Prediction of Vapor-Liquid Equilibria Using CEOS /GE Models
The present study investigates the use of different GE mixing rules in cubic equations of state for prediction of phase behavior of multicomponent hydrocarbon systems. To predict VLE data in multicomponent symmetric and asymmetric mixtures such as systems that contain light gases (nitrogen, carbon dioxide, etc.) and heavy hydrocarbons, the SRK equation of state has been combined with excess Gib...
متن کاملA new modified Wilson equation for the calculation of vapor–liquid equilibrium of aqueous polymer solutions
A local composition model based on the lattice theory and two-fluid theory, considering the excess heat capacity, which is a modified Wilson equation, is developed for the excess Gibbs energy of aqueous polymer solutions. The model represents a synergistic combination of the excess entropy for mixing molecules of different sizes and the temperature dependent residual contribution, which combine...
متن کاملNew Local Composition-Equation of State Mixing Rules for High Pressure Vapor-Liquid Equilibria Using EOS/AE
In this study using Equation of State/ Helmholtz excess energy function, EOS/AE, two new local composition-Equation-of State mixing rules, LCEOS1 and LCEOS2 were developed in which the energy interaction parameters were expressed in terms of attractive and repulsive parameters of the cubic equation of state. The EOS/AE models are applied for equilibrium calculation of nat...

متن کاملMolecular Simulation of Three-body Interactions for Vapor-liquid and Solid-liquid Phase Equilibria
The phase behavior of both pure systems and binary mixtures has been widely studied by molecular simulation [1], using techniques such as the Gibbs ensemble [2], Gibbs-Duhem [3] or histogram reweighing [4] algorithms. The common aim of many of these investigations is to accurately predict the phase diagram using effective intermolecular potentials, most notable the Lennard-Jones potential. In c...
