本文对某原油蒸馏装置进行了优化设计。由于这里使用的方法是基于一般的优化框架，因此可以系统地设计过程。本研究的结果给出了更好的性能比现有的过程。本研究中的工艺目前正在运行，产能为150，000 BPSD。以进料位置、循环热负荷和预热机组运行工况为变量，以能耗、运行费用和年费用为目标函数。通过求解严格模型和混合整数非线性规划，得到了主塔和稳定塔的最佳进料位置。考虑到最佳进料盘的结果，成本优化被结转，以获得最佳的年成本，该年成本考虑了资本和操作成本，从10，649，000美元/年降低到9，185，230美元/年。
In this work, the optimal design of a crude oil distillation unit was made. Since the method used here is based on the general optimization framework, it is possible to design the process systematically. The results of this study gave better performances than that of the existing process. The process in this study is currently in operation and has the capacity of 150,000 BPSD. Feed locations, heat duties of pumparounds and operating conditions of the preheat train are selected as variables, and the energy consumption, operating cost and annual cost are formulated as objective functions. The optimal feed locations of both the main column and stabilizer are obtained by solving rigorous models and mixed integer nonlinear programming. Considering the results of the optimal feed tray, the cost optimization is carried over to obtain the optimal annual cost, which considers both the capital and operating cost, which is decreased from US$10,649,000/year to USdollar;9,185,230/year.
