新的石油馏分导热系数普遍化关联式

A NEW GENERALIZED CORRELATION EQUATION CALCULATING THERMAL CONDUCTIVITY OF PETROLEUM FRACTIONS

作者继开发石油馏分导热系数关联式后，利用国内外中平均沸点和相对密度分布范围很宽的各种石油馏分的大量实验数据，对关联式进行了考察。结果表明，关联式准确性高、使用简便、适用范围宽，能计算不同类型的石油馏分的导热系数，可用于工程设计。对其它一些导热系数的计算式也进行了考察，指出在使用《API技术数据手册》不同版本的导热系数计算式时应注意的问题。

A correlation equation developed by the author for calculating the thermal conductivity of petroleum fractions was investigated using the measured data of various petroleum fractions. The correlation equation is simple,easy in use and suitable for calculating thermal conductivity of various petroleum fractions with satisfactory accuracy in engineering design. Some other conventional calculation methods for thermal conductivity were also investigated.Matters needing attention in using the expression in the API Technical Data Book-Petroleum Refining for calculating thermal conductivity of petroleum fractions were also pointed out.
