- Abstract:
-
In this study, isobaric vapor-liquid equilibria ( VLE) data for the ternary system of Ethyleneglycol, 1,4-Butylene glycol and Diethylene glycol were measured at 6. 67 kPa. The experimental data were correlated by the widely used NRTL, UNIQUAC, and Wilson models, and the results showed that the maximum average relative error between the experimental data and the predicted data was 5 . 3262%, which could meet the re-quirement of separation engineering.
