Since the middle of the last century, discussion about the operation of discontinuous fractionation to meet multifarious goals, such as product purity and recovery rate, by monitoring process variables including reflux or/and heat duty, is been on. The engineering practice showed intolerable events to occur; hereof the operation must be supervised, which makes it difficult to be in agreement with the batch distillation objectives. Hence, to uphold the effectuation of new operating policies into the industrial “know-how” techniques, different optimal control strategies can be conceived. The objective of this work is to offer a literature survey on the investigations of optimal control functioning for selected simple distillation column configurations employed in batch/semibatch distillation of homogeneous/reactive mixtures, as well as the approaches used in this regard. Available optimal control schemes have been reviewed in detail, emphasizing its major assets.

分馏调查：间歇式和半间歇式蒸馏的最佳控制

自上世纪中叶以来，关于通过监测包括回流或/和热负荷在内的工艺变量来满足多种目标（例如产品纯度和回收率）的不连续分馏操作的讨论一直在进行。工程实践表明发生了无法容忍的事件；其操作必须有监督，难以与分批蒸馏目标一致。因此，为了支持将新的运营政策应用到工业“专有技术”技术中，可以构想不同的最优控制策略。这项工作的目的是提供文献调查，研究用于均质/反应混合物的分批/半分批蒸馏的选定简单蒸馏塔配置的最佳控制功能研究，以及在这方面使用的方法。对可用的最优控制方案进行了详细审查，强调了其主要资产。
