RODRIGUES, M. A. et al. Efficiency of water removal from water/ethanol mixtures using supercritical carbon dioxide. Braz. J. Chem. Eng. [online]. 2006, vol.23, n.2, pp.205-212. ISSN 0104-6632.

Techniques involving supercritical carbon dioxide have been successfully used for the formation of drug particles with controlled size distributions. However, these processes show some limitations, particularly in processing aqueous solutions. A diagram walking algorithm based on available experimental data was developed to evaluate the effect of ethanol on the efficiency of water removal processes under different process conditions. Ethanol feeding was the key parameter resulting in a tenfold increase in the efficiency of water extraction.

Keywords : Water [ethanol mixtures]; Supercritical carbon dioxide.
