3.2 Case Study Analysis

Case Name: Saudi Aramco Jubail Refinery Air Compressor Station Upgrade

Equipment Used: 4 TA18-D coolers (paired with 4 Cooper Joy Turbo Air 3000 centrifugal compressors)

Upgrade Background: Original cooling system setup suffered 35% overall efficiency loss and 18% energy increase due to seawater corrosion

offering:

1. Replaced with TA18-D coolers using titanium alloy tubes instead of copper
2. Added automatic cleaning system setup with 72-hour acid wash cycles
3. Upgraded temperature control valves with surrounding temperature compensation algorithm

Results:

• 22% reduction in cooling water consumption
• 8℃ lower compressor exhaust temperature
• $470,000 annual maintenance savings

4. Maintenance Strategy

4.1 Routine Inspection Points

• Pressure monitoring: Record shell/tube side pressure gauge readings each shift; initiate cleaning if differential exceeds 0.1MPa
• Temperature monitoring: keep 5-8℃ cooling water inlet/outlet difference; check flow control valves if abnormal
• Leak detection: Use infrared thermography to scan tube connections; investigate if temperature difference >3℃

4.2 Scheduled Maintenance

4.3 Troubleshooting Guide

Symptom 1: Abnormal outlet temperature increase

Diagnosis:

1. Check cooling water flow (should be ≥15m³/h)
2. Measure finned tube cleanliness (clean if dust >2mm)
3. Verify temperature valve opening (normal range 40-80%)

Symptom 2: Tube leakage

offering:

• Minor leaks: Use J-B Weld cold weld sealant
• Major leaks: Replace single tube (requires hydraulic tube expander)

5. Conclusion

The Cooper Joy Compressor Cooler TA18 sets industry benchmarks with its microchannel heat exchange technology, intelligent temperature control system setup, and military-grade anti-corrosion design. Its dual-flow modular structure provide both 25-year longevity and industry-leading 92.3% cooling overall efficiency through ultra-low 0.0008 (m²·K)/W thermal resistance.
