What is the main purpose of evacuating a distillation tower?

Reduce the pressure inside the tower, thereby lowering the boiling point of the oil.

Negative pressure distillation is aimed at saving energy consumption and reducing the solubility of impurities

Lower the boiling point to allow the liquid to evaporate at low temperatures

In addition to energy savings and reducing the pyrolysis temperature, the 7th floor explains clearly what other benefits there are to lowering the boiling point of oil products

Under reduced pressure distillation, the lower the pressure, the lower the boiling point of the material, which reduces the amount of heat required and thus saves energy.

Reduce the material extraction (distillation) temperature to avoid material pyrolysis.
