Genetron AZ-20 is an azeotropic mixture of HFC-32 (hydrofluorocarbon) and HFC-125 (hydrofluorocarbon).
It has been used to separate close boiling liquids and azeotropic mixtures, which are difficult to separate using conventional separation processes, such as distillation [1-4].
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.
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).
