METC is constructing an on-site, fluid-bed, hot-gas desulfurization (HGD) process development unit (PDU) to support the US Department of Energy`s (DOE) Integrated Gasification Combined Cycle power systems program. Once operational, this PDU will be used to develop process scale-up and performance data for a number of configurations and to demonstrate fully coupled sulfidation-regeneration operations. Its size and gas throughput should also enable the PDU to address some of the actual engineering design and control issues associated with fluid-bed, HGD processes. Fluid beds and transport reactors, either alone or in combination, are conceptually attractive for HGD processes for a number of reasons, including: Continuous steady-state operation, which simplifies system control strategies; good temperature control, which reduces the potential for sorbent sintering during regeneration; and potentially wide range of regeneration gas SO{sub 2} concentrations, which adds to process flexibility for sulfur recovery options. The METC Office of Technology Base Development has been providing lab- and bench-scale experimental support to DOE`s fluid-bed, HGD development efforts since 1988. This continuous-flow PDU will enable further technology development and testing to proceed at a much larger engineering scale.
