| Abstract: | 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. |
