Atmospheric and Vacuum Distillation Units | FSC 432: …
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 4.2.
Atmospheric distillation of crude oil - Wikipedia
Atmospheric and vacuum distillation of crude oils are the main primary separation processes producing various straight run products, e.g., gasoline to lube oils/vacuum gas oils. Distillation of crude oil is typically performed first [1] under atmospheric pressure and then under a vacuum.
Understanding the Crude Distillation Unit (CDU) Process from …
The Crude Distillation Unit (CDU), also known as the atmospheric distillation unit, is the primary processing step in refining crude oil. It is responsible for fractionating crude oil into various hydrocarbon products based on their boiling points through a process called fractional distillation .
Atmospheric Distillation Unit - EnggCyclopedia
An atmospheric distillation unit in a crude oil refinery, is used to separate different hydrocarbon components of a crude oil mixture to be used for a variety of applications as products of crude oil refining.
Atmospheric Distillation Unit - an overview - ScienceDirect
Crude distillation unit (CDU) is at the front-end of the refinery, also known as topping unit, or atmospheric distillation unit. It receives high flow rates hence its size and operating cost are the largest in the refinery.
So, we know that an Atmospheric Distillation Unit (or ADU) separates crude oil into gas, light and middle distillate and atmospheric residue fractions. A Vacuum Distillation Unit (or VDU) separates atmospheric residue into heavy distillate and vacuum residue fractions.
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, naphtha, kerosene, diesel and fuel oil.
Atmospheric Distillation - an overview | ScienceDirect Topics
Atmospheric and vacuum distillation units are used to separate volatile products (e.g., naphtha, motor spirit, kerosene, diesel, gas oil, etc.) from desalted crude oil. Atmospheric distillation is employed to separate the lighter hydrocarbons from the crude oil.
