• The Purex process in mixer-settlers<SUP>(1)(3)</SUP> has been modelled and simulated by the non-equilibrium extraction model that employs a defined Murphree stage efficiency<SUP>(4)</SUP> as the fitting parameter for simulation. However, Murphree stage efficiency can not be applied as it is to the chemical reaction system of the Purex process, because Murphree stage efficiency is defined for the mass distribution of non-chemical reaction system.<BR>In the present study, a partial equilibrium model was presented that expresses an effective mass distribution between aqueous and organic phases for chemical reaction system with a new stage efficiency ; a complete mixing fraction. And the significance of the new stage efficiency was examined comparing with Murphree stage efficiency.
