This report summarizes the results of organic acid addition tests at a commercial FGD system. The tests were conducted at San Miguel Electric Cooperative's 410 MW lignite-fired Unit 1, outside Jourdanton, TX. During the program, several organic acid mixtures were tested over a range of operating conditions to determine if the use of organic acids would allow San Miguel to reduce RGD system operating costs. Based on the test results, a cost analysis indicated that the use of organic acid addition at San Miguel will result in a first-year cost savings of over $600,000. In terms of cumulative net present worth, the estimated savings over a 15-year period will be $7.2 million in 1984 dollars.
