摘要:
实验主要测定了6.67 kPa下乙二醇-1,4-丁二醇-二乙二醇的三元体系气液相平衡数据.使用广泛适用的WILSON、NRTL和UNIQUAC模型对实验数据进行拟合关联,结果表明：实验数据与预测数据之间最大平均相对误差为5.326%,可以满足工程上分离设计的要求.
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.
