Atmospheric distillation in oil refinery - temperature
Crude oil travels from the primary heat exchanger to the atmospheric distillation unit, where it is separated into various ”fractions” or “cuts”, such as fuel gases, LPG, naphtha, kerosene, diesel and fuel oil. A boiler heats and vaporizes crude oil at the bottom of the distillation column.
Atmospheric Distillation Unit - EnggCyclopedia
Atmospheric Distillation Unit (ADU) Crude oil is sent to the atmospheric distillation unit after desalting and heating. The purpose of atmospheric distillation is primary separation of various cuts of hydrocarbons namely, fuel gases, LPG, naptha, kerosene, diesel and fuel oil. The heavy hydrocarbon residue left at the bottom of the atmospheric distillation column is sent to vacuum distillation column for further separation of hydrocarbons under reduced pressure.
Atmospheric and Vacuum Distillation Units | FSC 432
Atmospheric and Vacuum Distillation Units. Print. Distillation of crude oil is carried out in two units, first in an Atmospheric Distillation Unit (also known as Crude Distillation Unit, CDU), with further processing of the residue from atmospheric distillation in the Vacuum Distillation Unit (VDU), as illustrated in Figure hrpalmoilmachine.
Atmospheric Crude & Vacuum Distillation Processes
The Crude Distillation Unit is the first major unit in the refinery. Therefore, it is the first processing unit to be exposed to hot crude oil feedstock and provides feedstock for all of the rest of the units in the refinery. Its purpose is to distill the crude feedstock into various fractions, according to their boiling point ranges.

Atmospheric distillation | Oil Refining
Atmospheric distillation is the first and most fundamental step in the the refining process. The primary purpose of the atmospheric distillation tower is to separate crude oil into its components (or distillation cuts, distillation fractions) for further processing by other processing units.
Crude Oil Atmospheric Distillation - hrpalmoilmachine
The objective of the crude distillation unit is to separate the feed crude blend into different fractions, such as liquefied petroleum gas ), naphtha, kerosene, light gas oil(LPG , and heavy gas oil.
Crude Oil Distillation - an overview | ScienceDirect Topics
The crude oil distillation system consists of an atmospheric distillation unit, in which crude oil is separated into more valuable products, and a heat exchanger network (HEN) which pre-heats the crude oil before it enters the column. The atmospheric distillation unit and the HEN interact with each other, making the retrofit of crude oil distillation systems a complex problem requiring analysis of column hydraulics and HEN performance.
Crude oil distillation and the definition of refinery
Crude oil is first heated and then put into a distillation column, also known as a still, where different products boil off and are recovered at different temperatures. Lighter products, such as butane and other liquid petroleum gases (LPG), gasoline blending components , and naphtha , are recovered at the lowest temperatures.
Crude Oil Separation Processes - Petroleum Refinery Equipment
The main separation step in any crude oil refinery is atmospheric or primary distillation. Atmospheric distillation fractionates the crude oil into various distillates, fractions, or cuts of hydrocarbon compounds based on molecular size and boiling)point range [hrpalmoilmachine., light ends, propane, butanes, straight ) run naphthas (light and heavy), kerosene, straight-run gas oils (light and heavy), and atmospheric residue] (Figure hrpalmoilmachine).
Overview of Crude Units
Crude units are the first units that process petroleum in any refinery. schematic diagram of an atmospheric crude fractionation unit is shown in Figure 1-1. Crude water. HEN Crude oil contains salts which can be harmful to downstream equipment and must be atmospheric column, where the vapor and liquid separate.

Petroleum refining - Vacuum distillation | hrpalmoilmachine
The primary advantage of vacuum distillation is that it allows for distilling heavier the top of crude-oil or process-unit fractionating columns within the refinery. as kerosene or heavy naphtha, in equipment resembling a fractionating column.
Atmospheric Distillation - Maverick Engineering
Crude oil is first processed in a refinery by running it through an Atmospheric Distillation Unit, typically referred to as a Crude Unit, where the crude is split by exchanging heat with some of the hot cuts from the atmospheric distillation column.
Vacuum Distillation - Maverick Engineering
Thus, the residue from the bottoms of the Atmospheric Distillation unit can be piped column operated under vacuum (hrpalmoilmachine PSI), called a Vacuum Distillation unit steam into the tower, and are more applicable to gas oil and fuels production.
