Turboexpanders

We supply a full range of high-performance turboexpanders engineered for critical energy-recovery, gas processing and cryogenic applications in the oil, gas and petrochemical industries. Our systems are designed for maximum efficiency, long-term reliability and safe operation under demanding conditions such as high pressure, high speed and ultra-low temperatures. With deep technical expertise and hands-on project experience, we support customers through selection, engineering, installation and lifecycle operation of expander packages.

Generator-Loaded Turboexpanders
01

Generator-Loaded Turboexpanders

Generator-loaded expanders convert excess pressure energy into electrical power. They are ideal for recovering energy in pipeline pressure let-down systems, gas distribution networks, and industrial waste-energy recovery applications.

Key Applications:

  • Pipeline pressure let-down systems
  • Gas distribution networks
  • Industrial waste-energy recovery

Units can operate independently or integrate directly into plant electrical systems, supporting both operational efficiency and sustainability objectives.

Magnetic Bearing Turboexpanders

Magnetic Bearing Turboexpanders

Magnetic bearing turboexpanders represent the highest level of performance and reliability in expander technology. They operate without physical contact between the rotor and bearings, using active magnetic fields to suspend the rotating shaft.

Key Applications:

  • Oil-free, high-speed operation
  • Active control & real-time monitoring
  • Superior cryogenic performance
  • Compact packaging & simplified installation
  • Safety & reliability architecture

Oil-Free, High-Speed Operation

The oil-free design eliminates the need for lubrication systems and removes the risk of contamination. Benefits include minimal maintenance requirements, extremely low vibration, high rotational speeds, rapid start/stop capability, and longer equipment lifespan.

Active Control & Real-Time Monitoring

Magnetic bearing systems actively control rotor position with micrometer precision. Built-in sensors and control electronics deliver continuous vibration monitoring, automatic rotor stabilization, enhanced safety during process upsets, and predictive maintenance insights.

Superior Cryogenic Performance

Magnetic bearing expanders excel in low-temperature duties such as LNG and FLNG units, ethylene and propylene refrigeration cycles, nitrogen rejection, and mixed refrigerant systems. Their friction-free operation delivers exceptional thermodynamic efficiency.

We have extensive experience supplying, commissioning and supporting magnetic bearing expander systems for complex gas processing and cryogenic applications.

Process Gas Turboexpanders

Process Gas Turboexpanders

Process gas turboexpanders convert the energy of high-pressure gas into mechanical work while simultaneously reducing gas temperature. This controlled expansion is essential for NGL extraction, LPG and LNG production, gas dehydration, cryogenic separation, and pressure let-down energy recovery.

Key Applications:

  • NGL extraction
  • LPG and LNG production
  • Gas dehydration
  • Cryogenic separation
  • Pressure let-down energy recovery

Custom impeller designs, advanced shaft dynamics and efficient sealing systems ensure stable, vibration-free performance even under challenging operating conditions.

Compressor-Loaded Turboexpanders

In compressor-loaded configurations, the expander shaft directly drives a compressor, eliminating the need for an external motor. This significantly improves overall plant efficiency and reduces operational costs.

Applications:

  • Recompression of low-pressure gas streams
  • Refrigeration cycles
  • Hydrocarbon separation processes

These integrated expander-compressor units are engineered for high reliability and optimized thermodynamic performance.

5

Cryogenic Turboexpanders

Cryogenic turboexpanders are designed for extremely low-temperature hydrocarbons and inert gases. They play a central role in LNG liquefaction, mixed refrigerant cycles, deep ethane and propane recovery, and nitrogen rejection units.

Applications:

  • LNG liquefaction
  • Mixed refrigerant cycles
  • Deep ethane and propane recovery
  • Nitrogen rejection units

Optimized wheel geometry, specialized metallurgy and high-precision sealing ensure performance and reliability in harsh cryogenic environments.
