Spray-dryer scrubbers for sulfur-dioxide removal from flue gases have been a developing technology for several years. Because spray-dryer scrubbers offer several potential advantages over wet scrubbing, they are attractive to the utility industry. Some of these advantages are: 1) a simpler waste-disposal problem, 2) higher energy efficiency, 3) lower water comsumption, 4) lower capital cost, 5) lower operating costs, 6) less exotic materials of construction, 7) simpler operation, and 8) ability to consume some plant waste water in the spray dryer. The paper provides a broad survey of the state of the art as it might be useful to electric utilitites using high-sulfur coal.
