摘　　要：精馏是高耗能的操作单元,对其进行操作优化是企业实现节能降耗、提高经济效益的有效手段。本文提出列队竞争算法与流程模拟软件相结合的精馏操作优化方法,通过MATLAB-Aspen Plus的接口工具调用AspenPlus模拟精馏操作过程,得到目标函数值,使用列队竞争算法对其进行操作条件的优化。将所提出的方法应用于某石化企业催化裂化主分馏塔的操作优化,其中目标函数值同时考虑了热能利用与产品分布,优化求解得到了总体效益最大的优化操作方案。In this paper,an optimization method based on the line-up competition algorithm（LCA） coupled with a sequential process simulator was proposed for optimizing distillation operation process.The distillation operation process was simulated by Aspen Plus and optimized by LCA through the interface of Matlab and Aspen Plus.The proposed method has been applied to the main fractionator of fluid catalytic cracking（FCC） in a major refinery plant.The heat energy use and product distribution were both considered in the objective function.The best overall benefit scheme was obtained after the optimization process.
