Title: Status of spray-dryer flue-gas desulfurization. Final report

Abstract

Utility interest and commitment to spray drying for SO/sub 2/ and particulate control has increased dramatically in response to vendor claims (lower costs, dry wastes, lower energy requirements, and simplicity) and newly promulgated federal emission regulations that allow lower SO/sub 2/ removal requirements (70%) for low-sulfur coals. Unfortunately, limited data are available from which to evaluate vendor claims prior to commercial commitment or to improve the cost and reliability of this potentially important flue gas desulfurization (FGD) option. Accordingly, EPRI is conducting a pilot-scale project (RP1870) to provide a systematic evaluation of the technology unconstrained by specific vendor designs, operating philosophy, or commercial limitation. It will result in guidelines for system design and optimization in order to ensure reliable utility operation at minimum cost. This final report (TPS 80-741) contains a review of the design practices for the full-scale systems ordered and a discussion of the important spray-drying FGD process variables. Other EPRI work in this area includes a cost study with the Tennessee Valley Authority (RP1180-7) and a spray-dryer waste solids characterization (RP1870-2). The EPA has published a similar status document, which, in addition to spray drying, also covers dry injection and burning coal-alkali mixtures. However, the EPA documentmore » is not as detailed on either the design of full-scale systems or the technical issues.« less
