For higher power levels and pressure ratios with lower maintenance requirements in oil and gas and energy recovery applications
Our turboexpander-generator designs respond to specific industry needs for increased capacity, reduced costs, and maximized reliability in a wide range of fullstream and low carbon applications. Our fleet ranges from 0.3 to 20 MW with a proven record of performing at extreme temperature and pressure conditions, delivering the highest power level.
In 2019, we delivered a new concept for turboexpander generator designed to convert the natural gas pressure energy into electricity as the main component of our Heat Injection Pressure Energy Recovery (HIPER) system—an optimized natural gas waste-pressure recovery system for pressure reduction stations.
Our 300 kW HIPER system fully assembled.
Rated for 85 barA pressure, this 300 kW expander is a single-shaft machine directly coupled with a high-speed generator at 30,000 rpm to avoid gearbox and related auxiliaries. This configuration is completely oil free, as it is supported only on magnetic bearings in a totally sealed case, which avoids gas leakage, flares, and vents to atmosphere.
Advantages suggest its adoption in pressure let-down applications either as a single machine or a whole system, as long as process data are compatible.
17 MW double-stage expander generator ready for shipment.
We have manufactured three large 17 MW double-stage expander generators. Two are operating in Canada and Brunei at waste-heat recovery plants based on our organic rankine cycle (ORC) to recover gas turbine exhaust heat.
The design is based on two integrally geared stages, the largest having a 1,000 mm diameter impeller, and a multi-link inlet guide vane system suitable for high process gas temperature, up to 315°C design temperature.
Regardless the required installation, the design can guarantee the same high performance in either a cold or tropical environment.
Our ORC expander generator installed in Brunei.
