In this study, it is assumed that the distilling is made with only one rectifier column with a reboiler of maximum capacity (UN) and a given volume (10 mol) of a mixture of cyclohexane-(n-heptane)-toluene is treated. The total number of stages chosen is a minimal number sufficient for separation (7 stages), and the same as the volume of the reboiler, is not a control variable. The purity specified for all the main cuts is 0.95, therefore every step of the multicomponent batch distillation is finished when the most volatile component reaches its specified purity in the accumulator and/or reboiler. The campaign contains two distillations in total, ie. the least volatile component is obtained in the reboiler after the second distillation. In contrast, the first/second, resp., component, is obtained in the first/second accumulator. The used policy is the optimal cyclic reflux policy obtained for a variable reflux ratio in the earlier paper (Stojkovic et al. ).
