Modeling Of Thermodynamic Properties Of H 2 And H 2 Mixtures Using A Three-Parameter Cubic Equation Of State

Résumé

Throughout the hydrogen value chain, industries increasingly rely on digital tools utilizing equations of state to develop safer, more efficient, and cost-effective processes. This paper compares the Peng-Robinson equation of state with volume translation (tc-PR EoS) and the Coquelet-El Abbadi-Houriez equation of state (CAH EoS), modified with the Feymann Hibbs correction to the covolume, to account for the quantum swelling phenomenon. The models were used to predict density, residual enthalpy, and Joule-Thomson coefficients over a temperature range of 20 to 353 K. It has been applied to binary mixtures relevant to the hydrogen industry, including H2/CO2, H2/CO, H2/CH4, and H2/N2. Model parameters were fitted to liquid-vapor equilibrium (VLE) data using the generalized Wong-Sandler (gWS) and van der Waals (vdW) classical mixing rules. The performance of the models in representing VLE data and densities over a wide range of thermodynamic conditions was assessed. These models can help design processes for hydrogen production, transport and use.
