Abstract

Studies have been carried out on the axial dispersion in the continuous phase and the hold-up of dispersed phase in a rotating screen-blade extraction column, by employing an axial dispersion model. Experiments on both single and two phase operations have been conducted with the plate spacing, the mesh size, the impeller speed (RPM), and the superficial velocities as the system parameters. By regression analysis of experimental data, empirical equations correlating the dispersion coefficients and the fractional hold-up of dispersed phase with the system parameters were obtained.
