Modeling phase equilibria in CO2 + polymer systems

• Review of thermodynamic models for phase behavior and swelling in CO2 + polymer systems.
• Advantages and disadvantages of cubic, lattice fluid, and SAFT models.
• New lattice fluid model with association.
• Discussion of future directions.

This work reviews thermodynamic models for the correlation and prediction of the phase behavior of CO2 + polymer systems. Advantages and shortcomings of cubic equation of state, the SAFT equation, and Lattice fluid models are discussed. Perspectives and future directions in the development of thermodynamic models for CO2 + polymer systems are presented.
