Demonstrations indicate that adipic acid and other organic buffering agents can improve the performance of limestone scrubbers for utilities using high-sulfur coal. Organic buffers used during the nine-month demonstration boosted the efficiency of sulfur dioxide (SO/sub 2/) removal from 70% to 95%. Despite legal incentives, the results are consistent with other industrial-scale and pilot-plant tests. Dibasic acids (DBA) had similar results. The low cost of buffer enhancing makes it a low-risk investment for utilities that need to bring their scrubbers into compliance with environmental standards. Scrubbers using adipic acid reduce capital costs 10% below conventional designs and annual operating costs 11%. 1 figure, 6 tables. (DCK)
