laboratory-scale experiments, and the flow diagram and material balance for a 10-pound-per-hour spent sorbent regeneration unit were developed. Two alternate processes were also studied. The Phase I work has been reported in Regeneration of FGD Dry Sorbent Materials. Phase I: Final Report, by Versar Inc., DOE/FC/10179-2 (DE 82015597), May 1982. In Phase II, a 10-pound-per-hour regeneration model was designed, constructed, then transferred and reassembled at the Grand Forks Energy Technology Center (GFETC), where the proposed process was experimentally demonstrated. 11 references, 19 figures, 31 tables.
