AEROSOL FORMATION BY SPONTANEOUS PHASE-TR ANSITIONS IN ABSORPTION ANDCONDENSATION PROCESSES

Formation of aerosols by spontaneous condensation or desublimation in condensers or absorbers often causes serious problems in industrial pr ocesses. The fine aerosol particles, formed under special operating co nditions, remain suspended in gases and are carried over into downstre am stages or lead to high pollutant concentrations in the exhaust gas. The present paper describe under what conditions aerosols are formed. The characteristic behaviour of aerosols is discussed with the aid of experiments and computer simulation.
