While the dividing wall columns for continuous distillations have become quite popular, we present the first detailed analysis of a dividing wall column for batch distillation. For a dividing wall side stripper batch distillation column, we present an operating sequence and its associated mathematical model. Since there are many operating parameter combinations possible for this column, selecting the right operating parameters according to product specifications is presented as an optimization problem. This new configuration's performance is compared with the conventional batch rectifier and the middle vessel columns using two case studies related to the separation of a ternary mixture. The new batch dividing wall column performance is significantly better than the rectifier or the middle vessel column. As the purity specifications increase, the percentage improvement in profit due to the batch dividing wall column compared to the rectifier and the middle vessel columns increases.

虽然用于连续蒸馏的分隔壁塔已变得非常流行，但我们提出了用于间歇蒸馏的分隔壁塔的第一个详细分析。对于分隔壁侧汽提塔间歇式蒸馏塔，我们提出了操作顺序及其相关的数学模型。由于此列可能有许多操作参数组合，因此提出根据产品规格选择正确的操作参数是一个优化问题。使用两个与三元混合物分离有关的案例研究，将该新配置的性能与常规的间歇式精馏塔和中间容器塔进行了比较。新的批量分隔壁塔性能明显优于精馏塔或中间容器塔。随着纯度规格的提高，
