【摘要】 应用流程模拟软件Aspen Plus对环己酮-磷酸羟胺(HPO)法生产己内酰胺中的分离过程进行了模拟,在此基础上,建立了己内酰胺收率最大化、精馏塔能耗最小化和苯消耗量最小化的多目标优化模型。应用带精英策略的非支配遗传算法(NSGA-Ⅱ)对该模型进行了求解,所得最优解集Pareto前沿揭示了苯消耗量与能耗对己内酰胺收率影响的规律。本文工作对己内酰胺分离过程的设计与操作优化有参考作用。更多还原

【Abstract】 A process simulation software,Aspen Plus,is applied to create a separation process of caprolactam in the route of cyclohexanone-hydroxylamine phosphate in this paper,on the base of it,the multi-objective model of maximizing the yield of caprolactam,minimizing the consumption of distilled towers’ energy and minimizing the consumption of benzene is built.Non-dominated sorting genetic algorithm with elitist strategy(NSGA-Ⅱ) is employed to solve the model and then the Pareto front is obtained which reveals the law impact of the benzene consumption and the energy consumption on the yield of caprolactam.This work provides reference for caprolactam separation process in design and operation optimization.更多还原
