Abstract

Five equations of state (including one recently proposed by the authors) have been applied to the calculation of vapour-liquid equilibrium (VLE) of CO₂-n-alkane mixtures. Interaction parameters for several systems have been obtained through regression analysis of experimental VLE data. These parameters have been correlated in terms of the temperature and the acentric factor of the hydrocarbon for three equations of state and for all systems. It is concluded that while all equations perform more or less with the same degree of accuracy, there are some advantages in using one or another for different VLE calculations.
