在原油切割中使用常减压装置模拟，一方面为第三方软件提供符合实际常减压装置的原油及馏分物性数据，更好的为计划优化模型、调度优化模型以及全流程优化模型提供数据；另一方面可分析市场上的新油是否适合该厂常减压装置的蒸馏情况，更好的指导工艺生产。本文针对现有原油切割中常减压装置模拟的不足，采用半严格的简捷精馏计算方法，从相对挥发度、分馏指数、参考组分等方面对常减压装置模拟进行研究分析。在半严格的简捷精馏计算方法中，使用芬斯克方程获得能表征常减压装置分离效率的参数即有效切割温度(ECP)、提馏指数(stripping FI)和精馏指数(rectifying FI)。使用CrudeManager软件和某厂的常减压塔数据进行模拟分析，获得常减压装置各馏分的有效切割温度14.1℃、186.8℃、258.6℃、341.4℃、452.9℃、536.0℃，提馏指数，精馏指数和蒸馏曲线，结果显示该方法能准确地模拟常减压装置，很好地解决了馏分间的返混问题，具有良好的应用价值。

Simulation of Atmospheric and Vacuum Distillation Unit is used in crude oil recutting. On the one hand, to provide crude oil and product’s properties of practical Atmospheric and Vacuum Distillation Unit for the third party software, and for planning optimization model, scheduling optimization model and process optimization model;On the other hand, to analyze the new oil on the market, to judge whether the oil is suitable for the distillation of Atmospheric and Vacuum Distillation Unit for the plant, and to guide the production process better. In this paper, against to simulation of Atmospheric and Vacuum Distillation Unit’s shortage, using a semi-rigorous short-cut distillation method, it is researched and analyzed on simulation of Atmospheric and Vacuum Distillation Unit. It is researched from relative volatility, fractionation indices, reference component, etc. In the semi-rigorous short-cut distillation method, using the Fenske Equation, it is obtained parameters of the true efficiency of the separation of Atmospheric and Vacuum Distillation Unit, as effective cut point(ECP), stripping fractionation index (stripping FI) and rectifying fractionation index (rectifying FI). Using CrudeManager software and the actual data of Atmospheric and Vacuum Distillation Unit in a refinery to simulate and analyze, it is obtained ECP of the cuts as 14.1 ℃, 186.8 ℃, 258.6 ℃, 341.4 ℃, 452.9 ℃, 536.0 ℃, stripping FI, rectifying FI and distillation graphs. The results showed that the method can accurately simulate Atmospheric and Vacuum Distillation Unit and model imperfect fractional distillation of crude oils, had a good application value.
