Abstract The report gives results of the initial two phases of pilot-plant work done by TVA for the EPA on an ammonia absorption/ammonium bisulfate regeneration process for removing SO2 from stack gas of coal-fired power plants. The work was carried out sequentially in two pilot plants at TVA's Colbert Power Plant in northwest Alabama: the first plant was used to study the absorption process only; the second, to study both the ammonium bisulate regeneration step and the absorption step. Both pilot plants were designed for about 4000 acfm of flue gas at 300F. The principal variables studied were: inlet flue gas temperature, recirculated absorber liquor pH, opacity of the plume leaving the absorber stack, oxidation of sulfite to sulfate in the absorber liquor, and the fly ash level in the flue gas entering the absorber.
