This report characterizes the chemical and mechanical environments to which the structural components used in flue-gas desulfurization (FGD) are exposed. It summarizes the necessary background information pertinent to various FGD processes currently in use, with particular emphasis on lime/limestone scrubbing technology, so that the materials problems and processing variables encountered in FGD systems can be better defined and appreciated. The report also describes the materials currently used and their performance to date in existing wet scrubbers. There is little doubt that with more extensive use of coal and flue-gas scrubbers by utilities and other segments of private industry, a better understanding of the material failure mechanisms, performance limitations, and potential problem areas is required for the design of more reliable and cost-effective FGD systems. To meet the above objectives, a materials evaluation program is proposed. The important experimental variables and the number of tests required to evaluate a given material are discussed. 55 references, 9 figures, 6 tables.
