Results of the first two years of commercial operation of an organic-acid-enhanced FGD (flue gas desulfurization) system. Final report April 1982-April 1984
The report documents the first 2 years (1982 and 1983) of commercial operation of the dibasic acid (DBA) system at Springfield's Southwest Power Plant (SWPP), during which SWPP averaged an SO2 emission rate of less than 1.0 lb SO2/million Btu. (NOTE: EPA has sponsored research to develop organic-acid-enhanced flue gas desulfurization (FGD) technology for existing and new coal burning facilities. A 1981 EPA-sponsored demonstration program at SWPP, near Springfield, MO, showed that adipic acid and DBA greatly enhanced FGD performance. SWPP has continued to use DBA to comply with the 1971 SO2 emissions standard under which they are regulated. Thus, SWPP became the first commercial-scale system to use an organic additive to enhance SO2 removal). At SWPP in 1980 (before DBA addition), SWPP averaged about 5 lb SO2/million Btu. FGD system reliability was also greatly improved, averaging 97.9% in 1982 and 98.7% in 1983, compared to 45% in 1980. The SO2/O2 continuous emissions monitoring system also showed excellent reliability, exceeding 97%. Overall, DBA has increased the flexibility of the SWPP system and, most importantly, allowed SWPP to operate in compliance.
