The longitudinal dispersion coefficient of droplet phase was measured in 6.6 and 12.2 cm i.d. single- and multistage bubble columns where kerosene was dispersed by air and water flows. Experimental residence time distribution curves of the droplet phase were analyzed by a newly proposed dispersion model, which included the back-flow of droplets through perforated baffle plates and the exchange of dye concentration in the droplet phase at the perforated baffle plates due to dispersion-coalescence phenomena. The exchange coefficient of the dye concentration was obtained by comparing experimental residence time distribution curves with the theoretical ones. The overall longitudinal dispersion coefficient of the droplet phase in multi-stage bubble columns was satisfactorily simulated by the present model, parameters of which were all given as experimental equations. The mean gas holdup in the 12.2cm i.d. column for air-water-solvent (n-hexane, terpentine oil and a mixed oil) systems was increased about 20% by installation of perforated baffl plates.
