Anion-exchange resin-based desulfurization process. Quarterly technical progress report, January 1, 1993--March 31, 1993
Under DOE Grant No. FG22-90PC90309, the University of Tennessee Space Institute (UTSI) is contracted to further develop its anion-exchange, resin-based desulfurization concept to desulfurize alkali metal sulfates. From environmental as well as economic viewpoints, it is necessary to remove soluble sulfates from the wastes created by flue gas desulfurization systems. In order to do this economically, a low-cost desulfurization process for spent sorbents is necessary. UTSI`s anion-exchange resin-based desulfurization concept is believed to satisfy these requirements. UTSI has completed the batch mode experiments to locate the position of the CO{sub 3}{sup 2} and SO{sub 4}{sup 2} ions in the affinity chart. Also, the reviews of the ASPEN Code`s capabilities and EPRI-TAG document`s methodology are in progress for developing the Best Process Schematic and related economics. The fixed-bed experiments are also in progress to evaluate the cycle efficiency of the candidate resins. So far we have completed ten consecutive cycles of exhaustion/carbonation and regeneration for IRA-35 resin. Because of the past problems (now resolved) with the fixed-bed system, the addition of batch mode screening experiments, Christmas holidays and spring break, and the moving of UTSI`s Chemistry Laboratory to a new location, the program is about 6--8 weeks behind schedule, but well within the budget.
