利用Riazi-Daubert经验式修正和推导石油馏分迁移性质的计算式

Correction and Deduction of Petroleum Fraction lYansfer Formuh Using Riazi-Daubert Empirical Correlations

利用Riazi-Daubert经验关联式,对文献发表的原油和石油馏分动态表面张力计算式进行了修正,修正后的公式能应用于工程设计.开发了两种计算在低压下石油馏分导热系数的经验方法,所需参数少,准确性较高,计算简便,可用于不同种类石油馏分的计算.

The formula presented in literatures for calculating the dynamic surface tensions of crude oils and petroleum tractions were corrected using the Rizi-Daubert empirical correlations. The corrected formula is applicable in engineering design. Two methods for calculating thermal conductivities at low pressure for petroleum fractions were developed. Both methods are sim-ple, easy and suitable in calculation for various petroleum fractions with satisfactory accuracy.
