| 摘 要： | 利用密度平移的方法对Peng-Robinson状态方程计算的液相密度进行了修正,给出了其描述平移量的关联式。对22种卤代烃纯物质的计算结果表明,修正后的PR方程能够很好地计算液相密度,并且能很好地再现纯物质的临界压缩因子,计算精度可以满足工程应用的需要。

| Abstract: | Density calculated by the PR EOS has been modified using the density translation method. Improved temperature dependent formula for the volume translation were developed, and an accurate representation of density near and far from the critical point for halogenated hydrocarbons was delivered. Comparisons between experimental data and the calculated values by the modified PR EOS and the original PR EOS show that the modified EOS can represent the experimental results accurately in a wide temperature range and the accuracy can meet the requirements of engineering applications. |
