The supercritical fluid extraction of phenol, a common pollutant, from aqueous solutions is performed in a bench-scale extraction apparatus through the use of supercritical CO2 at 150 bar and 45 degreesC. The obtained results are satisfactory, and the influence of pressure and flow rate of supercritical CO2, as well as the co-solvent effect, are examined. Finally, the LCVM (Linear Combination of Vidal and Michelsen) mixing rules model, an EoS/G(E) (Equation of State/Gibbs free energy) one, thermodynamic model with new interaction parameters, combined with a simple mathematical one, is used successfully for the correlation of the experimental results by adjusting the overall volumetric mass transfer coefficients of the process.
