Types of Crude Oil Preheat Furnaces



Crude oil preheat furnaces are essential components in refineries, as they raise the temperature of incoming crude oil before it enters the distillation column. This preheating process improves the efficiency of the distillation process by reducing the viscosity of the crude oil, which allows for better separation of its various components. There are several different types of crude oil preheat furnaces, each with its own unique design and advantages:

1. Vertical Fired Furnaces:

  • Description: These furnaces feature a vertical cylindrical shell with burners located at the bottom. The crude oil flows upward through the furnace, being heated by the flames from the burners.
  • Advantages: Simple design, efficient heat transfer, and relatively low cost.
  • Disadvantages: Can be prone to coking and fouling, especially if the crude oil contains high levels of sulfur or heavy metals.

2. Horizontal Fired Furnaces:

  • Description: Similar to vertical fired furnaces, but with a horizontal orientation. The burners are located at one end of the furnace, and the crude oil flows through the length of the furnace.
  • Advantages: Can handle higher flow rates of crude oil and is less prone to coking and fouling than vertical fired furnaces.
  • Disadvantages: More complex design and higher construction costs.

3. Radiant Fired Furnaces:

  • Description: These furnaces use radiant heat from the combustion process to heat the crude oil. The burners are located in a separate chamber, and the hot gases from the combustion process are directed into the furnace to heat the crude oil.
  • Advantages: Highly efficient heat transfer and can handle a wide range of crude oil qualities.
  • Disadvantages: More complex design and higher construction costs.

4. Convection Fired Furnaces:

  • Description: These furnaces use convection heat transfer to heat the crude oil. The hot gases from the combustion process are circulated through the furnace, transferring heat to the crude oil as they pass over it.
  • Advantages: Can handle a wide range of crude oil qualities and is less prone to coking and fouling.
  • Disadvantages: Less efficient than radiant fired furnaces and can be more expensive to operate.

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...
