Book Synopsis Hot Gas Desulfurization with Sorbents Containing Mixed Metal Oxides by :
Download or read book Hot Gas Desulfurization with Sorbents Containing Mixed Metal Oxides written by and published by . This book was released on 1992 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced power generation systems such as the integrated gasification combined cycle power generators and the molten carbonate fuel cells have stringent fuel gas desulfurization requirements and process economics dictates that this desulfurization be performed near the temperature of the gasification off-gas. The most advanced hot gas desulfurization technology today is based on the zinc ferrite sorbent which has several shortcomings such as zinc loss by evaporation, and incomplete regeneration due to sulfate formation. The objective of this study is to develop an improved sorbent which can reduce H2S levels to 1 ppmv or less, which can stabilize zinc, and produce economically recoverable amounts of elemental sulfur during regeneration. For this purpose, the desulfurization performance.of sorbents prepared by the addition of various amounts of V205 to the zinc ferrite sorbent is investigated. Preliminary experiments show that the sorbent containing about 4.8 mass % vanadium shows a superior desulfurization performance compared to zinc ferrite. Addition of vanadium suppresses residual sulfate formation and possibly zinc evaporation. significant quantities of elemental sulfur were observed after the regeneration of vanadium containing sorbents.

Available in PDF, EPUB and Kindle. Book excerpt: Economic and environmental requirements for advanced power generating systems demand the removal of corrosive and other sulfurous compounds from hot coal gas. After a brief account of the world energy resources and an overview of clean coal technologies, a review of regenerable metal oxide sorbents for cleaning the hot gas is provided. Zinc oxide, copper oxide, calcium oxide, manganese oxide based as well as supported and mixed metal oxide sorbents are treated. Performance analysis of these sorbents, effects of various parameters on the desulfurization efficiency, kinetics of sulfidation and regeneration reactions, sulfiding and regeneration mechanisms are discussed. Two chapters present recent results in the direct production of elemental sulfur from regeneration or SO2-rich gases.

Book Synopsis Development of Advanced Hot-gas Desulfurization Processes by :
Download or read book Development of Advanced Hot-gas Desulfurization Processes written by and published by . This book was released on 1999 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced integrated gasification combined cycle (IGCC) power plants nearing completion, such as Sierra-Pacific, employ a circulating fluidized-bed (transport) reactor hot-gas desulfurization (HGD) process that uses 70-180 [mu]m average particle size (aps) zinc-based mixed-metal oxide sorbent for removing H2S from coal gas down to less than 20 ppmv. The sorbent undergoes cycles of absorption (sulfidation) and air regeneration. The key barrier issues associated with a fluidized-bed HGD process are chemical degradation, physical attrition, high regeneration light-off (initiation) temperature, and high cost of the sorbent. Another inherent complication in all air-regeneration-based HGD processes is the disposal of the problematic dilute SO2 containing regeneration tail-gas. Direct Sulfur Recovery Process (DSRP), a leading first generation technology, efficiently reduces this SO2 to desirable elemental sulfur, but requires the use of 1-3 % of the coal gas, thus resulting in an energy penalty to the plant. Advanced second-generation processes are under development that can reduce this energy penalty by modifying the sorbent so that it could be directly regenerated to elemental sulfur. The objective of this research is to support the near and long term DOE efforts to commercialize the IGCC-HGD process technology. Specifically we aim to develop: optimized low-cost sorbent materials with 70-80 [mu]m average aps meeting all Sierra specs; attrition resistant sorbents with 170 [mu]m aps that allow greater flexibility in the choice of the type of fluidized-bed reactor e.g. they allow increased throughput in a bubbling-bed reactor; and modified fluidizable sorbent materials that can be regenerated to produce elemental sulfur directly with minimal or no use of coal gas The effort during the reporting period has been devoted to development of an advanced hot-gas process that can eliminate the problematic SO2 tail gas and yield elemental sulfur directly using a sorbent containing a combination of zinc and iron oxides.

Download or read book Simultaneous Hot Gas Desulfurization and Improved Filtration written by and published by . This book was released on 1996 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research suggests the use of waste metal oxide materials for the removal of sulfur in hot gas streams as an alternative to either traditional calcium based sorbents, or regenerable metal oxide sorbents. When classified to a desired particle size and injected into a high temperature coal utilization process, such a ''once-through'' sorbent can effectively remove sulfur and simultaneously increase the permeability of dust collected at a downstream ceramic filter station in a highly cost effective manner. There is considerable technical and economic promise in the use of waste metal oxides for the removal of sulfur dioxide (SO2) and hydrogen sulfide (H2S) from coal gas streams containing these components, based upon results from tests under controlled laboratory conditions. Several waste metal oxides, including the oxides of iron, tin, and zinc, have been evaluated both individually and in combination to assess their capacity for sulfur capture in both oxidizing and reducing atmospheres. Additionally, inert materials such as silica sand as well as more traditional materials such as dolomite and limestone, were evaluated as sorbents under identical test conditions to serve as reference data. Efforts also explored the overall domestic availability of the best performing waste metal oxide sorbents, taking into account their geographic distributions, intrinsic value, etc. to provide the groundwork for commercial implementation of a low cost, highly effective sulfur sorbent for eventual use in both coal combustion and coal gasification processes. Recent elevated temperature thermogravimetric analysis (TGA) testing of these samples, performed at the Institute of Gas Technology (IGT), has further confirmed the trends in sulfur affinity which were observed in the preliminary testing.
