| Abstract: | Experiments and studies were carried out on axial backmixing in a gas agitated extractor with air-water-kerosene system static mixer being installed in, in which water was continuous phase, kerosene was dispersed phase and air was used as agitation. The axial dispersion coefficient of the continuous phase and the dispersed phase were measured respectively. The mass transfer coefficient was calculated by using axial dispersion model. The results were compared with that of the piston flowing model. Empirical correlation describing the mass transfer coefficient was obtained. |
