The objective of this four-task program was to develop smaller, less expensive scrubbers while maintaining or improving scrubber efficiency and reliability. The development included (1) building a scrubber test facility suitable for testing contract-developed and future scrubber systems, (2) develop and test four fibrous-bed panels and two water droplet eliminators to reduce scrubber size and clogging, (3) fabricate and test two fibrous bed panels for use with the Bureau of Mines rotating, flooded-bed scrubber system, and (4) develop and test water-powered scrubber and recycle water systems for use at low water pressures. Tests revealed that the standard water droplet eliminator and the 20 double-layer fibrous-bed panels were the best choices for scrubber improvement. Based on clogging and pressure drop tests, it was recommended using 16 double layers of knitted wire mesh in the rotating scrubber.
