Turbo-Expander Compressors

Turbo-Expander Compressors

Delivering reliable cryogenic service with ultra-high energy efficiency in virtually any oil and gas application

Robust materials and advanced designs that result in smaller footprints and higher performance for the most demanding applications

  • BHGE turboexpander-compressors are used industry-wide for reliable refrigeration service and high plant energy efficiency. We provide the frame sizes, capacities, footprints and weights to match virtually any application. With over 60 years of experience, our global installed base includes the industry’s first turboexpander-compressor used for GTL, first NACE-compliant active magnetic bearings (AMB), and first AMB installed on an FPSO.

    Our latest advances include more compact liquefaction solutions for Floating LNG, better condensate removal for LPG and NGL, tail gas and fuel gas solutions that increase ethylene plant efficiency, and improved moisture removal for dew point control.

    Key design features include AMBs that are fully NACE compliant for sour-gas service; expander casings that are CFD-optimized for minimal flow distortions, with special zero-leakage solutions available for sour and toxic gases; a nozzle assembly that’s mechanically designed to withstand liquid droplets and solid particles; and expander wheels milled from single-piece aluminum, titanium alloy or stainless steel for light weight and exceptional rotor-dynamic stability.
