In the notebook flash.nb, we perform flash calculations of a mixture of hydrocarbons (ethane, propane, n-butane and n-pentane) using the Rachford-Rice equation. The phi-phi method, based on the SRK equation of state, is used to compute the equilibrium constants. We also find the True Vapor Pressure of the mixture. All results are in agreement with those given by HYSYS 3.2 as well as the results in the Master's thesis of Romain Privat from the Ecole Nationale Supérieure des Industries Chimiques de Nancy (Nancy, 2005) under the supervision of J-P Corriou.
In the notebook HS_SRK_Example4_10.nb, we obtain equilibrium constants, compressibility factors, molar volumes and densities using the Soave-Redlich-Kwong equation of state for a mixture of methane, ethane and propane. We find the same results as those given by Henley and Seader in Example 4-10 page 175 in Equilibrium-Stage Separation Operations in Chemical Engineering, Wiley, 1981.
