Bench-scale demonstration of hot-gas desulfurization technology. Quarterly technical progress report, October 1--December 31, 1993

PDF Version Also Available for Download.

Description

Research Triangle Institute (RTI) with DOE/METC sponsorship has been developing zinc titanate sorbent technology since 1986. In addition, RTI has been developing the Direct Sulfur Recovery Process (DSRP) with DOE/METC sponsorship since 1988. Fluidized-bed zinc titanate desulfurization coupled to the DSRP is currently the most advanced and attractive technology for sulfur removal/recovery for IGCC systems, and it has recently been proposed in a Clean Coal Technology project. The goal of this project is to continue further development of the zinc titanate desulfurization and DSRP technologies by: scaling up the zinc titanate reactor system; developing an integrated skid-mounted zinc titanate desulfurization-DSRP ... continued below

Description

Research Triangle Institute (RTI) with DOE/METC sponsorship has been developing zinc titanate sorbent technology since 1986. In addition, RTI has been developing the Direct Sulfur Recovery Process (DSRP) with DOE/METC sponsorship since 1988. Fluidized-bed zinc titanate desulfurization coupled to the DSRP is currently the most advanced and attractive technology for sulfur removal/recovery for IGCC systems, and it has recently been proposed in a Clean Coal Technology project. The goal of this project is to continue further development of the zinc titanate desulfurization and DSRP technologies by: scaling up the zinc titanate reactor system; developing an integrated skid-mounted zinc titanate desulfurization-DSRP reactor system; testing the integrated system over an extended period with real coal-gas from an operating gasifier to quantify the degradative effect, if any, of the trace contaminants present in coal gas; developing an engineering database suitable for system scaleup; and designing, fabricating and commissioning a larger DSRP reactor system capable of operating on a six-fold greater volume of gas than the DSRP reactor used in the bench-scale field test. During this reporting period the Construction Permit Application was completed and approved by the Process Safety Committee, and a final revised Application has been submitted to DOE/METC. A draft Test Plan for the field test was formulated. Finally, progress was made in the reactor system fabrication with the submission of purchase orders for nearly all major equipment, and with the final design of the trailer (mobile laboratory).
