This function allows calculating the compressibility factor, the fugacity coefficient and density of a pure compound for both liquid and vapour phases by means of the Peng-Robinson equation of state (PR EOS). Temperature, pressure, molar weigth, and supercritical properties of the selected compound ...

In 2004, we started to develop a group contribution method aimed at estimating the temperature-dependent binary interaction parameters (kij(T)) for the widely used PengRobinson equation of state (EOS). This model was called PPR78 (predictive 1978, Peng Robinson EOS), because it relies on the...
