摘要
应用流程模拟技术对加氢裂化分馏塔进行了模拟,在此基础上,建立了以航煤量、柴油量、尾油量、加热炉温、塔底蒸汽量、柴油侧线蒸汽量、中段回流量为优化操作变量,以产品总值和能耗为优化目标的加氢裂化分馏塔优化模型。应用改进强度Pareto进化算法(SPEA2)求解多目标模型得到Pareto前沿。基于Pareto前沿各产品量的分布,确定了多产航煤、多产柴油与多产尾油3种方案的优化操作点,并给出了3种产品方案优化操作点的雷达图,此雷达图为产品方案的调整提供了一种可视化手段。本文方法对加氢裂化分馏塔多产品方案的操作优化具有参考作用。
The process simulation software of Aspen Plus is used to simulate hydrocracking fractionator. Then a multi-objective optimization model is established which has seven operating variables, kerosene flow rate, diesel flow rate, bottom oil flow rate, heating furnace temperature bottom steam flow rate, stripping steam flow rate, reflux flow rate, and two targets, gross products value and energy consumption. Strength Pareto Evolutionary Algorithm 2 （SPEA2） is used to search the pareto front. Based on products distribution, optimal operating point as well as its radar chart is given in three product schemes. The radar chart provides a visualization tool for schemes adjustment. Method in this paper is of referential significance for operation optimization of hydrocracking fractionator.
