Representation of oxygenated fluids associated with biomass valorization: descriptor definition
Tanh Binh NGUYEN thesis defense, november 26, 2013 "Représentation des charges oxygénées associées à la valorisation de la biomasse: définition de descripteurs"
Publications :
- "GC-PPC-SAFT Equation of State for VLE and LLE of Hydrocarbons and Oxygenated Compounds. Sensitivity Analysis", 2013, Ind. Eng. Chem. Res, Vol 52, p7014-7029
- In 2014, the work related to mutual solubilities of water and various oxygenated compounds was published:
One of the most remarkable result of this work is the quality of the predictive representation of octanol-water partition coefficients, as shown below:

In this last work, it is proposed to use five well-defined and measurable properties in order to determine a molecular surrogate molecule that can be used for thermodynamic computations. The five properties are density, molecular weight, viscosity, refractive index and dielectric constant. The reconstruction procedure is summarized in this sketch.

The quality of the model for representing both vapour liquid and liquid-liquid equilibria is illustrated in the figure below:
VLE for ammonia + n-butane at (♢) 273.15 K and (□) 323.15 K. Symbols represent experimental data, solid lines are GC-PPC-SAFT VLE predictions, dotted lines are GC-PPC-SAFT LLE predictions. All kij = 0.
