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.

摘要： 本文提出了一种根据扩散模型用最优化方法拟合浓度剖面的计算方法,可以在有传质情况下,较准确地由实验测定的稳态浓度剖面,同时求得轴向混合系数和扣除了轴向混合影响后的“真实”质单元高度.并已成功地用于脉冲筛板萃取柱的传质性能研究中.
