原油性质及其与企业炼油装置的匹配性研究

原油组成及其性质非常复杂。要简明、准确地描述一种原油的性质是很困难的，而且已有评价和分类描述指标都不针对具体炼油装置。本文利用炼油PIMS模型针对具体炼油装置计算出了原油的性质匹配系数。利用这些匹配系数可以量化地比较各种原油的性质。企业实际加工原油的加权平均匹配系数一般应控制在0.60~0.80范围内。同时本文还指出，炼油装置综合配套能力强、产品质量标准低的企业，原油匹配系数相对较大，反之较小。

A STUDY OF THE ADAPTABILITY BETWEEN CRUDE OIL CHARACTERISTICS AND REFINING UNITS IN REFINERY

The composition and property of any crude oil are too complicated to have an accurate and precise characterization. The adaptability coefficient was defined as the ratio of the maximum potential capability processing a specific type of crude oil to the design distillation (both AD and VD) capability within any specific refinery. The coefficients of various types of crude oil in a specific refining unit were estimated by ASPEN PIMS model to quantitatively compare the variation of processing performance and crude oil property. It was concluded that the average adaptability coefficient of said refinery should be controlled in the range of 0.60~0.80 to maximize margin. It was found that the more comprehensive units the refinery has and the lower product quality standards required by the refinery, the higher the adaptability coefficient of crude oil and vice versa.
