| Abstract: | New and reliable empirical correlations for predicting the average boiling points of petroleum fractions,which include mass average boiling point, molar average boiling point, cubic average boiling point and mid-average boiling point,were proposed and the deviation was analyzed. It was showed that the results calculated by the new mathematic correlations coincided well with those obtained from the boiling point curve of petroleum fractions.The new mathematic correlations are especially applicable to on-line caluation optimization. |
