严格的优化是一个有价值的工具，可以支持工程师挖掘蒸馏过程的全部经济潜力。不幸的是，这些大规模的离散-连续优化问题的解决方案通常遭受缺乏鲁棒性，计算时间长，以及对良好的局部最优值的可靠性低。在本文中，严格的优化复杂精馏过程的共沸多组分混合物实现突出的鲁棒性，可靠性和效率，通过两个层次上的进展。首先，在一个过程综合框架内的集成允许减少优化超结构的复杂性，并提供了一个很好的初始化与整流体方法的快捷评价。其次，将其重新表述为一个纯粹的连续优化问题，可以使用可靠和高效的NLP求解器来解决问题。此外，连续重新考虑一个特定的紧柱模型制定，使…
Rigorous optimization is a valuable tool that can support the engineer to tap the full economic potential of a distillation process. Unfortunately, the solution of these large-scale discrete-continuous optimization problems usually suffers from a lack of robustness, long computational times, and a low reliability toward good local optima. In this paper, the rigorous optimization of complex distillation processes for azeotropic multicomponent mixtures is achieved with outstanding robustness, reliability, and efficiency through progress on two levels. First, the integration within a process synthesis framework allows a reduction of the complexity of the optimization superstructure and provides an excellent initialization by shortcut evaluation with the rectification body method. Second, the reformulation as a purely continuous optimization problem enables a solution with reliable and efficient NLP solvers. Moreover, the continuous reformulation considers a particular tight column model formulation such that...
