用自制的冷镜装置对六种合成天然气（SNG）混合物进行了露点测量。实验数据涵盖的温度范围从253至285 K和压力范围从3至105巴。最近开发的UMR-PRU模型进行了修订，并适用于这些实验数据以及其他露点数据的合成和两个真实的天然气混合物在文献中报道。将UMR-PRU模型的结果与Peng-Robinson状态方程和经典货车-德尔-瓦尔单流体混合规则（使用零相互作用参数或温度依赖参数）得到的结果进行比较，这些参数用于PR EoS的预测版本，即所谓的PPR 78 EoS。(c)2012 Elsevier B. V.保留所有权利。
Dew point measurements for six synthetic natural gas (SNG) mixtures were performed using a custom made chilled mirror apparatus. The experimental data cover a temperature-range from 253 to 285 K and a pressure-range from 3 to 105 bar. The recently developed UMR-PRU model was revised and applied to these experimental data as well as to other dew point data for synthetic and two real natural gas mixtures reported in the literature. The results of the UMR-PRU model were compared to those obtained by the Peng-Robinson equation of state coupled with the classical van der Waals one fluid mixing rules using either zero interaction parameters or temperature dependent ones utilized in a predictive version of the PR EoS, the so-called PPR78 EoS.
