基于AsPen Plus的常压蒸馏装置流程优化

为增加年综合收益，应用流程模拟软件Aspen Plus对某厂一套常压蒸馏装置进行流程优化。在流程模拟的基础上，给定约束条件，优化决策变量，建立了以年综合收益最大为目标函数的优化模型，并在Aspen Plus平台上进行二次开发，对优化模型进行了求解，获得了良好的优化结果，详细分析了产品收益与泵动力消耗、加热和冷却负荷以及蒸汽消耗等成本对年综合收益的贡献率及影响。最终得到了年综合收益最大化下的各工艺参数。

Flow Optimization of an atmospheric distillation unit based on aspen plus

Flow optimization of an atmospheric distillation unit based on a flow simulation software, Aspen Plus, was completed to increase the annual profit. Based on the flow simulation, the article given constraint condi-tions, optimization decision variables, then optimization model is established. The optimization model is solved on Aspen Plus platform. Good optimization result is achieved. The profit's contribution of products and cost of pump work, heat or cool duty, and steam consumption to annual profit of the atmospheric distillation unit and the influence of these factors on the annual profit were analyzed in detail. At last we get the processing parame-ters under the maximum annual profit.
