Presentation

The research activity of EFIQ group is mainly focused on the thermodynamic study of mixtures of industrial interest, carrying out work on:

Determination of transport properties (mainly density and viscosity) of mixtures.
Experimental determination and modelling of phase equilibrium data.
Selection of solvents with reduced environmental impact, including ionic liquids and deep eutectic solvents, for use in non-conventional distillation processes (extractive and azeotropic) and liquid-liquid and solid-liquid extraction.
Distillations tests in pilot and semi-pilot plants.

The scientific and technical objectives of the EFIQ group are:

Obtaining experimental data of properties of liquid mixtures.
Obtaining and correlation of phase equilibrium data (liquid-vapour and liquid-liquid) of mixtures.
Determination of solubility and extraction kinetic under supercritical conditions.
Simulation of the behaviour of real systems.
Selection and technical evaluation of solvents with low environmental impact, substitutes for traditional solvents.
Recovery of extracts and reaction products dissolved in ionic liquids and deep eutectic solvents.
Extension of the database of properties and parameters of models.

The research lines of the EFIQ group are:

Transport properties. Experimental determination and theoretical estimation of thermodynamic and transport properties of mixtures containing electrolytes (salts and ionic liquids).
Phase equilibria. Experimental determination, theoretical estimation and data correlation of liquid-vapour and liquid-liquid equilibrium of systems of industrial interest. Determination of parameters of thermodynamic models. Obtaining of distillation curves maps in ternary systems.
Distillation processes. Simulation and analysis of non-conventional separation processes (extractive and azeotropic distillation). Experimental study on a pilot or laboratory scale of distillation processes. Rigorous determination of azeotropic points (pressure, temperature and composition).
Extraction processes. Study of the application of ionic liquids and deep eutectic solvents in the extraction of sugars from lignocellulosic residues. Extraction processes under supercritical conditions.
Recovery of solvents. Experimental study of the reuse of ionic liquids and eutectic solvents used in extraction proceses.
