“…Patton et al (1993) have reported a special fluid phase behavior in the ternary mixture carbon dioxide + 1-decanol + n -tetradecane . They observed, in the three-phase surface liquid–liquid–vapor (l 1 l 2 g), a two-phase region liquid–vapor (lg) which is completely bounded by a closed loop critical end point locus of the type liquid = liquid + vapor (l 1 = l 2 + g).…”

In this paper, the modeling of holes in the critical surface and miscibility windows, in the ternary carbon dioxide + 1-hexanol + n-pentadecane and carbon dioxide + 1-heptanol + n-pentadecane systems, was made. A software for phase equilibrium (PHEQ) data management and applications was used for calculations with the cubic general equation of state (GEOS), developed by the author. The software PHEQ was extended for calculations of critical lines (module GEOS CRITHK), using the Heidemann and Khalil method, and liquid–liquid–vapor (llg) lines (module GEOS LLVE) in binary and ternary mixtures. These modules were used for the calculation of holes in critical surfaces, and of miscibility windows. Binary and quasi-binary measured phase equilibrium data by Scheidgen [Ph.D. Thesis, Ruhr-Universität Bochum, 1997] were necessary for understanding and modeling of ternary systems, regarding holes in critical surface and miscibility windows. For modeling, the equation of state Soave–Redlich–Kwong, integrated in the cubic GEOS form, coupled with the two-parameters conventional mixing rule was used. A simple semipredictive approach was adopted for the estimation of the two binary interaction parameters by a trial and error procedure for reproducing the temperature and pressure values of the two experimental double critical end points (DCEPs). A unique set of parameters obtained by this procedure was used to predict the critical and three phases llg lines for all quasi-binary systems at reduced mass fractions of n-pentadecane in the range between the two experimental DCEPs. The calculated holes in the critical surface and miscibility windows are in satisfactory agreement with the available experimental data.
