Design Philosophy
GE's Frame 20 expander is designed to run continuously, year after year, in extreme conditions with the primary objective of reliability and ease of operation. Wheels are milled to computer-generated profiles, customized for performance and efficiency, dynamically balanced, and overspeed tested for integrity.
Applications
Typical applications include:
- Cryogenic Natural Gas Processing - NGL & Ethane recovery, dew point control, LNG production
- Petrochemical - LPG, Ethylene recovery, MTBE & CO processing
- Energy Recovery - Pressure let down, geothermal power generation, tail gas
Testing Capabilities
Our modern test facilities are instrumented with real time data acquisition systems and are capable of testing in accordance with ASME PTC10 Class I, II, or III. GE can perform full load/speed tests with virtually any gas mixture along with performance mapping.
Performance & Product Characteristics
The Frame 20 expander is custom designed for peak performance
at a specified design condition. In addition, a unique
patented Inlet Guide Vane (IGV) controls the turboexpander
gas flow in order to maintain high efficiency over a
wide range of operating conditions. The wheels can withstand
any amount of liquid formation. Oil or Active Magnetic
Bearings are available.
GE can provide expander and compressor housings capable
of pressures up to 200 bar absolute (3000 psia). Expander-generators
can be configured with direct-drive, external gearbox,
or internal gearbox.
