Critical behavior and partial miscibility phenomena in binary mixtures of hydrocarbons by the statistical associating fluid theory
(AIP Publishing, 1998)Predictions of critical lines and partial miscibility of binary mixtures of hydrocarbons have been made by using a modified version of the statistical associating fluid theory (SAFT). The socalled softSAFT equation of ... 
Excess Thermodynamic Properties of Chainlike Mixtures. 1. Predictions from the Soft−SAFT Equation of State and Molecular Simulation
(American Institute of Physics, 2000)Monte Carlo simulation and theory are used to calculate excess thermodynamic properties of binary mixtures of LennardJones chains. Chainlike molecules are formed by LennardJones spherical sites that are tangentially bonded. ... 
Improved vapor–liquid equilibria predictions for LennardJones chains from the statistical associating fluid dimer theory: Comparison with Monte Carlo simulations
