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 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.
