The report gives results of a feasibility study of flux force/condensation (FF/C) scrubbing for fine particle (smaller than 2.0 micron diameter) control. FF/C scrubbing includes effects of diffusionphoresis, Stephan flow, thermophoresis, and particle growth due to condensation of water vapor; it is not restricted to a specific scrubber configuration. Experimental determination of sub-micron particle collection efficiency in a bench-scale, sieve-plate FF/C scrubber validated the mathematical model developed in the analytical phase. Process designs and cost estimates for applying FF/C scrubbing to two fine particle pollution sources demonstrated its technical and economic feasibility. FF/C scrubbing is an attractive control method for fine particles when high efficiency is required and when the gas is hot enough to evaporate the necessary water vapor. Further development of FF/C scrubbing is clearly warranted. (Modified author abstract)
