摘要
石油化工用换热器传热计算大量涉及烃类及其混合物物性数据的计算。使用的参数,可供选择的计算公式广泛而且繁杂,如何正确地进行烃类及其混合物的密度计算,是传热计算中的基本问题。尤其在其它物性(如粘度、导热系数、炝、熵等)计算公式中,涉及到密度的情况下,能否正确确定密度值,就成为传热计算的关健。本文论述了烃类及其混合物密度计算的方法、程序,并对不同方法计算结果进行了比较。
The thermal conduction calculation of heat exchanger used in petrochemical engineering is largely related to physical data of hydrocarbon and its mixture. The parameters used and the calculation formulas selected are extensive and complex. How to correctly calculate the density of hydrocarbon and its mixture is the basic problem in the thermal conduction calculation. Especially in these calculation formulas used for calculating other physical data, such as viscosity, thermal conduction coefficient, enthalpy, entropy, etc., whether the density could be correctly determined is the key of thermal conduction calculation when it relates to density. This paper expounds the calculation method and program of the density of hydrocarbon and its mixture, and compares the results calculated with differient methods.
