Vacuum distillation crude oil
Vacuum distillation in petroleum refining. Petroleum crude oil is a complex mixture of hundreds of different hydrocarbon compounds generally having from 3 to 60 carbon atoms per molecule, although there may be small amounts of hydrocarbons outside that range. Vacuum gas oil, wax distillates, and vacuum residue as an intermediate product for further processing. COBRA screw vacuum pumps and Dolphin liquid ring vacuum pumps are used for the vacuum distillation of crude oil. CRUDE AND VACUUM DISTILLATION 221/1/1 EN APPLICATION REPORT 12/15 3 Fuel gas/oil control The furnaces create the heat required to cause vaporisation of most of the feed entering the atmospheric topping unit. For the vacuum tower, the heat level is kept just below the cracking level of the feed so that the fractions can be separated under low pressure. A variety of fuels can be The residue remaining after vacuum distillation, called bitumen, may be further blended to produce road asphalt or residual fuel oil, or it may be used as a feedstock for thermal cracking or coking units. Vacuum distillation units are essential parts of the many processing schemes designed to produce lubricants.
The system produces and maintains sub-atmospheric pressure (a vacuum) within the distillation column to permit fractionation of crude oil into its various
The heavier the crude processed, the larger the vacuum unit that will be either atmospheric bottoms from the distillation tower or purchased reduced crude. Typically blended into residual fuel oil or upgraded through a coker or visbreaker. The function of a VDU is separation of the atmospheric crude tower residue to produce heavy, medium, and light gas oil as well as a vacuum residue. The distillation process for crude oil is typically performed either under atmospheric pressure or under a vacuum. Low-boiling fractions of crude oil usually Improvement of the energy efficiency of Crude oil distillation process at atmospheric vacuum distillation unit.

All crude oil processed must first go through atmospheric distillation. the bottoms from the atmospheric distillation tower will be sent to the vacuum tower for The heavier the crude processed, the larger the vacuum unit that will be either atmospheric bottoms from the distillation tower or purchased reduced crude. Typically blended into residual fuel oil or upgraded through a coker or visbreaker. The function of a VDU is separation of the atmospheric crude tower residue to produce heavy, medium, and light gas oil as well as a vacuum residue.

NASH liquid ring vacuum pumps and steam ejectors offer reliable, low maintenance solutions for vacuum distillation of crude oil in refinery applications. is used for safety monitoring in vacuum distillation columns in petroleum refining. The vacuum distillation column is used to distill the residual oil from the
Desalting and atmospheric and vacuum distillations of crude oil. Some of the mixed water forms an emulsion that must be demulsified to separate water from oil. Emulsifiers are present in the form of clay, metallic salts, and asphaltenes, whose contents are higher in heavy crude oils.

Vacuum distillation units are essential parts of the many processing schemes designed to produce lubricants. Distillation of crude oil is typically performed either under atmospheric pressure and under a vacuum. Low boiling fractions usually vaporize below 400°C at atmospheric pressure without cracking the hydrocarbon compounds. Therefore, all the low boiling fractions of crude oil are separated by atmospheric distillation. A crude distillation unit (CDU) consists of pre-flash distillation column. The petroleum products obtained from the distillation process are light, medium, and heavy
