Crucial Role of Strippers in Atmospheric Distillation Unit of Oil Refinery:



Strippers are essential components in atmospheric distillation units (ADUs) of oil refineries. Their primary function is to improve the separation efficiency of different hydrocarbon fractions within the crude oil.

How Strippers Work

  1. Side Streams: Strippers are typically installed at various points along the distillation column, often at side streams where specific hydrocarbon fractions are drawn off. These fractions, such as kerosene or diesel, may contain impurities or lighter components that can affect their quality.
  2. Steam Injection: Steam is injected into the stripper at the bottom. This steam acts as a stripping agent, reducing the partial pressure of the hydrocarbons in the liquid phase. This lower partial pressure encourages the lighter components, such as gasoline or naphtha, to vaporize.
  3. Separation: The vaporized lighter components are then separated from the heavier liquid fraction and returned to the distillation column, improving the overall separation efficiency. This process ensures that the final products meet the desired specifications.

The Importance of Strippers

Strippers play a crucial role in:

  • Product Quality: By removing impurities and lighter components, strippers help ensure that the final products, such as gasoline, kerosene, and diesel, meet the necessary quality standards for use.
  • Yield Optimization: Strippers can increase the yield of valuable products by maximizing the recovery of lighter components from the heavier fractions.
  • Energy Efficiency: Strippers can help improve the energy efficiency of the overall distillation process by reducing the amount of energy required to achieve the desired separation.

In conclusion, strippers are essential components in atmospheric distillation units, providing a vital function in ensuring the efficient and effective separation of hydrocarbon fractions in the refining process.

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...
