The objective of this project is the pilot scale evaluation of SO/sub 2/ and NO/sub x/ removal from flue gas by means of a lime slurry spray dryer followed by electron beam treatment. Capital and operating costs of this technique have been determined and been shown to be cost effective. The pilot scale work will serve to verify the cost study assumptions and to provide design guidelines for commercial applications. The pilot scale system, consisting of a spray dryer, electron beam and fabric filter, will treat a flue gas slipstream from a 150 MW coal fired boiler. Parameters such as lime reactant rate and electron beam dosage will be varied, and SO/sub 2/ and NO/sub x/ removal will be monitored. It is expected that better than 90% removal of SO/sub 2/ and NO/sub x/ will be achieved with reasonable operating costs. 2 references, 10 figures, 1 table.
