Gas Compression

« Back to Glossary Index« Back to Previous Page

Definition:
The process of increasing the pressure of natural gas to facilitate transportation through pipelines, improve processing efficiency, and enhance storage.

Key Components:

  • Reciprocating Compressors: Use pistons to increase gas pressure.
  • Centrifugal Compressors: Utilize high-speed rotating impellers to compress gas.
  • Screw Compressors: Use meshing helical screws for continuous gas compression.
  • Compressor Stations: Facilities along pipelines to maintain pressure over long distances.

Use Cases/Industries:

  • Pipeline Transportation: Moves gas efficiently across long distances.
  • Gas Processing Plants: Enhances separation and treatment efficiency.
  • Underground Storage: Compresses gas for storage during low-demand periods.

Advantages:

  • Efficiency: Reduces transmission losses in pipelines.
  • Increased Capacity: Allows more gas to flow through existing infrastructure.
  • Operational Control: Ensures stable pressure for downstream processes.

Challenges:

  • Energy Consumption: Compressors require significant power input.
  • Maintenance Needs: Moving parts require regular inspection and servicing.
  • Environmental Impact: Compressor stations can be sources of methane leaks.

Related Terms:
Pipeline Boosting, Pressure Regulation, Gas Transmission

Example:
A gas pipeline network uses compressor stations every 50 miles to maintain optimal flow rates and pressures.
