In the next stage of refining, these gas oils are further refined to make products such as light-cycle oil (a type of distillate), gasoline, and naphtha. One such refining process is fluid catalytic cracking, which will be the topic of the next refining article in Today in Energy. Steam distillation is an alternative method of achieving distillation at temperatures lower than the normal boiling point. Above this temperature, the oil will thermally crack, or break apart, which impedes the distillation process. The vacuum is critical for separating the VGO from vacuum resid to provide feed separately for the cracking units (FCC and hydrocracking) and deep ⦠Cookiesï¼ We use cookies to optimize this website and continuously update it according to your needs.

Atmospheric and Vacuum Distillation Units Contact Us Locations Share This Serving as the first step in refining crude oil, atmospheric distillation units are responsible for separating fractions of crude oil such as lighter gases (C1-C4), naphtha, kerosene, gasoline, diesel, and fuel oil. As lighter products are boiled off, the heavier oils, called bottoms, remain at the bottom of the ADU. Prime objectives of use of distillation can be either solvent recovery or purification of a mixture component to desired purity level. At low pressures, the boiling point of the ADU bottoms is low enough that lighter products can vaporize without cracking, or degrading, the oil.

Sales, revenue and prices, power plants, fuel use, stocks, generation, trade, demand & emissions. The vacuum is produced through the use of steam ejectors or vacuum pumps pulling a vacuum on the top of the distillation column. Vacuum distillation is the process of lowering the pressure in the column above the solvent to less than the vapor pressure of the mixture, creating a vacuum, and causing the elements with lower vapor pressures to evaporate off. Vacuum Distillation Unit (VDU): further distills the residue oil from the bottom of the crude oil distillation unit. Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation.
