The refining of crude oil begins with distilling the of a petroleum refinery vacuum distillation  In modern refinery practice the distillation of atmospheric residue is accomplished under high vacuum conditions in a specially designed tower whose internal 

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),  16 Jul 2013 A strain of biosurfactant producing bacterium was isolated from an oil contaminated soil at Tehran refinery distillation unit. Based on selected  28 Feb 2019 Albeit, different refining unit are subsets of the physical separation category. The atmospheric and vacuum distillation unit seems to be more  Main schemes for crude oil fractionation. OPERATING CONDITIONS OF AN ATMOSPHERIC & VACUUM DISTILLATION UNITS. Material balance: cut points,   31 Aug 2015 Oil And Gas Wiki » Introduction To Refining » Vacuum Distillation Unit The process takes place in one or more vacuum distillation towers.

A crude oil refinery is a group of industrial facilities that turns crude oil and other inputs into finished petroleum products. A refinery's capacity refers to the maximum amount of crude oil designed to flow into the distillation unit of a refinery, also known as the crude unit.

Vacuum Distillation Unit (VDU): further distills the residue oil from the bottom of the crude oil distillation unit. The vacuum distillation is performed at a pressure well below atmospheric pressure. The vacuum distillation unit is widely used to separate substance that decomposed, oxidized or polymerized Vacuum Distillation. After gas oil stripper, the oil is sent to the vacuum Distillation to recover vacuum distillate oil fraction which is heavier than the Contaminants. Vacuum distillation is the technique used to separate higher boiling fractions of crude oil. The underlying theory and the process are analogous to those used to separate the lighter fractions in the atmospheric distillation process. The heaviest and the most contaminated component of crude oil is the vacuum distillation residue (VDR), also referred to as the bottom-of-the-barrel. There are multiple processing paths to upgrade VDR into usable products. One process is called deasphalting, which removes the heaviest fraction of VDR as asphalt that is used mainly to pave roadways.

Vacuum Residue. This is the bottom product from the vacuum distillation unit. Just as in the case of the atmospheric residue it has several options for its use in meeting the refinery’s product slate. In the case of the energy refineries it can be upgraded to prime distillate products by a recycling thermal cracking process, coking, •Salt present in the emulsified water •Treated in the field with heat & chemicals to break oil water emulsions. •Oil mixed with fresh wash water & demulsifiers. Partial condenser if no Stabilizer Column. Total condenser if Stabilizer Column to remove light ends.
