Steam Heated Shell-and-Tube Heat Exchanger For Viscous Oil Applications
VRCOOLER designs and manufactures shell-and-tube heat exchangers for heavy oil preheating applications. In this system, steam is used as the heating medium to raise the temperature of viscous crude or fuel oil before it enters pumps, filters, or combustion equipment. Proper heating reduces oil viscosity, ensuring smooth flow and efficient atomization during combustion or process use.
Working Principle
The shell-and-tube heat exchanger consists of a bundle of tubes enclosed within a cylindrical shell.
- Steam is introduced into the shell side.
- Heavy oil flows through the tubes in a counterflow direction.
As the steam condenses on the outer surface of the tubes, it transfers latent heat efficiently to the heavy oil flowing inside, increasing its temperature to the desired operating level. The condensate is discharged through a drain system, ensuring continuous operation and stable temperature control.
Advantages
Efficient Heat Transfer: Steam condensation provides high thermal efficiency and uniform heating.
Reliable Operation: Sturdy design suitable for continuous industrial duty.
Easy Maintenance: Tube bundle design allows easy removal for cleaning and inspection.
Customizable: Designed based on specific flow rate, temperature rise, and process conditions.
Durability: Material selection suitable for high-viscosity and corrosive oil environments.
Applications
Fuel oil heating before burner systems in power plants or boilers
Crude oil or bitumen is heated in the refinery and petrochemical industries
Marine fuel oil conditioning systems
Asphalt or heavy lube oil preheating systems
Conclusion
A shell-and-tube heat exchanger for steam heating of heavy oil is an essential component in many industrial systems that handle viscous hydrocarbons.
VRCOOLER provides custom-engineered heat exchangers to ensure efficient, safe, and reliable heating performance tailored to each application's requirements.
