Description:
The report gives results of an experimental determination of fine particle collection in mobile bed scrubbers. Particle collection efficiency increased greatly as the gas-phase pressure drop increased. With no water vapor condensation, the performance capability of a mobile bed scrubber is less than that of a gas-atomized spray scrubber with the same pressure drop. Compared to packed bed and sieve plate scrubbers, the mobile bed scrubber has better efficiency when the pressure drop is above 20 cm W.C. Limestone in the scrubber liquid has no effect on particle collection. When the mobile bed scrubber was used as a flux force/condensation (FF/C) scrubber, it had better performance characteristics than sieve plate and spray scrubbers with condensation. However, its capability is inferior to a FF/C system consisting of a condenser and venturi scrubber. Design equations reported in the literature are inadequate to predict the collection efficiency and pressure drop of the mobile bed scrubber. The study developed new correlations to predict particle collection and pressure drop.
