Mass transfer in distillation column
WebIn the column, liquids tend to wet the surface of the packing and the vapors pass across this wetted surface, where mass transfer takes place. Packing material can be used instead of trays to improve separation in distillation columns.

WebInside the column there are always two phases: one gas phase and one liquid phase. The liquid phase flows downward through the column via gravity, [1] while the gas phase flows upward. These two phases come in contact in correspondence of holes, valves or bubble caps that fill the area of the plates. [2]
