Anion-exchange resin-based desulfurization process. Quarterly technical progress report, October 1, 1992--December 31, 1992
Under DOE Grant No. DE-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. During the reporting period, October 1, 1992--December 31, 1992, UTSI has completed the batch mode experiments to evaluate the performance enhancement effect caused by organic acids on the resin`s exhaustion efficiency. At present, batch mode experiments are being conducted to locate the position of the CO{sub 3}= and SO{sub 4}= ions in the affinity chart, and also reviewing/assessing the ASPEN Code`s capabilities for use in the development of the Best Process Schematic and related economics.
