Yu, Yingmin published the artcileEntrainers Selection and Vapor-Liquid Equilibrium Measurements for Separation of p-Xylene from Ethylbenzene at 101.3 kPa, Product Details of C2H5NO, the main research area is para xylene ethylbenzene trichlorobenzene vapor liquid equilibrium thermodn simulation.
In this paper, the separation of the p-xylene and ethylbenzene was explored. The COSMO-SAC-UNIFAC model, σ-profile anal., solvent power and selectivity were used to screen for a suitable solvent for this process. Then, 1,2,4-trichlorobenzene was selected as target solvent to extract the p-xylene from ethylbenzene. The vapor-liquid-phase equilibrium (VLE) data for binary systems of p-xylene + ethylbenzene, p-xylene + 1,2,4-trichlorobenzene, and ethylbenzene + 1,2,4-trichlorobenzene and ternary system of p-xylene + ethylbenzene + 1,2,4-trichlorobenzene were determined with a modified Rose still at atm. pressure (101.3 kPa) and all the binary data passed the Wisniak’s test, which accorded with the thermodn. consistency. Three thermodn. models, Wilson, NRTL and UNIQUAC were used to correlate the VLE data and get binary interaction parameters, then the ternary VLE data of p-xylene + ethylbenzene + 1,2,4-trichlorobenzene were estimated based on these model parameters using Aspen Plus V10. The estimation values of the three models are in good agreement with the exptl. data. Moreover, the effect of 1,2,4-trichlorobenzene was analyzed and it was found to be an effective candidate extractant for the extractive distillation of ethylbenzene from mixed xylenes.
