The U.S. Department of Energy`s Pittsburgh Energy Technology Center is evaluating the high-efficiency SO{sub 2} removal capabilities of existing electric utility flue gas desulfurization (FGD) systems. Full-scale tests have been conducted at six existing wet scrubbers, using chemical additives and other changes to increase the SO{sub 2} removal efficiency to a target value of 95 to 98%. The Electric Power Research Institute (EPRI) is also involved in the project, primarily by making available results from high-efficiency SO{sub 2} removal testing at their Environmental Control Technology Center and by using their FGDPRISM model as an analytical tool to support the fall-scale tests. This paper presents results from testing at the sixth site in this program, New York State Electric and Gas Corporation`s (NYSEG) Kintigh Station. The FGD system employs an open spray tower absorber, limestone reagent, and operates in an inhibited-oxidation mode. Sodium formate additive was evaluated as a performance upgrade option. Three types of tests were conducted from July through September of 1994. The first series of baseline (no additive) tests provided information about the {open_quotes}as-found{close_quotes} performance for the system. The second test series involved sodium formate addition, at levels ranging from 500 ppm to 3800 ppm in the absorber reaction tank. Finally, a one-week sodium formate additive consumption test was conducted. Results were used to calibrate EPRI`s FGDPRISM computer program and to evaluate the economics of using sodium formate additive to upgrade the SO{sub 2} removal performance of the Kintigh FGD system. The evaluation showed that more than 10,000 additional tons/year of SO{sub 2} could be removed at Kintigh at an average cost of only $76/ton removed.
