The large-scale Coke Oven Gas (COG) to Methanol unit requires an extremely stable and reliable industrial cooling system. Located in Northern China, the project site presents significant environmental and technical challenges:
| Key Parameter | Specification Details |
|---|---|
| Cooler Type | Forced Draft Air Cooled Heat Exchanger |
| Design / Operating Pressure | 6.4 MPa / 5.2 MPa (High-Pressure Stage) |
| Inlet / Outlet Temperature | 135°C / 45°C (Summer Design Condition) |
| Finned Tube Type | ASME SA179 KL-Type (Knurled L-Foot) |
| Automation System | VFD Speed Control + Automatic Louver System |
| Total Heat Exchange Area | > 12,000 m^2 |
The image showcases the Forced Draft Air Cooling System engineered by Yuhong Group for the project. By positioning the fan system beneath the SA179 finned tube bundles, the design facilitates easier ground-level maintenance. Furthermore, it protects the fans and drive components from direct exposure to hot exhaust air, ensuring the long-term operational reliability of critical parts in extreme polar-cold climates.
