Turbo-Brayton for small-scale methane liquefaction

A reliable and efficient solution for biomethane and natural gas liquefaction

This technology allows the production of liquified biomethane (or bio-LNG), a renewable fuel for heavy-duty vehicles and the maritime industry.

Air Liquide Turbo-Brayton for small-scale methane liquefaction is a highly efficient solution combining performance, reliability and compactness.

It can be used for liquefying

  • Biomethane,
  • Landfill gas,
  • Natural gas,
  • Flare gas.

Developing biogas vehicle fuel in Sweden

Turbo-Brayton range

Key benefits
