“…The liquid-phase activity coefficients for these five mixtures were estimated using the NRTL [19] and T-K-Wilson equations [21], with parameters adopted from the literature [7,8,27] ( Table 2). The parameters used for calculating the liquid molar volumes required for the T-K-Wilson equation…”

“…The reason of this deviation is attributed to the inability of the liquid-phase activity coefficient models to represent accurately the whole composition range and in particular the span of the two liquid phase region. It likely comes because the set of LLE data that was used to regress the activity coefficient model binary parameters lacks data in the decane-rich side [8,27].…”

Flash point is the most important variable used to characterize fire and explosion hazard of liquids. Herein, partially miscible mixtures are presented within the context of liquid-liquid extraction processes. This paper describes development of a model for predicting the flash point of binary partially miscible mixtures of flammable solvents.To confirm the predictive efficacy of the derived flash points, the model was verified by comparing the predicted values with the experimental data for the studied mixtures: methanol + octane; methanol + decane; acetone + decane; methanol + 2,2,4-trimethylpentane; and, ethanol + tetradecane. Our results reveal that immiscibility in the two liquid phases should not be ignored in the prediction of flash point. Overall, the predictive results of this proposed model describe the experimental data well. Based on this evidence, therefore, it appears reasonable to suggest potential application for our model in assessment of fire and explosion hazards, and development of inherently safer designs for chemical processes containing binary partially miscible mixtures of flammable solvents.

“…As an extension of our earlier works concerning (vapour + liquid) or (liquid + liquid) equilibria (VLE or LLE) [2][3][4][5][6][7][8], we present new phase equilibria data concerning chlorobenzene as an alternative extractive rectification solvent for the azeotropic mixture (benzene + cyclohexane) at a pressure of 101.3 kPa. No literature data have been made available for this system out of 9 experimental data points gathered in a recent paper [9].…”

In this paper, the azeotropic behaviour of the (benzene + cyclohexane + chlorobenzene) ternary mixture was experimentally investigated with the aim of enhancing the knowledge for the feasible use of chlorobenzene as an entrainer for the azeotropic distillation of the binary azeotrope. Such a study has not been reported in the literature to the best of the authors' knowledge. (Vapour + liquid) equilibria data for (benzene + cyclohexane + chlorobenzene) at 101.3 kPa were obtained with a Othmer-type ebulliometer. Data were tested and considered thermodynamically consistent. The experimental results showed that this ternary mixture is completely miscible and exhibits an unique binary homogeneous azeotrope, an unstable node at the conditions studied, and the propitious topological characteristics (residual curve map and relative volatility) to be separated. Satisfactory results were obtained for the correlation of equilibrium compositions with the UNIQUAC activity coefficients model and also for prediction with the UNIFAC method. In both cases, low root mean square deviations of the vapour mole fraction and temperature were calculated. The capability of chlorobenzene as a modified distillation agent at atmospheric condition is discussed in terms of the thermodynamic topological analysis. A conceptual distillation scheme with reversed volatility is proposed to separate the azeotropic mixture. In order to reduce the operational cost requirements of the sequence of columns proposed, the range for optimal reflux and the ratio for feed flow conditions were studied.
