Abstract

An economically optimal operation of batch diafiltration processes is studied. The processes are characterized by complex membrane transport models that adequately describe non-ideal membrane characteristics of real-life systems. We consider the optimization criterion which comprises two conflicting objectives, a minimization of processing time and a minimization of solvent consumption. The problem is treated in the multi-objective form in order to investigate the impact of operational cost factors on optimal operation policy. Thanks to the application of Pontryagin's minimum principle (PMP), we find the economically optimal operation of studied process in the analytical form. Developed methodology is applied to two case studies taken from literature.
间歇过滤过程的经济最优控制
对间歇过滤过程的经济优化操作进行了研究。该过程以复杂的膜传输模型为特征,该模型充分描述了现实系统的非理想膜特性。我们考虑的优化标准包括两个相互冲突的目标,处理时间的最小化和溶剂消耗的最小化。以多目标的形式来研究运行成本因素对最优运行策略的影响。通过对庞特里亚金最小原理(PMP)的应用,我们以解析形式找到了所研究过程的经济最优操作。开发的方法应用于两个案例研究,取自文献。
