چکیده

Abstract

Pulsed sieve-plate extraction column is the very important equipment in nuclear spent fuel reprocessing. Study of the mass  transfer  characteristics  in  the  extraction  column  under  different  operating  conditions  is  beneficial  to  the  optimization and scale-up of the columns. The experiments were carried out in the system of 30% tributy1 phosphate (TBP) in kerosene-nitric acid-deionized water in the standard pulsed sieve-plate column. The axial dispersion model (ADM) coupled with the steady-state concentration profiles was used to calculate the overall volumetric mass transfer coefficient Koxa. The influence of the continuous and dispersed phase superficial velocities, pulse intensity and flow rate on the Koxa had been analyzed. It shows that with the increase of the continuous and dispersed phase superficial velocities and flow ratio, Koxa increases first and then decreases; but it increases when the pulse intensity increases. Finally,  an  empirical  correlation  had  been  concluded  to  predict  the  mass  transfer  performance  in  the  extraction  column.
