![عکس صفحه اول مقاله: Measurements and thermodynamic modeling of the ethanol–water system with emphasis to the azeotropic region Measurements and thermodynamic modeling of the ethanol–water system with emphasis to the azeotropic region](/preview/png/204425.png)
Recovery of bioethanol from the fermentation broth is classically achieved by distillation. The design and optimization of the distillation requires a reliable thermodynamic model that describes sufficiently the properties of the ethanol/water mixture, and, especially, the vapor–liquid equilibrium (VLE) near the azeotropic point. The purpose of this study is twofold: first, to provide new reliable low-pressure VLE data for the ethanol/water mixture with emphasis given near the azeotropic region, and second, to develop new temperature-dependent binary interaction parameters for three excess Gibbs energy models (UNIQUAC, Wilson and NRTL), by fitting simultaneously VLE data, azeotropic points and excess enthalpies for this mixture.
► New thermodynamically consistent low-pressure VLE data for the ethanol/water mixture with emphasis near the azeotropic region.
► New temperature-dependent binary interaction parameters for the UNIQUAC, Wilson and NRTL models.
► Simultaneous fitting of VLE data, azeotropic points and excess enthalpies.
