Leung-Griffiths equation of state for the system CO2-C2H4 near the liquid-vapor critical line

Abstract
The Leung-Griffiths equation of state has been used to represent the thermodynamic properties of the relatively simple system CO2-C2 H4 near the critical line. It has been shown that the model can account for the critical azeotropy exhibited by this mixture. The overall behavior is similar to that reported for He3-He4 mixtures.
