Profiles In Flue Gas Desulfurization

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.

Dr. Richard R. Lunt has over 25 years experience in process research, development, design and implementation with United Engineers and Constructors (now Raytheon), and Arthur D. Little, Inc., where he is currently a principal in the environmental science and technology practice. A B.S. chemistry graduate from Colgate University, who hold M.S. and Ph.D. degrees in chemical engineering from Columbia University, Lunt has worked on the design of more than a dozen FGD systems, has coordinated process research and development for six new FGD technologies, and holds three patents, two in the development of SO₂ control technology. Lunt is a Registered Professional Engineer in three states, and a member of the American Institute of Chemical Engineers and Sigma Xi.

John D. “Jack” Cunic is a senior staff engineer with ExxonMobil Research and Engineering Company in Florham Park, New Jersey, where his responsibilities include heading the Air Environmental Applications Group responsible for conducting in-depth screening studies and identifying required air pollution control equipment. A graduate of Worcester Polytechnic Institute, where he obtained both his B.S. and M.S. degrees in chemical engineering, Cunic conducted the study which identified Exxon’s Wet Gas Scrubbing system for FCCU’s as a viable alternative, and provided technical startup assistance for the first commercial unit in 1974. He is a member of AIChE,AWMA, and API, and has authored numerous papers on scrubbing, precipitators, and flue gas desulfurization systems.
