Book Synopsis Dry Scrubbing Technologies for Flue Gas Desulfurization by : Barbara Toole-O'Neil
Download or read book Dry Scrubbing Technologies for Flue Gas Desulfurization written by Barbara Toole-O'Neil and published by Springer Science & Business Media. This book was released on 1998-11-30 with total page 912 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dry sulfurization processes offer the significant advantages of low capital and low operating costs when compared to wet desulfurization. They hold great potential for the economical reduction of sulfur emissions from power utilities that use high-sulfur coal. Dry Scrubbing Technologies for Flue Gas Desulfurization represents a body of research that was sponsored by the State of Ohio's Coal Development Office for the development of technologies that use coal in an economic, environmentally-sound manner. One of the project's major goals was the development of dry, calcium-based sorption processes for removing sulfur dioxide from the combustion gases produced by high-sulfur coal. Dry Scrubbing Technologies for Flue Gas Desulfurization highlights a number of fundamental research findings that have had a significant and lasting impact in terms of scientific understanding. For example, the experimental investigation of the upper-furnace sulfur capture obtained time-resolved kinetic data in less than 100 millisecond time-scales for the first time ever, thereby revealing the true nature of the ultra-fast and overlapping phenomena. This was accomplished through the development of a unique entrained flow reactor system. The authors also identify a number of important areas for future research, including reaction mechanisms, sorbent material, transport effects, modeling, and process development. Dry Scrubbing Technologies for Flue Gas Desulfurization will appeal to both chemical and environmental engineers who examine different ways touse coal in a more environmentally benign manner. It will make an essential reference for air pollution control researchers from coal, lime, cement, and utility industries; for government policy-makers and environmental regulatory agencies; and for those who teach graduate courses in environmental issues, pollution control technologies, and environmental policy.

This book was released on 1993 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this investigation is to evaluate two novel copper-based sorbents (i.e. copper-chromium and copper-cerium) for their effectiveness in removing hydrogen sulfide from fuel gas in the temperature range of 650° to 850°C. New sorbent compositions from the selected Cu-Cr-O and Cu-Ce-O binary oxides were prepared and characterized by BET N2-desorption surface area measurement following various calcination/time-temperature exposures. The general trends reported last quarter (on 11 different compositions) were validated this quarter in that both binary oxides lose surface area as the amount of CuO is increased. Time-resolved sulfidation tests were conducted at 850°C using the equimolar CuO. Cr2O3 composition. The two selected binary oxides prepared in larger qauntities (for testing in a two-inch reactor) have physical properties typical of the sorbents prepared in past programs. Two multicycle desulfurization tests, conducted this quarter on the Cu-Ce-O sorbent at 850°C, using a feed gas containing 5000 ppm H2S, 10 vol % H2 and 10 vol % H2O at a space velocity (STP) of 2000 h−1, demonstrated high sulfur removal efficiency for the first one or two cycles, and a significant reduction in efficiency in the following cycles.

This book was released on 1993 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this investigation is to evaluate two novel copper-based sorbents (i.e. copper-chromium and copper-cerium) for their effectiveness in removing hydrogen sulfide from fuel gas in the temperature range of 650° to 850°C. In this program, structural and kinetic studies are conducted on various compositions of the two selected copper-based sorbents to determine the optimum sorbent composition. The effect of operating conditions on the performance of the sorbents alone with the stability and regenerability of the selected sorbents in successive sulfidation/regeneration operation are determined. Parametric multicycle desulfurization tests were conducted this quarter in a bench-scale (5-cm-diameter) quartz reactor at one atmosphere using the CuCr2O4 and CuO/CeO2 sorbents. The parameters studied included temperature, space velocity, and feed gas composition. Both sorbents were able to reduce the H2S concentration of the reactor feed gas to

This book was released on 1993 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this investigation is to evaluate two novel copper-based sorbents, namely Cu-Cr and Cu-Ce, for their effectiveness in removing hydrogen sulfide from fuel gas in the temperature range of 650 to 850 C. Such high temperatures will be required for the new generation of gas turbines in Integrated Gasification Combined Cycle systems. Structural and kinetic studies were conducted on various compositions of the two Cu-based sorbents to determine the optimum sorbent composition. The effect to operating conditions on the performance of the sorbents along with the stability and regenerability of the selected sorbents in successive sulfidation/regeneration operation were determined. Overall, the CuO-lean binaries (with Cr2O3 or CeO2) may benefit the H2S breakthrough levels. While this is at the expense of sulfur capacity for the Cu-Cr-O sorbents, it may not affect the capacity of the Cu-Ce-O sorbents. Parametric multicycle desulfurization tests were conducted in a bench-scale quartz reactor at one atmosphere using the CuCr2O4 and CuO-CeO2 sorbents. The parameters studied included temperature, space velocity, and feed gas composition. Both sorbents were able to reduce the H2S concentration of the reactor feed gas from 5,000 ppmv to less than 1 ppmv to 10 ppmv at 750 to 850 C. Both sorbents were found to consume H2 and produce SO2 during the initial stages of sulfidation. Analysis of partially sulfided samples identified predominantly Cu metal, the additive oxide and small amounts of oxidic copper. For the Cu-Cr-O sorbents, the latter is apparently sufficient to keep the H2S pre-breakthrough levels as low as has been reported in this work. For the Cu-Ce-O sorbents, in which very little or no oxidic copper remained, the low H2S levels may be due to the participation of CeO2, whose sulfidation is promoted by Cu.

Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this study was to determine the effectiveness of the copper-chromite sorbent (developed in previous ICCI-funded projects) for longer duration application under optimum conditions in the temperature range of 550°-650°C to minimize sorbent reduction and degradation during the cyclic process. Three (3) formulations of attrition resistant granules of the copper chromite sorbent (i.e., CuCr-10, CuCr-21, and CuCr-29) as well as one (1) copper chromite sorbent in pellet form (i.e., CuCr-36) were selected for cyclic desulfurization tests. The desulfurization and regeneration capabilities of the selected formulations as well as the effects of operating parameters were determined, to identify the {open_quotes}best{close_quotes} sorbent formulation and the optimum operating conditions. The durability of the {open_quotes}best{close_quotes} sorbent formulation was determined in {open_quotes}long-term{close_quotes} multicycle tests conducted at the optimum operating conditions. The attrition resistance of the selected formulations were determined and compared with those of other sorbents, including a limestone, a dolomite, and a commercial zinc titanate sorbent. The results obtained in this study indicate that, the CuCr-29 sorbent has excellent attrition resistance and desulfurization performance, which are far superior to the commercial zinc titanate sorbents. The optimum desulfurization temperature in terms of sorbent efficiency and utilization appears to be about 600°C. Sorbent regeneration at 750°C ensured complete conversion of the copper sulfide to oxide without sulfate formation or reactivity deterioration in subsequent cycles.
