摘要
石油馏分的4种平均沸点在石化行业的工艺技术中是一个经常使用的特性参数。这里介绍了一个矩阵计算公式,可以由恩氏蒸馏数据很方便地求得质量、立方、分子、中平均沸点。在49～487℃馏分范围内,平均相对误差为0.07～0.10％,最大相对误差为1.7％。这种计算方法也可类推至其它多簇曲线的拟合。
Various average boiling points of petroleum fractions are frequently used in petrolchemical process calculations. A matrix equation have been developed with which the four average boiling points (weight,cubic,molal and mean) of petroleum fractions can be obtained form ASTM D-86 data. It is easy to use. The average relative deviation is 0.07～0.10%,and the maximum relative deviation is 1.7% for fractions ranging in 49～487℃. This method can be used in fitting of other curves com- posed with multi-group curves.
