The report gives results of estimates, using a model plant approach, of costs for retrofitting selected acidic emission control systems to utility and industrial boilers, Claus sulfur recovery plants, catalytic cracking units, primary copper smelters, coke oven plants, primary aluminum smelters, and municipal solid waste incinerators. Cost-effectiveness (defined as the unit annual cost for removing acidic materials) of each control system was calculated based on the anticipated performance of the system. If SO2 is simultaneously emitted with the acidic materials, controls were selected which removed both SO2 and the acidic materials. Cost-effectiveness was considerably better for the combined (SO2 plus acidic material) removal systems. Because of a need for performance data on acidic emissions control systems, it would be desirable if research could be conducted on removing acid sulfates and nitrates by existing gaseous and particulate control systems.
