After desalting, the crude oil enters a distillation column where distillation separates the hydrocarbons into different distillation sections, cut-offs, or fractions. In order to separate mixed liquids, the principle of different volatility (boiling point) of different liquids under different conditions is used for liquid separation, so as to achieve the purification effect.

Challenge:

Level control must cope with foaming, foaming and moderate to high temperatures.
