“…Another pressure-explicit EOS established by Demetriades and Graham should be acknowledged for CCS pipeline transport . The industrially recognized cubic EOS, such as Soave–Redlich–Kwong (SRK) and Peng–Robinson (PR), have been extensively used for these systems, completing experimental measurements to calculate phase equilibria and critical properties of binary mixtures with H 2 , − as well as derivative and transport properties. − Despite the success of cubic equations for describing H 2 -related fluid mixtures, the theory depends on the additional parameters regressed to extensive collections of experimental data, in which the extrapolation under other thermodynamic conditions remains unidentified. In addition, the accuracy of these equations decreases when predicting the behavior of substances that form strong associations between molecules, as classical EOS were developed by considering only dispersion forces.…”

The catalytic hydrogenation of carbon dioxide has become a novel technology of economic and environmental interest that allows the production of value-added products as energy alternatives to the current demand. As product distributions are highly dependent on process conditions such as reaction temperature, pressure, and H 2 /CO 2 ratio, it is necessary to have reliable thermodynamic models that can characterize mixtures of reactants with products over a wide range of conditions. In this contribution, the accuracy of two hydrogen models applied through equations of state (EOS) framed within variations of the statistical associating fluid theory (SAFT) is compared. These models include perturbed-chain SAFT (PC-SAFT) EOS and SAFT of variable range and Mie potential (SAFT-VR Mie) EOS. This is accomplished by the depiction of the thermodynamic behavior of mixtures of hydrogen in the context of the hydrogenation of carbon dioxide, estimating the thermodynamic behavior of the relevant mixtures. In all of the cases, zero values for the binary adjustable parameters have been implemented, and both models of hydrogen were fitted from a hydrogen+decane mixture. Available experimental data of high-pressure phase equilibria, critical loci, and interfacial tensions is used to determine the accuracy of the hydrogen models by contrasting their respective predictive capabilities, determining that the overall performance of the one applied in the SAFT-VR Mie EOS is inferior compared to the PC-SAFT one. The average absolute deviations between model calculations and experimental data for vapor−liquid equilibrium are 35.8 % (pressure), 3.10 % (liquid composition), and 2.60 % (vapor composition) for PC-SAFT, and 26.3, 3.27, and 2.65% for SAFT-VR Mie, respectively.

“…The industrially recognized thermodynamic models for natural gas systems include classical cubic equations of state (EoSs) such as Peng–Robinson (PR) and Soave–Redlich–Kwong (SRK) as well as multiparameter empirical EoSs such as Groupe Européen de Recherches Gazières (GERG)-2004/2008 , and AGA8-DC92, primarily for their good predictive accuracy and accessibility in common engineering simulators and thermodynamic databanks. In the context of H 2 -rich systems of interest for NG pipeline transportation, the use of classical cubic EoSs has mainly focused on modeling the phase equilibria and critical loci of binary mixtures with H 2 − and to a lesser extent examining other properties such as the Joule-Thomson (JT) coefficient , and viscosity . Although these models are easy and simple to use, a good level of VLE modeling accuracy would require additional parameters regressed to extensive collections of experimental data that are otherwise unsuitable for extrapolation beyond the fitting range.…”

This work demonstrates the need for accurate thermodynamic models to reliably quantify changes in the thermophysical properties of natural gas when blended with hydrogen. For this purpose, a systematic evaluation was carried out on the predictive accuracy of three well-known models, the Peng−Robinson equation of state (EoS), the multiparameter empirical GERG-2008 model, and the molecular-based polar soft-SAFT EoS, in describing the thermodynamic behavior of mixtures of hydrogen with commonly found components in natural gas. Deviations between the calculated properties and experimental data for phase equilibria, critical loci, second-order derivative properties and viscosities are used to determine the accuracy of the models, with polar soft-SAFT performing either equally or better than the other two examined models. The evaluation for the effect of H 2 content on the properties of methane, simulated as natural gas at conditions for transportation, reveals higher changes in blend density and speed of sound with increasing H 2 content within 5% change per 5 mol % H 2 added, while viscosity is the least affected property, changing by 0.4% for every 5 mol % H 2 .

The Joule–Thomson effect is a key chemical thermodynamic property that is encountered in several industrial applications for CO 2 capture and storage (CCS). An apparatus was designed and built for determining the Joule–Thomson effect. The accuracy of the device was verified by comparing the experimental data with the literature on nitrogen and carbon dioxide. New Joule–Thomson coefficient (μ JT ) measurements for three binary mixtures of (CO 2 + N 2 ) with molar compositions x N 2 = (0.05, 0.10, 0.50) were performed in the temperature range between 298.15 and 423.15 K and at pressures up to 14 MPa. Three equations of state (GERG-2008 equation, AGA8-92DC, and the Peng–Robinson) were used to calculate the μ JT compared with the corresponding experimental data. All of the equations studied here except PR have shown good prediction of μ JT for (CO 2 + N 2 ) mixtures. The relative deviations with respect to experimental data for all (CO 2 + N 2 ) mixtures from the GERG-2008 were within the ±2.5% band, and the AGA8-DC92 EoSs were within ±3%. The Joule–Thomson inversion curve (JTIC) has also been modeled by the aforementioned EoSs, and a comparison was made between the calculated JTICs and the available literature data. The GERG-2008 and AGA8-92DC EoSs show good agreement in predicting the JTIC for pure CO 2 and N 2 . The PR equation only matches well with the JTIC for pure N 2 , while it gives a poor prediction for pure CO 2 . For the (CO 2 + N 2 ) mixtures, the three equations all give similar results throughout the full span of JTICs. The temperature and pressure of the transportation and compression conditions in CCS are far lower than the corresponding predicted P inv,max and T inv,max for (CO 2 + N 2 ) mixtures.
