How Molecular Distillation Use

A distillation column can use either trays or packings. Their mechanisms of mass transfer differ, but the key for both is a good approach to equilibrium through the genera-tion of large amounts of interfacial area. This interfacial area results from the passage of vapor through the perforations of trays, or the spreading of liquid on the surface of
