Field Parameters and Operation Guidelines for Large Reciprocating Gas Compressors
Large reciprocating gas compressors are widely used in industries such as oil & gas, chemical processing, nitrogen generation, oxygen production, and high-pressure gas applications.
Proper parameter monitoring and standardized operation are essential to ensure safe, efficient, and long-term performance.
1. Key Operating Parameters
Inlet Conditions
- Inlet Pressure (kPa / MPa)
- Inlet Temperature (°C, within 1m of cylinder inlet)
- Filter Differential Pressure (>6 kPa requires maintenance)
Cylinder Performance
- Discharge Pressure
- Discharge Temperature
- Vibration Level
- Piston Rod Drop
Auxiliary Systems Lubrication System
- Oil Pressure / Temperature
- Filter Differential Pressure
Cooling System
- Water Inlet / Outlet Temperature
- Water Pressure
Drive System
- Motor Current / Power
- Speed (RPM / Hz for VSD)
2. Daily Operation Procedure (8 Steps)
- Pre-start inspection
- Start-up (no-load → warm-up → load)
- Hourly monitoring
- Drain and condensate management
- Lubrication control
- Vibration monitoring
- Normal shutdown
- Emergency shutdown
3. Emergency Shutdown Conditions
- Discharge temperature >160°C
- Oil pressure <0.15 MPa
- Excessive vibration (>18 mm/s)
- Gas leakage
4. Common Mistakes
- Tightening under pressure
- Frequent start/stop cycles
- Failure to drain water in winter
5. Integrated Gas System Solution
This compressor system is commonly integrated with:
- Reciprocating Gas Compressors
- PSA Nitrogen Generators
- PSA Oxygen Generators
- Air Dryers and Filtration Systems
