A computer program has been developed for optimization and modelling of counter–current solvent extraction processes. The distribution between the phases is calculated by either D-ratio functions or by a novel kinetic model for the transfer between the phases. The kinetic model is important to use when slow extraction kinetics yields D-ratios far from equilibrium. Transfer rate data was investigated in a single stage centrifugal contactor, modified for internal recirculation of the phases. Using this methodology a demonstration process for the recovery of minor actinides in a counter–current centrifugal contactor system using CyMe4-BTBP was modelled with excellent agreement towards the experimental values.
