Air Cooler According to API 661 and ASME SEC VIII Div-1, Petrochemical and Oil Refineries Application
Advantages of Air Coolers in Oil Refineries:
1. Water Conservation: Unlike water-cooled systems, air coolers do
not require large amounts of water.
2. Cost-Effective: Lower operational costs compared to water-cooled
systems.
3. Environmental Friendly: No risk of water contamination or
discharge.
Yuhong Group air cooler for an oil refinery is a critical piece of
equipment used to cool process fluids, gases, or equipment in
refinery operations. These coolers are essential for maintaining
optimal temperatures, ensuring safety, and improving the efficiency
of refining processes. Below is an overview of air coolers in oil
refineries, including their types, applications, and key
considerations:
Types of Air Coolers Be Used In Oil Refineries:
1. Forced Draft Air Coolers:
- Fans are located at the bottom, forcing air upward through the
finned tubes.
- Suitable for high-temperature applications.
- Easier maintenance as fans are accessible.
2. Induced Draft Air Coolers:
- Fans are located at the top, pulling air through the finned
tubes.
- Better air distribution and reduced hot air recirculation.
- Commonly used in refineries due to their efficiency.
3. Horizontal Air Coolers:
- Tubes are arranged horizontally, and air flows perpendicular to
the tubes.
- Ideal for cooling large volumes of process fluids.
4. Vertical Air Coolers:
- Tubes are arranged vertically, and air flows upward or downward.
- Used in space-constrained areas.
5. V-Shaped or A-Frame Air Coolers:
- Tubes are arranged in a V-shape to maximize surface area.
- Compact design, suitable for high-capacity cooling.
