The paper gives results of pilot plant (0.1 MW) tests and utility boiler full-scale demonstration (194 MW) of byproduct organic dibasic acids (DBAs) as buffer additives to limestone scrubbers: performance improvements were achieved equivalent to those from adding pure adipic acid. Both SO2 removal efficiency and limestone utilization increased, and no significant operating problems were observed with three of the four DBAs tested. Chemical and biological evaluations of scrubber samples taken during the DBA testing indicated no detectable toxicity or mutagenicity, and no significant environmental impact is expected as a result of DBA addition. Economic estimates indicate that substitution of DBAs for pure adipic acid as a buffer additive will result in additive cost savings of 30 percent or greater.
