“…. .and were successfully applied to describe high pressure fluid phase equilibria of mixtures containing polar compounds ( [32,33] as examples). A complete review of EoS/G E mixing rules and their range of application can be found in the recent book of Kontogeorgis and Folas [34].…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. This is an author-deposited version published in : http://oatao. a b s t r a c tPhase equilibrium experimental data for the CO 2 /glycerol system are reported in this paper. The measurements were performed using an in situ FT-IR method for temperatures ranging from 40 • C to 200 • C and pressures up to 35.0 MPa, allowing determination of the mutual solubility of both compounds. Concerning the CO 2 rich phase, it was observed that the glycerol solubility in CO 2 was extremely low (in the range of 10 −5 in mole fraction) in the pressure and temperature domains investigated here. Conversely, the glycerol rich phase dissolved CO 2 at mole fractions up to 0.13. Negligible swelling of the glycerol rich phase has been observed. Modeling of the phase equilibrium has been performed using the Peng-Robinson equation of state (PR EoS) with classical van der Waals one fluid and EoS/G E based mixing rules (PSRK and MHV2). Satisfactory agreement was observed between modeling results and experimental measurements when PSRK mixing rules are used in combination with UNIQUAC model, although UNIFAC predictive approach gives unsatisfactory representation of experimental behavior.

“…Regarding the system (methanol + H 2 O) (figure 6), the level of deviation between the predicted SRK-MHV2 p-x-y curves [20] and those predicted by the PRSV and PT EoS is significantly higher. Concerning the (DMC + methanol) system (figure 7), some inaccuracy is observed, since the proposed models underestimate the concentration of DMC in vapour phase, and this effect sharply increases with temperature.…”

“…Binary subsystems A review of experimental p-x-y phase equilibria data (table 2) has been made by selecting results from the binary systems: (CO 2 + methanol) [17], (CO 2 + H 2 O) [18], (CO 2 + DMC) [19], (methanol + H 2 O) [20] and (DMC + methanol) [20,21]. Regarding the system (methanol + H 2 O), the VLE was calculated using the SRK EoS with the MHV2 mixing rule, whose adjusted parameters were calculated by Camy et al [20].…”

“…Going further, the basic aim of this model is to improve the predictive ability of the PRSV EoS by seeking a linear temperature dependency of the binary interaction parameters (k ij , l ij ) which allow extrapolating at higher temperatures and predicting the phase behaviour at different operating conditions. The temperature dependency of the binary interaction parameters, in addition to usage of the Van der Waals mixing rule which can be easily integrated into complex simulation routines, represents a remarkable advantage against the complexity of other mixing rules based on G EX , as reported in the literature [20].…”
