What is the Process that undergoes in Oil Preheating Furnace?
Crude Oil Entry: The desalted crude oil, which has already been heated and mixed with water to remove salt, enters the preheating furnace.
Heat Exchange: The furnace is typically designed with a series of tubes through which the crude oil flows. Hot flue gases, generated by burning fuel (such as natural gas or fuel oil), pass over these tubes, transferring heat to the crude oil.
Temperature Increase: As the crude oil flows through the tubes, it absorbs heat from the flue gases, gradually increasing in temperature.
Desired Temperature: The furnace is carefully controlled to ensure that the crude oil reaches the desired temperature, typically around 350°C to 360°C. This temperature is essential for effective vaporization of the lighter components in the crude oil.
Exit to Distillation Column: Once the crude oil has reached the target temperature, it exits the preheating furnace and enters the atmospheric distillation column, where the separation process begins.
