BENCH-SCALE DEMONSTRATION OF HOT-GAS DESULFURIZATION TECHNOLOGY

PDF Version Also Available for Download.

Description

Designs for advanced integrated gasification combined cycle (IGCC) power systems call for desulfurization of carbonaceous fuel-derived synthesis gas (syngas) using regenerable sorbents at high-temperature, high pressure (HTHP) conditions. Regeneration of the sulfided sorbent using an oxygen-containing gas stream or air results in a sulfur dioxide (SO{sub 2})-containing offgas at HTHP conditions. The patented Direct Sulfur Recovery Process (DSRP) developed by RTI with support from the National Energy Technology Laboratory (NETL) and its precursor organizations [Federal Energy Technology Center (FETC) and Morgantown Energy Technology Center (METC)] efficiently converts the SO{sub 2} in this offgas to elemental sulfur. Under development since 1988, ... continued below

Description

Designs for advanced integrated gasification combined cycle (IGCC) power systems call for desulfurization of carbonaceous fuel-derived synthesis gas (syngas) using regenerable sorbents at high-temperature, high pressure (HTHP) conditions. Regeneration of the sulfided sorbent using an oxygen-containing gas stream or air results in a sulfur dioxide (SO{sub 2})-containing offgas at HTHP conditions. The patented Direct Sulfur Recovery Process (DSRP) developed by RTI with support from the National Energy Technology Laboratory (NETL) and its precursor organizations [Federal Energy Technology Center (FETC) and Morgantown Energy Technology Center (METC)] efficiently converts the SO{sub 2} in this offgas to elemental sulfur. Under development since 1988, the original work was conducted in a laboratory with simulated laboratory gas mixtures. The Direct Sulfur Recovery Process is a catalytic reduction process for efficiently converting to elemental sulfur up to 98% or more of the sulfur dioxide (SO{sub 2}) contained in the regeneration offgas streams produced in advanced integrated gasification combined cycle (IGCC) power systems. The DSRP reacts the regeneration offgas with a small slipstream of syngas to effect the desired reduction. In this project, the DSRP was demonstrated with actual coal-derived syngas (as opposed to the simulated laboratory mixtures used in previous projects for the original development work) in 75-mm (3-in) and 125-mm (5-in) fixed- and fluid-bed reactors. This report focuses primarily on the slipstream testing of a skid-mounted DSRP field-test unit that utilized the 125 mm (5-in) fluid-bed reactor. This slipstream testing was conducted at the US Department of Energy's (DOE's) Power System Development Facility (PSDF) in Wilsonville, Alabama in conjunction with their coal gasification tests. The earlier work with 75 mm (3-in) reactors has been previously reported in detail. Thus, only the highlights of this earlier work will be reported in the main body of this report.
