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.
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
- 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. Typical applications include:
- 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.
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
- Industrial waste-energy recovery
Units can operate independently or integrate directly into plant electrical systems, supporting both operational efficiency and sustainability objectives.
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
- Nitrogen rejection units
Optimized wheel geometry, specialized metallurgy and high-precision sealing ensure performance and reliability in harsh cryogenic environments.
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. We have extensive experience supplying, commissioning and supporting magnetic bearing expander systems for complex gas processing and cryogenic applications.
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
- Longer equipment lifespan
This makes magnetic bearing expanders ideal for ultra-clean and cryogenic services.
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
- Predictive maintenance insights
These features extend availability and improve operational integrity across the plant.
Superior Cryogenic Performance
Magnetic bearing expanders excel in low-temperature duties such as:
- LNG and FLNG units
- Ethylene and propylene refrigeration cycles
- Nitrogen rejection
- Mixed refrigerant systems
Their friction-free operation delivers exceptional thermodynamic efficiency and stable long-duration performance.
Compact Packaging & Simplified Installation
The absence of a lube-oil system reduces auxiliary equipment, footprint and commissioning time. This compact design is especially valuable in:
- Offshore platforms
- Modular plants
- Remote facilities
- Skid-based installations
Fewer components translate to a lower total cost of ownership over the unit's working life.
Safety & Reliability Architecture
Magnetic bearing expanders include:
- Redundant control electronics
- Touchdown bearings for emergency events
- Automatic shutdown protection
- Real-time diagnostics
This robust architecture ensures maximum uptime and safe operation under all plant conditions.
Bearings & Sealing Technologies
Across all expander types, a range of bearing and sealing systems is available to match process requirements:
Engineering, Packaging & Lifecycle Support
Each turboexpander package can be supplied as a fully integrated skid, complete with all mechanical, electrical, control and auxiliary systems, including:
- Control panels and PLC/DCS integration
- Seal-gas and instrumentation systems
- Testing and performance verification
- Commissioning and start-up
- On-site training and technical support
- Long-term maintenance and troubleshooting
Our engineering team ensures each unit is precisely matched to the customer's process conditions, project specifications and reliability expectations.
