Anion-exchange resin-based desulfurization process. Annual technical progress report, October 1, 1992--September 30, 1993
Under the DOE Grant No. DE-FG22-90PC90309, the University of Tennessee Space Institute (UTSI) has been directed to further develop an anion-exchange, resin-based desulfurization concept that has been developed and tested on a limited scope for feasibility. From environmental as well as the economic viewpoints, it is necessary that the soluble sulfates of alkali metal sorbents be desulfurized (regenerated) and recycled to make regenerative flue gas desulfurization and MHD spent seed regeneration 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 uses the available technology and is believed to satisfy this requirement. In this DOE-sponsored project, UTSI, will perform the following investigations: Screening of commercially available resins; process variables study and improving resin performance; optimization of resin-regeneration step; evaluation of performance enhancers; development of Best-Process Schematic and related economics, and planning for proof-of-concept (POC) scale testing. The above activities have been grouped into five major tasks and the entire project is expected to take thirty-six months to complete.
