Available in PDF, EPUB and Kindle. Book excerpt: Externally fired rotary kilns were evaluated for use as regeneration reactors for the spent limestone sorbent from a fluid-bed combustor. Coke and spent sorbent containing approximately 8 wt % sulfur were reacted at temperatures between 960 and 1060/sup 0/C in two laboratory-scale externally fired rotary kilns to produce lime sorbent suitable for reuse, and concentrated SO/sub 2/. It was possible to achieve a high percent of sorbent regeneration, but the SO/sub 2/ concentration in the off-gas was low. Different operating conditions were required to produce a higher concentration of SO/sub 2/ in the off-gas, and under these conditions, the percent of sorbent regeneration was low. Two empirical equations and the shrinking-core reaction-rate model were examined for application to the experimentally determined kinetic data. The shrinking-core model appeared to fit the data better than the empirical equations, and could be a useful predictor of the conversion of sulfated limestone and of the SO/sub 2/ concentration in the off-gas from a rotary-kiln regenerator. The materials used in the construction of one of the laboratory kilns were typical of commercially available production-size rotary kilns that are externally fired. However, the materials of construction were not sufficiently durable to withstand the high SO/sub 2/ concentrations and high temperatures involved in this reaction.

Available in PDF, EPUB and Kindle. Book excerpt: These studies are concerned with the development of processes for the regeneration of sulfated limestone from fluidized-bed combustors. The results of cyclic combustion/regeneration experiments on three limestones are reported. The reactivity of a low-reactivity limestone, Germany Valley, did not change significantly during cyclic combustion/regeneration. Studies of a high-reactivity limestone, Greer, at lower regeneration temperatures (1050/sup 0/C) indicated an apparently better performance than at 1100/sup 0/C. The sorbent utilization of type 2203 limestone in a three-cycle experiment was similar to that of Greer. The results of studies of a process for the recovery of elemental sulfur from SO/sub 2/ involving reaction with fly ash or coal ash-coal combinations are reported. The residual carbon in the fly ash was found to be an effective reductant for the SO/sub 2/ and high-purity sulfur was obtained. Regeneration of spent limestone sorbent in externally fired rotary kilns was accomplished, but only under conditions that resulted in rapid attack of the kiln materials by SO/sub 2.

Available in PDF, EPUB and Kindle. Book excerpt: This book approaches the energy science sub-field carbon capture with an interdisciplinary discussion based upon fundamental chemical concepts ranging from thermodynamics, combustion, kinetics, mass transfer, material properties, and the relationship between the chemistry and process of carbon capture technologies. Energy science itself is a broad field that spans many disciplines -- policy, mathematics, physical chemistry, chemical engineering, geology, materials science and mineralogy -- and the author has selected the material, as well as end-of-chapter problems and policy discussions, that provide the necessary tools to interested students.
