Abstract: 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.
