Abstract: The characteristics of the packed extraction column as well as the selection and development of packing in the packed extraction column were reviewed in this paper. The industrial application of the part of the packing was exemplified. Various theoretical models and methods used to study the mass transfer and fluid dynamics characteristics of the packed extraction column were described. The research methods of the packed extraction column consist of experimental method, empirical formula and simulation method. The droplet diameter, the dispersed phase volume fraction, the flooding velocity and slip speed by experiment can be obtained accurately, while detailed microscopic information of the flow field, temperature field and concentration field through computer simulation can be acquired. It can be foreseen that the combination of experimental method, empirical formula, computer simulation will become an effective methods to solve the problems of mass transfer and fluid dynamics of the packed extraction column.
