The report gives results of a detailed comparative technical and economic evaluation of limestone slurry, generic double alkali, and citrate flue gas desulfurization (FGD) processes, assuming proven technology and using representative power plant, process design, and economic premises. For each process, economic projections were made for a base case (500 MW, 3.5% sulfur coal, new unit) and case variations in power unit size, fuel type, sulfur in fuel, new and existing power units, waste slurry ponding and filter cake trucking, and SO2 removal (1.2 lb SO2 allowable emission per million Btu heat input vs 90%). Depending on unit size and status, fuel type and sulfur content, solids disposal method, and overall project scope, ranges in estimated capital costs in 1979 dollars are $71 to $127/kW for limestone slurry, $80 to $130/kW for generic double alkali, and $105 to $194/kW for citrate (recovery process). Results can be scaled or altered to reflect other site-specific conditions. Capital investment, annual revenue requirements (7000 hr/yr), and lifetime revenue requirements over a 30-year declining operating profile were estimated for the base case and each variation. Investment costs were projected to mid-1979; annual revenue requirements were calculated in projected mid-1980 dollars. Effects of variations in various cost parameters were studied.
