When applied to asymmetric binary mixtures (e.g., methane + pentane or heavier alkanes, hydrogen-containing mixtures), the GERG equation of state (GERG-2004 or GERG-2008) predicts critical curves with physically unreasonable temperature maxima above the critical temperature of the heavier component. These maxima are associated with physically impossible vapor–liquid equilibria. The phenomenon is probably caused by corrections for critical anomalies that were built into the empirical pure-fluid equations of state forming the foundation of the GERG model. These corrections ensure that the model represents thermodynamic data of pure fluids quite well even close to their critical points. For mixtures, however, the corrections can cause artifacts.

“…Significant effort has been made to investigate the thermodynamic properties of hydrogen-containing mixtures systematically [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] . In addition, the phase equilibria and solubility of Hydrogen-natural gas components contained blends have been studied by researchers (see Table 1).…”

the use of hydrogen (H 2) as a substitute for fossil fuel, which accounts for the majority of the world's energy, is environmentally the most benign option for the reduction of CO 2 emissions. this will require gigawatt-scale storage systems and as such, H 2 storage in porous rocks in the subsurface will be required. accurate estimation of the thermodynamic and transport properties of H 2 mixed with other gases found within the storage system is therefore essential for the efficient design for the processes involved in this system chain. In this study, we used the established and regarded GERG-2008 Equation of State (EoS) and SupertRaPP model to predict the thermo-physical properties of H 2 mixed with CH 4 , N 2 , CO 2 , and a typical natural gas from the North-Sea. the data covers a wide range of mole fraction of H 2 (10-90 Mole%), pressures (0.01-100 MPa), and temperatures (200-500 K) with high accuracy and precision. Moreover, to increase ease of access to the data, a user-friendly software (H2Themobank) is developed and made publicly available.
