PSRK: A Group Contribution Equation of State Based on UNIFAC
T. Holderbaum,Jürgen Gmehling +1 more
TL;DR: A group contribution equation of state called PSRK (Predictive Soave-Redlich-Kwong) is proposed in this article to predict vapor-uquid-equilibria (VLB) for a large number of systems without introducing new model parameters.

Extension of the Peng-Robinson equation of state to complex mixtures: Evaluation of the various forms of the local composition concept
TL;DR: In this article, the authors investigate various aspects of the density-dependent local composition (DDLC) concept and offer two useful forms, one for the Peng-Robinson (1976) equation of state and the other for the non-ideal mixtures.

A modified Huron-Vidal mixing rule for cubic equations of state
TL;DR: In this paper, a new explicit mixing rule for a cubic equation of state has been developed, which enables direct incorporation of parameters from existing g E correlations, such as the Wilson equation, the NRTL equation or the UNIFAC equation.

Local compositions in thermodynamic excess functions for liquid mixtures
Henri Renon,John M. Prausnitz +1 more
TL;DR: In this paper, a new equation based on Scott's two-liquid model and on an assumption of nonrandomness similar to that used by Wilson is derived, which gives an excellent representation of many types of liquid mixtures.
