Determination and Prediction of the Isobaric Vapor-liquid-liquid Equilibrium Data
نویسنده
چکیده
The prediction method of the isobaric vapor-liquid-liquid equilibria (VLLE) data for the system ethanol-water-1-butanol and ethanol-2-butanol-water was studied. The parameters for the activity coefficients models were determined from the constituent binary VLE data. With the parameters, the isobaric ternary VLLE data were predicted and compared with the experimental ones obtained in our previous study. Furthermore, a prediction method based on successive calculations of LLE at boiling point and VLE was studied. For this method, the two sets of the parameters were independently determined for LLE and VLE calculation. The VLLE data predicted by this method were in good agreement with the experimental ones.

In this work, a more accurate prediction of liquid evaporation flux has been achieved. The statistical rate theory approach, which is recently introduced by Ward and Fang and exact estimation of vapor pressure in the layer adjacent to the liquid–vapor interface have been used for prediction of this flux. Firstly, the existence of an equilibrium layer adjacent to the liquid-vapor interface ...
