Regenerable methods of flue gas desulfurization, which recycle the absorbent and diminish the waste disposal problem, have been developed. One method which substitutes a magnesia (MgO) slurry for the lime/limestone slurry has been under development for several years and commercial systems have been operated. The basic chemical reactions occurring in a magnesia scrubber are known. The magnesia is hydrated in the slurry and the SO/sub 2/ in the flue gas reacts to form magnesium sulfite. The magnesium sulfite formed can be dried and subsequently decomposed at higher temperature to yield MgO for recycle to the scrubber, and more concentrated SO/sub 2/ for sulfuric acid or sulfur production. Thus, the magnesia FGD system both reduces scrubber sludge disposal and provides for a saleable by-product. Significant advantages could be realized by combining spray absorption technology with the regenerable magnesia flue gas desulfurization system as shown on a simplified flow chart. The reduction in equipment, operation, and maintenance requirements, combined with a saleable by-product could result in significant savings in both capital and operating costs. Bench-scale experiments indicate that it is technically feasible to combine spray absorption with magnesia scrubbing to remove greater than 90% of the SO/sub 2/ from gas streams containing 0.1 to 1.0% SO/sub 2/ under controlled conditions. The resulting product will probably be a mixture of MgSO/sub 3/.3H/sub 2/O and MgSO/sub 3/.6H/sub 2/O, with the trihydrate predominating at higher temperatures and lower humidity, while the hexahydrate would be favored at lower temperatures and higher humidity. As previously demonstrated and verified by thermogravimetric analysis, the magnesium sulfite hydrates can be dehydrated and subsequently decomposed thermally to give MgO for recycle to the scrubber and a concentrated SO/sub 2/ gas stream which can be used for sulfuric acid or sulfur production.

As the need to control process emissions has increased, so have the number of FGD treatment and control strategies. The effectiveness of these treatments vary greatly, depending the types and levels of the materials, as well as the size of the facility. Profiles in Flue Gas Desulfurization will help engineers and managers identify the technologies that best fit their plant and/or processes. It’s a quick and easy reference to all “tail-end” SO2 control processes currently in commercial use or “on the brink,” providing an effective “snapshot” of where this technology stands in industry today. The technologies are divided into waste producing processes, where the end product is a “clean waste,” and byproduct processes, where the end product has market value. Each technology profile includes a schematic depicting its major equipment components and arrangement, laid out side-by-side with descriptive text on how the process works, where and how it is currently being utilized, its operational requirements, advantages and limitations for typical applications, and a brief list of principal suppliers.

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.
