“…Any concentration unit (such as mole fraction or weight fraction) can be used for the calculation; however, consistent units should be used for both concentrations and for different components within a system. In the literature, concentrations in the liquid phase have been expressed either on a solvent-inclusive [10][11][12][13][14][15] or on a solvent-free basis [8,16,17]. When the liquid phase cannot be sampled and analyzed the solute concentration in the liquid phase is determined from mass balance calculations on a solvent-free basis as in the case of TG mixtures [8,16,17].…”

“…A literature review − would show that most of the high-pressure vapor−liquid equilibria calculations involving CO 2 and fish oil compounds are performed by means of a cubic equation of state (EOS). The most popular are the Redlich−Kwong−Soave and the Peng−Robinson EOS which require mixing rules when applied to mixtures.…”

In this paper, a purely predictive model for the phase equilibria computation of mixtures involving fatty acid esters (FAE) and supercritical carbon dioxide is proposed. In a first step, the phase equilibria modeling of FAE/CO2 binary systems were performed using the Peng−Robinson equation of state. To obtain a purely predictive model, the critical properties (T c, P c) and the acentric factor (ω) of the FAE were estimated with specific correlations. Moreover, the group contribution method developed by Abdoul et al., which allows the prediction of binary interaction parameters (k ij ), was extended to ester compounds and an additional group (the ester function) was defined. Such an approach allowed us to correlate with quite good accuracy all the binary FAE/CO2 systems. In a second step, dew points of (CO2/fish oil) systems were measured and the previous model was used to check its capability in predicting these data. The fish oil under study contained 30 different fatty acid ethyl esters, and the model was able to predict with very good accuracy the measured saturation pressures.

In this paper, a purely predictive model for the phase equilibria computation of mixtures involving fatty acids (FA) and supercritical carbon dioxide (SC-CO2) is proposed. In a first step, the phase equilibria modeling of FA/CO2 binary systems were performed using the Peng−Robinson equation of state. To obtain a purely predictive model, the group contribution method developed by Abdoul et al. which allows the prediction of the binary interaction parameters (k ij ) was extended to FA compounds. In a second step, the proposed model was used to predict the phase equilibria data of ternary and quaternary systems found in the literature. In a last step, bubble-point and dew-point pressures of systems involving CO2 and multicomponent mixtures of FA were measured in our laboratory, and the previous model was used in order to check its capability in predicting these data.
