A comparative assessment of flue gas treatment processes part i—status and design basis

Abstract

The developmental status, projected costs, and environmental effects of 14 flue gas treatment processes are compared on a common basis in two consecutive issues of JAPCA. Part I summarizes the background and study basis and Part II compares environmental impact and relative costs. Each process is assumed to be associated with a grass roots installation that includes a modern 800 MW power plant burning Illinois No. 6 coal. Also considered is the effectiveness of these processes to control particulate matter, NOx, trace inorganics, and polyorganic matter. The processes are divided into those operating once-through (Limestone, Lime, Limestone and Lime, Dual-Alkali), and with regeneration (Magnesia, Wellman-Lord, Citrate, Aqueous Carbonate, IFP-Catalytic Inc., Copper-Dry Bed, and Carbon-Dry Bed). Also analyzed are NOx control processes that are compatible with scrubbers or dry processes, and include the Exxon Thermal DeNOx, Ozone NO Oxidation, and Copper and Carbon-Dry Bed. © 1981 Air & Waste Management Association.
