基于Python的化工流程优化系统开发

文章导读

摘要作为一种通用化工流程模拟系统,Aspen Plus已广泛应用于化工流程的模拟、设计与优化。随着人们对复杂流程优化的需求越来越多,Aspen Plus自带的灵敏度分析已经不能满足需要,将Aspen Plus与优化算法进行集成,用于求解复杂优化问题有其必要。在Python环境下实现了对Aspen Plus流程模拟的控制和数据传递,在此基础上开发了一套流程优化系统,可将各种优化算法方便地集成在一起,用于解决不同特点的优化问题。采用坐标轮换法以年度总费用TAC(Total Annual Cost)为目标函数,对甲醇-丙酮共沸体系的双塔变压精馏进行优化,灵活实现了对不同变量、不同顺序的优化,均取得预期效果,提高了工艺开发效率。

Abstract： As a general chemical process simulation system, Aspen Plus has been widely used in simulation, design and optimization of chemical processes. As the need for complex process optimization increases, Aspen Plus’s built-in sensitivity analysis is no longer sufficient. Therefore, it is necessary to integrate Aspen Plus with optimization algorithms for solving complex optimization problems. In the Python environment, the control and data transmission of the Aspen Plus process simulation are realized, and a process optimization system is developed on this basis, which can easily integrate various optimization algorithms to solve optimization problems with different characteristics. Using theunivariate search technique to optimize the double-column variable pressure distillation of methanol-acetone azeotropic system with the annual total cost as the target function, the optimization of different variables and different sequences is flexibly realized, and the expected effects are achieved and the process development efficiency is improved.
