The University of Tennessee Space Institute (UTSI) has been directed to further develop an anion-exchange, resin-based desulfurization concept. It is necessary that the soluble sulfates of alkali metal sorbents be desulfurized (regenerated) and recycled to make regenerative flue gas desulfurization options more attractive. In order to achieve this, a low-temperature, low-cost desulfurization process to reactivate spent alkali metal sorbents is necessary. UTSI's anion-exchange, resin-based concept is believed to satisfy this requirement. Investigators will perform the following investigations: screening of commercially available resins; process variables study and improving resin performance; optimization of resin-regeneration; evaluation of performance enhancers; development of Best-Process Schematic and related economics; and planing for proof-of-concept (POC) scale testing. 2 refs., 3 figs., 3 tabs.
