Advanced sulfur control concepts in hot-gas desulfurization technology. Quarterly report, April--June 1994
The primary objective of this research project is the direct production of elemental sulfur during the regeneration of known high temperature desulfurization sorbents. The contract was awarded to LSU on April 12, 1994, and this quarterly report covers accomplishments during the first 2 1/2 months of the project. Effort during the initial 2 1/2 month period has been limited to Tasks 1 and 2, and involves a search of the literature to identify concepts for producing elemental sulfur during regeneration of known metal oxide sorbents and a thermodynamic evaluation of these concepts. While searching and evaluating the literature is a continuing process, concentrated effort on that phase is now complete and a detailed summary is included in this report. Three possible concepts for the direct production of elemental sulfur were identified in the LSU proposal, and the literature search has not uncovered any additional concepts. Thus, the three concepts being investigated involve: (1) regeneration with SO{sub 2}, (2) regeneration with mixtures Of 02 and H{sub 2}O, and (3) regeneration with H{sub 2}O. While concept (3) directly produces H{sub 2}S instead of elemental sulfur, the concept is included because the possibility exists for converting H{sub 2}S to elemental sulfur using the Claus process. Each of the concepts will ultimately be compared to the Direct Sulfur Recovery Process (DSRP) under development by RTI. DSRP involves initial sorbent regeneration to SO{sub 2}, and the inclusion of additional processing steps to reduce the SO{sub 2} to elemental sulfur.
