Cost of controlling directly emitted acidic emissions from major industrial sources. Final report, February 1985-August 1986

This 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 SO/sub 2/ is simultaneously emitted with the acidic materials, controls were selected that removed both SO/sub 2/ and the acidic materials. Cost-effectiveness was considerably better for the combined (SO/sub 2/ 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.
