2 Thermodynamic Modeling 2.1 Peng–Robinson The PR EoS in pressure-explicit form is [8]: P = RT − a v − b v(v + b) + b(v − b) (1) where parameters a and b are computed from van der Waals one-fluid mixing rules according to ∑∑ a = xixjaij ij (2) ∑...
Since its publication in 1976, the Peng & Robinson equation of state (PR EoS) has become one of the most useful and successfully applied models for thermodynamic and volumetric calculations in both industrial and academic fields. For this reason, we have reviewed this cubic EoS, in order to ...
The so-called "Peng-Robinson + residual Helmholtz energy -based mixing rules" equation of state is a promising thermodynamic model that enables the accurate representation of VLE properties of highly non ideal binary mixtures including the Type-Ill phase behaviour, according to the classification of ...
The Peng-Robinson equation of state (PR EoS) for liquid-vapor equilibrium is extended to model the solid-vapor (sublimation) and solid-liquid (melting) phase equilibria for carbon dioxide (CO2). The sublimation behavior is modeled through the re-formulations of the empirically based analytical ...
In this study, a thermodynamic model based on a modified Peng-Robinson equation of state is established to predict the dew point pressure. The presented model, using the MPR2 equation of state combined with a four-coefficient molar distribution function and the Kesler-Lee characterization method, ...
Additionally, it includes the comparison of model predictions when implementing two thermodynamic approaches: the Peng-Robinson Equation of State (EoS), and correlations developed in this work based on the Span-Wagner EoS. It was found that the thermodynamic approach is deeme...
