This volume presents the estimated costs for the NOXSO, High Sulfur Lime Spray Dryer, Saarberg-Holter/Limestone, SOXAL, Organic Acid Enhanced Limestone and Limestone with Wallboard Gypsum By-Product FGD systems based on December 1982 dollars and 1985 technology. These systems were evaluated for operability, technical merit, and commercial availability. Each FGD system was evaluated for a high sulfur coal application at a new, hypothetical 1000 MW (two 500 MW units) power plant located in Kenosha, WI. This arbitrary reference plant was selected to ensure consistent comparisons, and to increase the relative accuracy of the costs presented. The evaluation methods employed in this study were identical to those used in previous EPRI volumes of the report, CS-3342, ''Economic Evaluation of FGD Systems.'' A flow sheet, material balance, equipment list, system description, and utility consumption list form the basis of each FGD process evaluation. Cost information was obtained from process vendors, the Stearns Catalytic data base, and published reports. Capital costs were estimated by factoring costs of process equipment (i.e., an EPRI Class II estimate). Operating costs were estimated from reagent and utility consumption. The levelized capital and operating costs were developed using EPRI's standard economic premises. Costs have an absolute accuracy of +-30%. However, since methodology, scope, and unit costs are consistent, the relative accuracy between process estimates probably is +-15%. 88 figs., 64 tabs.
