Compressor Station
A station along a gas pipeline that raises the pressure of the gas to keep it moving.
What it does
Friction drops the pressure as gas flows, so compressors restore it at intervals. Hilly terrain needs stations closer together than flat terrain.
Basics
| Handles | Gas |
| Typical spacing | About 40 to 100 miles (65 to 160 km), set by terrain |
| Raises | Line pressure lost to friction |
Common failures
- Liquids carried into the compressor suction
Troubleshooting
- Symptom
- Compressor damage or trips with liquid in the suction
- Likely cause
- Liquid carried past the suction scrubber
- What to check
- Check the scrubber level and drains before restarting
