Methane liquefaction

LNG- and LBG product overview

Properties of our systems

ERT supplies compact low-temperature generators based on the Stirling principle which reach temperatures below the condensation point of methane (-162°C / 111 K) within a few minutes. ERT’s StirLNG systems have proven themselves in commercial operation for decades. Individual units can be flexibly combined to form multisystem systems.

StirLNG cryogenerators can be used universally as stand-alone systems even under demanding conditions. They offer very high availability at maintenance intervals of 6,000 operating hours. Other features include high energy efficiency and flexibly controllable capacity. Electrical power consumption and condensing capacity depend on the process and the pressure and temperature of the feed gas.

The application spectrum of our StirLNG cryogenerators includes

  • Methane liquefaction: LNG production from purified natural gas, purified biogas or purified landfill gas
  • Methane reliquefaction: On-board marine systems and stationary systems for boil-off gas management
  • Liquid methane tank cooling: on-board marine and stationary systems for liquid methane subcooling/prevention of roll-over events
  • Process cooling supply for methane gas purification: Conditioning of natural gas, biogas and landfill gas
