Table 49 shows under stable conditions, the extraction O: A is 4.5: 1, the washing O: A is 56: 1, and the strip is 15: 1. The recycled strip is 0.25: 1, which is within the set operating range. The experimental data of simulated counter current extraction is in good agreement with the experimental data from batch operation. The expected results can be achieved by adjusting the flow rate and phase ratio of each phase.
