THE DYNAMICS OF AEROSOLS IN CONDENSATIONAL SCRUBBERS

A mathematical model for the simulation of the dynamics of aerosol cha nge in condensational scrubbers and scrubbing condensers is proposed. The model is applicable for packed column gas/liquid contact when plug flow can be assumed. The model is compared with experimental data for particle removal in a pilot plant condensational scrubber. The model can satisfactorily predict particle growth and particle deposition by diffusional, convective and inertial mechanisms for a wide range of co nditions. The parameters of principal importance for the model precisi on are identified and a procedure for their estimation is proposed. Th e behaviour of scrubbers and condensers for some important technical a pplications is demonstrated by model simulations. (C) 1997 Elsevier Sc ience Ltd.
