摘　　要：用热力学相平衡理论和UNIFAC模型研究了渗透汽化从C6 溶剂油中脱微量水的可行性 ,用自制的两种膜进行了渗透汽化脱水的小试和扩大试验 ,确定了适合该体系的脱水用膜和脱水工艺条件 .The potentiality of removal of low concentration of water from C\-6 solvent by pervaporation was studied with the help of thermodynamic phase equilibrium theories and the UNIFAC model. Two kinds of dehydration membranes prepared in our laboratory were used in the normal and enlarged pervaporation experiments. The membrane with good dehydration properties and the parameters useful for dehydration process design have been determined in the experiments.
