Calculation and prediction of multicomponent azeotropes with activity coefficient modelsCálculo y predicción de azeótropos multicomponentes con modelos de coeficientes de actividad
(Centro de Informacion Tecnologica, 2008-05)
This paper studies the multicomponent azeotropic capacity prediction of activity coefficient models. Wilson and UNIFAC models are used for homogeneous azeotropes while UNIQUAC and UNIFAC models are used for heterogeneous ...
Phase Equilibria for Heterogeneous Azeotropic Distillation
(De gruyter, 2008-03)
Heterogeneous azeotropic distillation is used for separating no ideal mixtures. The technique uses minimum-boiling azeotropes and liquid-liquid immiscibilities in combination to break the azeotropes or tangent pinches in ...
Using Ionic Liquids To Break the Ethanol−Ethyl Acetate Azeotrope
(American Chemical Society, 2015-11-05)
Systems that form azeotropes or have relative volatilities close to 1.0 represent very little energy and capital intensive separations. Ionic liquids (ILs) can serve as nonvolatile entrainers to break azeotropes and enable ...
Azeotropic behaviour of (benzene + cyclohexane + chlorobenzene) ternary mixture using chlorobenzene as entrainer at 101.3 kPa
(The Journal of Chemical Thermodynamics, 2006)
Optimization of the operating conditions of azeotropic distillation columns with pervaporation membranes
(Planta Piloto de Ingeniería Química, 2003-06)
The main objective of this work is the optimization of the operating conditions of azeotropic distillation columns in hybrid distillation/pervaporation systems. In the configuration analyzed, a liquid side stream extracted ...
Development of a robust algorithm to compute reactive azeotropes

Effect of Vapor-Liquid Equilibrium Data on the Design of Separation Sequences by Distillation
(Planta Piloto de Ingeniería Química, 2009-12)
An evaluation of the effect of vapor-liquid equilibrium experimental data on the design of separation sequences by distillation was done using computer simulation. Separation of a mixture of ace-tone-chloroform-benzene was ...
Azeotropic behaviour of (benzene + cyclohexane + chlorobenzene) ternary mixture using chlorobenzene as entrainer at 101.3 kPa
(The Journal of Chemical Thermodynamics, 2006)
In this paper, the azeotropic behaviour of the (benzene + cyclohexane + chlorobenzene) ternary mixture was experimentally investigated with the aim of enhancing the knowledge for the feasible use of chlorobenzene as an ...
Prediction of azeotropic behavior using equations of state
(ELSEVIER SCIENCE BV, 1999)
A shortcut method is developed to determine if an equation of state (EOS) is capable of predicting azeotropes in binary systems and if the azeotrope meets the critical gas-liquid equilibrium line. The method suggested ...
Automated Generation of Phase Diagrams for Binary Systems with Azeotropic Behavior
(American Chemical Society, 2008-12)
In this work, we propose a computational strategy and methods for the automated calculation of complete loci of homogeneous azeotropy of binary mixtures and the related Pxy and Txy diagrams for models of the equation-of-state ...
