石油馏分苯胺点的新数学关联式

New Mathematic Correlation for Predicting the Anline Point of Petroleum Fractions

依据65份石油馏分的API°和中平均沸点数据,馏分选取范围广,包括石油的煤油,柴油和减压馏分油,拟合得出苯胺点的数学关联式,相关系数R为0.9914。通过计算结果与实际值对比,整体误差小,显示苯胺点计算公式准确度高,油品适用面大,实际来源数据容易得到,可以保证苯胺点计算需求,能够减轻实际测试苯胺点的人力和物资成本。苯胺点公式可以用在石油化工工艺计算和设计中。

According to the API° and medium average boiling point data of 65 petroleum fractions, the range of fractions is wide, including petroleum kerosene, diesel oil and vacuum distillate oil. The mathematical correlation of aniline points is obtained, and the correlation coefficient R is 0.9914. By comparing the calculated results with the actual values, the overall error is small, indicating that the aniline point calculation formula has high accuracy, the oil application surface is large, and the actual source data is easy to obtain, ensuring the calculation of the aniline point, and reducing the labor and material costs of the actual test aniline point. The aniline point formula can be used in petrochemical process calculations and design.
