Different Units in a Refinery

A refinery is a complex industrial facility that processes crude oil into various petroleum products. It consists of numerous interconnected units, each performing a specific function. Here are some of the key units found in a typical refinery:

Crude Oil Distillation Units:

  • Atmospheric Distillation Unit (ADU): Separates crude oil into various fractions based on their boiling points, such as gasoline, kerosene, diesel, and residual oil.
  • Vacuum Distillation Unit (VDU): Further processes the residual oil from the ADU to produce heavier products like lubricating oils and asphalt.

Conversion Units:

  • Catalytic Cracking Unit (CCU): Converts heavy hydrocarbons into lighter products like gasoline and olefins.
  • Hydrocracking Unit: Converts heavy hydrocarbons into lighter products using hydrogen.
  • Catalytic Reforming Unit (CRU): Converts low-octane gasoline into high-octane gasoline for use in modern engines.
  • Alkylation Unit: Combines olefins with isobutane to produce alkylate, a high-octane component of gasoline.

Treatment Units:

  • Hydrotreating Unit: Removes sulfur, nitrogen, and other impurities from petroleum products.
  • Sweetening Unit: Removes mercaptans (sulfur compounds) from gasoline to improve its odor.

Other Units:

  • Sulfur Recovery Unit (SRU): Recovers sulfur from the refinery's waste gases.
  • Utilities Unit: Provides essential services like steam, water, and electricity to the refinery.
  • Storage Tanks: Store crude oil, intermediate products, and finished products.

Unlocking the Heart of Refineries: Major Equipment in an Atmospheric Distillation Unit (ADU) Explained!

Image
Major Equipment in Atmospheric Distillation Unit (ADU) The Atmospheric Distillation Unit (ADU) is the primary processing unit in most oil refineries. It separates crude oil into various fractions based on their boiling points. The following are the key pieces of equipment found in an ADU: 1. Crude Oil Preheat Furnace: Purpose: Heats the crude oil to a temperature close to its boiling point before it enters the distillation column. Type: Typically, a fired heater that uses fuel gas or oil to generate heat. 2. Atmospheric Distillation Column: Purpose: Separates the heated crude oil into different fractions based on their boiling points. Components: Tray or Packing: Used to provide contact between the vapor and liquid phases. Reboilers: Heat the bottoms product to generate vapor. Condenser: Cools the vapor to condense it into liquid. 3. Fractionators: Purpose: Further refine certain fractions (e.g., naphtha, kerosene) to meet specific product specifications. 4. Strippers: Purpose: ...

  Knowledge Sharing #5 What is the purpose of Atmospheric Distillation Column in atmospheric distillation unit of an oil refinery? The Atmospheric Distillation Column in an oil refinery is a crucial piece of equipment that separates crude oil into various fractions based on their boiling points. It's the first major step in the refining process. Key Purposes: Initial Separation: The column separates crude oil into different fractions, such as light ends (gases), naphtha, kerosene, diesel, and residual oil. Product Production: These fractions are the building blocks for many refined products like gasoline, jet fuel, diesel fuel, and heating oil. Further Processing: Some fractions may require additional processing, like cracking or reforming, to produce specific products. Waste Reduction: By separating the components, the column helps minimize waste and optimize the use of the crude oil. How it Works: Heating: The crude oil is heated to a high temperature and then introduced in...
