I am looking for binary interaction parameters for Peng Robinson equation. I would prefer if the binary interaction parameters are predictive and simple to calculate and include inorganic gases like N2, CO2, H2S, He, H2, Ar, O2 and CO besides all types of non polar hydrocarbons.
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. The most prominent use of an equation of state is to correlate densities of gases and liquids to temperatures and pressures. One of the simplest equations of state for this purpose is the ideal gas law, which is roughly accurate for weakly polar gases at low pressures and moderate temperatures. The ability of the Peng−Robinson equation of state (PR EOS) to calculate the high-pressure, multiphase behavior of select binary systems has been examined using K- and L-points (also referred to as critical end points) in phase space as key landmarks and adjusting the attractive term binary interaction parameter (δ12). parameters of the Peng–Robinson (PR) and those of the Soave–Redlich–Kwong (SRK) equations of state (EoS). This equivalence makes it possible to find out a relationship between the Eij(T) parameters issued from the Van Laar function and the kij(T) of the classical mixing rules
