This repository contains the python codes necessary to model the thermophysical properties (i.e., phase equilibria, interfacial properties, viscosity) of biphasic systems measured at the Cohesion Laboratory (Concepción University). At the time the systems included in this repository are:
-
Dibutyl Ether + Butan-1-ol binary mixture: Containing vapor-liquid equilibria (VLE) and viscosity experimental data, thermodynamic consistency test of VLE, and their modeling using the SAFT-VR Mie EoS coupled with Helmholtz Scaling theory.
-
Hexane + CPME + Propanol: Containing vapor-liquid equilibria (VLE), liquid mass densities, liquid viscosities and surface tensions experimental data and their modeling using the SAFT-VR Mie EoS coupled with Helmholtz Scaling theory and with the Square Gradient Theory.
-
2-Methylfuran + Ethanol: Containing the point-point consistency test based on the 𝛾−𝜙 proposed by Fredenslund et al., approach, calculation of the experimental activity coefficients and excess Gibbs energy, and the parametrization of the following activity coefficients: Porter, 2-suffix Margules, NRTL, Wilson, and UNIQUAC.
-
Diethyl Carbonate + 1-Butanol Binary Mixture: Containing vapor-liquid equilibria (VLE), viscosity, and surface tension, experimental data, thermodynamic consistency test of VLE based on the point-point consistency test proposed by Fredenslund et al., approach, calculation of the experimental activity coefficients and excess Gibbs energy, and the parametrization of the following activity coefficients:2-suffix Margules, NRTL, Wilson, and UNIQUAC. The VLE predictions are based on the Peng-Robinson EoS with Modified Huron-Vidal mixing rule. The viscosity predictions are based on the Helmholtz Scaling theory, and surface tensions are calculated with the Cunxi model.
