The program included: literature survey; preliminary economic evaluation for comparative purposes; selection of candidate processes; and process simplification and improvement of each candidate existing process; demonstration of process feasibility of any candidate new process; plant-scale evaluation and cost estimates for the candidate processes to both new and existing power plant facilities and to a new smelter facility. Of the four candidate processes the Zinc Oxide process was considered to merit further study, both in the form of a fluidized bed and in the form of the original Na+ scrubbing process to the small-scale pilot stage. The three remaining candidate processes (Cominco Exorption, Ammonia-Hydrazine Exorption, and Mitsubishi Lime) are not considered to be as economically attractive as the original Johnstone process. A major problem confronting any aqueous process in which sulfur dioxide is recovered as such is that of oxidation in the scrubber. Nearly 700 references are listed, with an author index. (Author)
