Turboexpander-compressors Increased efficiency for refrigeration applications

Turboexpandercompressors Turboexpanders are used in all segments of the oil and gas industry to produce cryogenic refrigeration, while increasing the facility’s energy efficiency and reducing its CO2 footprint. Alternative approaches include expansion of the gas stream through a valve, which does not recover energy, and external refrigeration, which consumes energy. A turboexpander, on the other hand, is a pressure let-down device that produces cryogenic temperatures while simultaneously recovering energy from a plant stream in the form of shaft power that can be used to drive other machinery...

Typical applications • Floating LNG: turboexpander-compressors offer lighter weight, more compact and more efficient refrigeration cycles for the liquefaction of natural gas • Qatar Shell Pearl: first GTL turboexpander-compressor (Frame 60, 13,900 HP) • 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...
