Investigation of high SO/sub 2/ removal design and economics. Final report. Volume 2. Economics
The Clean Air Act Amendments of 1977 require the Environmental Protection Agency to set new standards for control of sulfur dioxide emissions. SRI International estimated capital costs and incremental revenue requirements for flue gas desulfurization (FGD) to meet increasingly stringent SO/sub 2/ removal requirements. These costs were estimated by SRI for 14 conceptual designs based on process conditions and material balances determined by Radian Corporation. Analyses of these designs show the effects of various levels of SO/sub 2/ removal on the costs of burning eastern high-sulfur, high chlorine coal and western low-sulfur, low-chlorine (compliance) coal, using limestone, lime, and regenerative magnesia scrubbing. Total capital requirement for FGB ranges from $123 to $213/kW (January 1979 dollars), if 25% spare capacity is provided for reliability. The sulfur compliance coal chosen in this study does not require FGD under the old standard (520 ng/J or 1.2 lb SO/sub 2/ emission/million Btu), but the incremental 30-year levelized busbar cost is 8 to 9 mill/kWh if a high percentage of SO/sub 2/ removal is required. For eastern coal, revenue requirements increase less than 3 mill/kWh as removal requirements are tightened.
