Sorption experiments of the membranes were carried out in water and water-1,4-dioxane azeotropic mixtures
. Total sorption could be obtained by immersing a known weight of the dry membrane in water and it was allowed to attain the equilibrium for 24 h at room temperature.

They address types of column internals and the advantages and disadvantages of equipment used for vapor-liquid contacting and separation; the features of the main types of vapor-liquid contactors, including distillation trays, random packings, and structure packings; equipment design, column configuration, and operation-related aspects of dividing-wall columns; the separation of azeotropic mixtures
in extractive distillation; reactive distillation; the features of vacuum and high-pressure distillation; and laboratory distillation and scale-up.
Pervaporation is a promising separation technique and is becoming recognized as an energy-efficient alternative to distillation and other separating methods for liquid mixtures, especially in cases that the traditional separation techniques are not efficient, such as separating of azeotropic mixtures
[5, 6], isomeric components , and close-boiling point systems .
The reader may remember such terms as temperature glide, azeotropic mixtures
, and zeotropic mixtures (the latter two terms referring to the same characteristic: mixtures whose concentrations change during phase changes).

At shale oil distillation oil components of different nature have close boiling points, and as a result azeotropic mixtures
