| 摘 要： | 对17个含氮二元体系的高压汽液平衡数据，按4个状态方程（SPK、PR、PT和YL）关联了二元交互作用参数值，并对PT方程建立了关联式。基于二元体系的关联结果，对19个三元至十元含氮体系的泡点压力和液相密度进行了预测计算，结果表明PT方程的预测效果最佳。

| Abstract: | Binary interaction parameters ( k ij ) have been determined for 17 N 2 hydrocarbon mixtures by using four equations of state, SRK, PR, YL and PT The k ij values for PT equation of state have been correlated The phase behavior of N 2 containing multicomponent systems have been predicted based on the four equations of state The calculated results indicate that PT equation of state is the best one for predicting liquid phase densities and bubble point pressures |
