A

We study the experimental determination of the viscosity, density and refractive index of organic mixtures and their variation with the composition, and the calculation of excess volumes of the components of organic mixtures.

Fields of application

(a) Chemical process equipment design.

(b) Functional analysis of chemical processes.

(c) Simulation of chemical processes.

 B

Study of the vapor-liquid equilibrium of binary and multicomponent mixtures in the following aspects:

a) Experimental determination of the equilibrium data for binary systems of industrial interest or which consist of compounds with functional groups that have not been studied sufficiently;
b) Estimation of the parameters of the most common thermodynamic models of vapor-liquid equilibrium (van Laar, Wilson, NRTL, UNIQUAC);
c) Experimental determination of equilibrium data of ternary and quaternary systems, and
d) Determination of activity coefficients at infinite dilution.

Fields of application
(a) Design and operation of equipment for distillation and rectification.
(b) Condenser design.
(c) Evaporator design.
(d) Liquid-liquid extraction equipment design.

This line aims to contribute to the experimental verification of the latest theories on classic and special distillation processes (extractive, azeotropic, etc.). To this end, we have a fully monitorised column with 30 trays, with possibility of taking samples and measuring the temperature in each tray and six possible feed entry points. This configuration allows for the analysis of residue curves and zones of distillation of multicomponent systems at both total reflux and normal working conditions.

Fields of application

(a) Study of special distillation.

(b) Search for the best solvents.

(c) Separation of azeotropic mixtures.
