Top energy efficiency

Gain maximum efficiency from energy recovery on the turboexpander side of the machine. Use this energy for driving the compressor side

Technical description Compander (TM)

Our Compander (TM) handles all gases and delivers volume flows of up to 480 000 m3/h over 8 stages, operating at a rated power of up to 30 MW. It’s a solution that meets key needs in many of today’s industrial processes, where energy efficiency is the name of the game. Utilizing the full energy recovery potential for combined compression and expansion processes, the compander merges our long standing know-how in integral gear technology and turbo expanders into one solution. It’s unique in that compressor and expander stages are housed in one gear box. You can use the energy recovered on the turboexpander side to power the compressor’s energy cycle, significantly reducing the compressor’s energy consumption (rotor drive).

Our nitrogen and methane companders can be used in different LNG and chemical applications, respectively:

  • nitric acid
  • HPPO
  • caprolactam
  • phenol
  • boil off gas reliquefaction
  • nitrous oxide
