Benefits

  • Our high-efficiency designs from ambient down to ensure optimal refrigeration and cooling capacity with substantial energy recovery
  • Zero-leakage design with a low-temperature cryocooler and magnetic bearings, optimized AMB footprint and weight for offshore applications
  • Strong collaboration with SKF on cryogenic engineering and refrigeration systems for AMB optimization, enabling the first AMB for 5.5MW floating LNG
Features

  • Advanced use of cryogenic nitrogen liquefaction and technologies, with verified wheels up to 1,000 mm diameter for large-capacity machines
  • Wide range of sizes up to 15MW supported on AMB or oil bearings with optional dry gas seals for aggressive gas applications
  • Management of energy recovery, coolant and liquefaction turbomachinery, including installation, full-load string testing, start-up, and service
Applications

  • LNG feed-gas treatment (onshore and floating)
  • Cryogenic gas treatment: dew point control, LPG recovery, refrigeration
  • Petrochemical and natural gas: methane, ethylene, syngas, H2 rich process, argon

Complete in-house capabilities

For a 2019 offshore platform project in the North Sea involving seven of our single shaft, high-speed moto-compressors with active magnetic bearings (AMB), we also delivered two AMB expander compressors with dry gas seals (DGS). Service is characterized by high H2S content not compatible with magnetic bearings. Hence, the DGS solution was the only way to enable oil-free configuration in sour service. Assembled and tested in-house, our turboexpander compressors leverage our internal capability for magnetic-bearing tuning and testing resulting from the agreement with SKF.
