This book was released on 1994 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to obtain data on the rates of reaction between, hydrogen sulfide (H2S) and uncalcined calcium-based sorbents under operating conditions relevant to first stage (carbonizer) of Advanced Two-Stage Pressurized Fluidized-Bed Combustors (PFBC). In these systems the CO2 partial pressure in the first stage generally exceeds the equilibrium value for calcium carbonate decomposition. Therefore, removal of sulfur compounds takes place through the reaction between H2S and calcium carbonate. To achieve this objective the rates of reaction between hydrogen sulfide and uncalcined calcium-based sorbents will be determined by conducting tests in pressurized thermogravimetric analyzer (TGA) and high-pressure/high-temperature fluidized-bed reactor (HPTR) units. The effects of sorbent type, sorbent particle size, reactor temperature and pressure, and CO2 and H2S partial pressures on the sulfidation reaction rate will be determined. During this quarter, the high-pressure thermogravimetric analyzer (HPTGA) unit was installed and the shakedown process was completed. Several tests were conducted in the HPTGA unit to establish the operating procedure and the repeatability of the experimental results. Sulfidation by conducting the baseline sulfidation tests. The results are currently being analyzed.

During this quarter a series of sulfidation tests were conducted in the high-pressure high-temperature thermogravimetric analyzer (HPTGA unit) using limestone and dolomite. The results suggest that half-calcined dolomite is much more reactive than uncalcined limestone. Also, temperature in the range of 800 to 950 C did not significantly affect the sulfidation reaction rates for both limestone and dolomite.

This book was released on 1996 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to obtain data on the rates and the extent of sulfation reactions involving partially sulfided calcium-based sorbents, and oxygen as well as sulfur dioxide, at operating conditions closely simulating those prevailing in the second stage (combustor) of Advanced Two-Stage Pressurized Fluidized-Bed Combustors (PFBC). In these systems the CO2 partial pressure generally exceeds the equilibrium value for calcium carbonate decomposition. Therefore, calcium sulfate is produced through the reactions between SO2 and calcium carbonate as well as the reaction between calcium sulfide and oxygen. To achieve this objective, the rates of reaction involving SO2 and oxygen (gaseous reactant); and calcium sulfide and calcium carbonate (solid reactants), will be determined by conducting tests in a pressurized thermogravimetric analyzer (HPTGA) unit. The effects of sorbent type, sorbent particle size, reactor temperature and pressure; and O2 as well as SO2 partial pressures on the sulfation reactions rate will be determined. During this quarter, samples of the selected limestone and dolomite, sulfided in the fluidized-bed reactor during last quarter, were analyzed. The extent of sulfidation in these samples was in the range of 20 to 50%, which represent carbonizer discharge material at different operating conditions. The high pressure thermogravimetric analyzer (BPTGA) unit has been modified and a new pressure control system was installed to eliminate pressure fluctuation during the sulfation tests.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The RFB provides an option for coal combustion systems by separating the desulfurization of hot combustion product gases from the combustion process itself. Fluid-bed combustors conventionally combine the two processes and, as a result, the rapid combustion process is carried out in equipment whose design is dominated by the requirements of the slower and temperature-specific desulfurization process. Neither process can be optimized and, in fact, the specifics of the combined reaction chemistry are unclear. Separation of the processes allows consideration of alternative combustors, sorbents, and sorption devices. The RFB desulfurizer has the potential to reduce equipment sizes through improvements in reaction rates and sorbent utilization. Additionally, separation of the combustion and sorption reactions leads to a relatively clean separation of ash and spent sorbent allowing for better waste utilization or disposal. Several process advantages are associated with the use of the rotating rather than the stationary fluidized bed for sulfur removal. These stem primarily from two characteristics inherent in the multi-g system. First, smaller particles can be retained in the fluidized bed, with the following three important advantages: (a) Smaller particles will contribute to higher sulfation rates because of increased surface area; the better rates will lead to a shorter gas residence time; (b) Greater sorbent utilization will occur. Sulfation causes the buildup of a product layer on the outside of the sorbent particles, which corresponds to a higher fraction of sorbent utilization in the case of a small particle than with a larger particle; (c) The low gas velocities possible in the fluidization of small particles will permit relatively long residence times.

Available in PDF, EPUB and Kindle. Book excerpt: Alkali metal or alkaline earth metal oxides are impregnated within refractory support material such as alumina and introduced into a fluidized-bed process for the combustion of coal. Sulfur dioxide produced during combustion reacts with the metal oxide to form metal sulfates within the porous support material. The support material is removed from the process and the metal sulfate regenerated to metal oxide by chemical reduction. Suitable pore sizes are originally developed within the support material by heat-treating to accommodate both the sulfation and regeneration while still maintaining good particle strength.

During this quarter, samples of the selected limestone and dolomite were sulfided in the fluidized-bed reactor. These tests were conducted in both calcining and non-calcining operating conditions to produce partially-sulfided sorbents containing calcium oxide and calcium carbonate, respectively. These samples which represent the carbonizer discharge material, will be used as the feed material in the sulfation tests to be conducted in the HPTGA unit during the next quarter.

Book excerpt: The objective of this study is to obtain data on the rates and the extent of sulfation reactions involving partially sulfided calcium-based sorbents, and oxygen as well as sulfur dioxide, at operating conditions closely simulating those prevailing in the second stage (combustor) of Advanced Two-Stage Pressurized Fluidized-Bed Combustors.

To achieve this objective, the rates of reaction involving SO2 and oxygen, calcium sulfide and calcium carbonate will be determined by conducting tests in a pressurized thermogravimetric analyzer unit. The sulfate tests conducted during this quarter, focused on the determination of the rate of sulfation reaction involving partially sulfided half-calcined dolomite and oxygen. The test parameters included CO2 and O2 concentrations, reaction temperature and pressure, as well as the sorbent particle size. The results obtained during this quarter suggest that the rate of sulfation reaction involving partially sulfided half-calcined dolomite and oxygen is very fast at temperatures above 850 C which rapidly increases with increasing temperature, achieving more than 85% conversion in less than a few minutes. The reaction appears to continue to completion, however, above 85% conversion, the rate of reaction appears to be low, requiring long residence time to reach complete conversion.
