Turboexpander-compressor
with oil bearings. A variety
of models are also
available with active
magnetic bearings.
Typical applications
Floating LNG: turboexpander-compressors offer lighter weight, •
more compact and more efficient refrigeration cycles for the
liquefaction of natural gas
Liquefied petroleum gas (LPG)/natural gas liquids (NGL): •
turboexpander-compressors provide energy-efficient cryogenic
refrigeration for more complete removal of condensates (LPG or
NGL) from hydrocarbon gas streams
Ethylene: turboexpander-compressors increase the overall •
plant efficiency by tail gas refrigeration and subsequent fuel gas
recompression
Dew point control: turboexpander-compressors chill gas streams •
for the removal of moisture to provide dry gas or to control the
heating value of fuel gases
