Compressors for Gas Storage (Injection & Withdrawal)

These compressor units are used to boost natural gas from the pipeline network and inject it into underground storage reservoirs. During peak demand periods, the stored gas is withdrawn to balance seasonal supply and demand fluctuations.

Medium: Pipeline natural gas
Speed: 1000 rpm
Power: 2800-6000 kW
Inlet Pressure: 4-7 MPa
Discharge Pressure: 25-42 MPa
Gas Flow Rate: 60-200×10⁴ m³/d

• The compressor unit features a high-speed, short-stroke, direct-drive design. Under equivalent compression power, the system offers a significantly compact footprint and reduced weight, enabling a fully integrated skid-mounted configuration.
• Engineered with wide gas passages and naturally cooled cylinders to minimize gas pulsation and pressure drop. Custom-designed valves, featuring arc-shaped sealing surfaces and integrated damping plates, ensure high efficiency and extended service life under demanding field conditions.
• The compressor system supports dual operating modes for both gas injection and withdrawal. An integrated manual or electrically controlled clearance volume adjustment system allows for precise and flexible regulation of discharge capacity.
• The application of advanced gas pulsation and mechanical vibration control technologies ensures minimal unit vibration and exceptionally stable operation, even under high-load conditions.
• Equipped with a PLC-based redundant control system. Optional remote monitoring and fault diagnosis modules are available, enabling one-touch start-up and fully unattended operation.
