Statistical associating fluid theory: A successful model for the calculation of thermodynamic and phase equilibrium properties of complex fluid mixtures Academic Article uri icon


  • Statistical associating fluid theory (SAFT) is a powerful model for thermodynamic property and phase equilibrium calculations for fluid mixtures. In this paper, the model development, modifications, and generalizations proposed over the past decade are reviewed. Emphasis is given to developments resulting in equations of state applicable to real fluids. In addition, theoretical models are reviewed. Applications are discussed, and representative calculations are presented with emphasis on aqueous systems and polymers. Despite its wide acceptance, SAFT has several limitations that are discussed here.
