Isobaric Vapor-Liquid Equilibrium of Benzene-Thiophene-Dimethyl Sulfoxide Systems
摘要
Abstract
Isobaric vapor-liquid equilibrium (VLE) data of the benzene-thiophene-dimethyl sulfoxide (DMSO) ternary system and two constituent binary systems of benzene-thiophene and benzene-DMSO were measured at 101.33 kPa.The experimental apparatus was an all-glass double recirculating equilibrium still. The experimental data of the binary systems were verified thermodynamically consistent by the Herington method. NRTL and UNIQUAC models were used for correlating and estimating the measured binary data. The estimated binary VLE results agreed well with the experimental data, and the UNIQUAC model was slightly better than NRTL. Therefore, the UNIQUAC model parameters of the binary systems were used to predict the ternary VLE data. The predicted ternary values are consistent with the experimental results. The average absolute deviation (AAD) of the predicted temperature is 1.37 K and the AAD of the vapor phase compositions is less than 3%, which shows satisfactory prediction for this ternary system.关键词
