Each column in every sequence is optimized separately, and the total cost of each sequence is calculated. This method benefits from both the rigor of column modeling in a process simulator and the flexibility of implementing sequential procedures and derivative-free optimization in a procedural programming language. Using this method, a single column can be optimized within 6 min of computer time. Furthermore, when stacking rules and available utilities are specified, a nearly optimal heat-integrated distillation column sequence can be designed automatically. Results are illustrated using two case studies of column sequencing problems. Copyright ? 2018 American Chemical Society. |
