Abstract:A method for simultaneous evaluation of axial mixing coefficients and True -HTU of the extraction column is suggested. By this method the measured steady state concentration profiles of the two phases in the column are fitted with the optimal technique based on the diffusion model in the form given by Miyauchi and Vermeulen.This method has been successfully applied in the study of the performance of mass transfer of the system HNO3 (aq. )-30% TBP (kerosene as diluent) in a pulsed sieve plate extraction column.
