Operation and design of liquid analogue simulators for finding optimal zone lengths for maximum separation efficiency in multipass zone-refining processes is simulated. Performance of those liquid analogue simulators with optimal zone lengths for all passes and their corresponding maximum fraction of solute removals for up to 10 passes were determined with distribution coefficients k and pass number n as parameters. The simulation results indicated that the optimal zone lengths for all passes increase with the distribution coefficient but decrease with the pass number. The proposed multipass liquid analogue simulators closely correspond to that of analytical solutions. Moreover, the more total ingot tubes are employed, the more accurate the measurement will be.
