Distillation columns are one of the most commonly used thermal separation units and have been used for many centuries.
Their operation is based on the difference in boiling temperatures of the liquid mixture components, and on recycling counter-current gas-liquid flow.
The properly organized temperature distribution up the column results in different mixture compositions at different heights.
While multi-component is a common phenomenon for all column types, the flow regimes are very different depending on the internal elements used.
The two main types are a tray column and a packed column, the latter equipped with either random or structured packing.
