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.
► Experimental dew point data for six synthetic natural gas mixtures.
► Revision of the UMR-PRU model.
► The UMR-PRU model is applied in 23 synthetic natural and 2 real gas mixtures.
► The UMR-PRU model is compared with the PR and PPR78 EoS.
