EPA Paper No. 650/2-74-126-B, :1049-1067
A pilot plant was constructed by the Bureau of Mines and operated jointly by the Bureau and the Bunker Hill Company at a lead smelter in Kellogg, Idaho, to study the citrate process for removing so2 from industrial waste gases, citric acid, and sodium thiosulfate, and followed by reacting the absorbed so2 with h2s to precipitate elemental sulfur and to regenerate the citrate solution for recycling. General features and operating results for a pilot plant are summarized. Process economics for coal-fired boiler flue gas desulfurization are projected on the basis of the pilot plant operations.
