Technology Type

Vacuum Distillation is a part of the Refining process that helps to produce Petroleum products out of the Heavier Oils left over from Atmospheric Distillation. As the name Vacuum Distillation implies, the Distillation Column is under a Vacuum, or significantly less than Atmospheric Pressure of 760 millimeters of Mercury (mmHg). At low Pressures, the Boiling Point of the ADU Bottoms is low enough that lighter products can vaporize without cracking, or degrading, the Oil. Vacuum Distillation produces several types of Gasoil. These are slightly Heavier than Middle Distillates such as Jet Fuel, Kerosene, and Diesel.
