摘　　要：采用基于PR方程的PENG-ROB的物性方法,运用过程模拟软件Aspen Plus,以年度总费用最低的原则对石油裂解C_5以下液态烃的前脱丙烷工段进行模拟与优化。在建立前脱丙烷工段流程的同时,利用过程模拟软件Aspen plus中的灵敏度分析功能确立了理论塔板数、进料塔板等参数对分离效果和经济效益的影响,从而确定了最优工艺参数。该参数为此工艺提供了降低能耗和较少投资费用的依据。The PENG-ROB physical property method based on PR equation is used to simulate and optimize the prodepropanization section of petroleum hydrocarbons below C_5 in the principle of the lowest annual total cost by using process simulation software Aspen plus. In the process of establishing the pre-depropanizer section,the influence of the number of theoretical plates,feed tray and other parameters on the separation efficiency and economic benefits was established by using the sensitivity analysis function of the process simulation software Aspen plus to determine the optimum process parameters. This parameter provided the basis for this process to reduce energy consumption and less investment costs.
