摘　　要：间歇精馏是一种重要的化工分离技术,在处理小批量、多组分生产中具有显著优势。为提高间歇精馏性能,研究者提出了多种间歇精馏过程强化结构,如中间储罐间歇精馏塔(MVBDC)、隔板间歇精馏塔(DWBDC)等。本文建立了传统间歇精馏塔(BDC)、MVBDC、DWBDC三种典型结构的动态仿真模型,搭建了控制系统,并通过贝叶斯优化算法对三种间歇精馏的操作变量进行了严格优化,通过分析严格优化后的结果对比了三种精馏过程结构的优劣。结果表明,DWBDC具有最短的操作时间和最好的经济效益,是一种优越的间歇精馏过程强化结构。Batch distillation is an important chemical separation technology that has significant advantages in processing small batches and multi-component production.To enhance the performance of batch distillation,researchers have proposed various batch distillation intensification structures,such as middle vessel batch distillation column(MVBDC)and dividing wall batch distillation column(DWBDC).This paper establishes dynamic simulation models for three typical structures:conventional batch distillation column(BDC),MVBDC,and DWBDC.It also establishes control systems and strictly optimizes the operational variables of the three batch distillation processes using Bayesian optimization algorithms.The results of strict optimization are compared in order to evaluate the advantages and disadvantages of these three structures.The findings indicate that the DWBDC has the shortest operating time and the best economic benefits,making it a superior batch distillation structure.
