Small Scale Natural Gas Liquefaction

The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C (−260 °F).

Through its StarLiteLNG™ family product, Cryostar also offers land-based small scale liquefaction units to monetize various natural gas sources like associated and stranded gas, coal beds/coal mines, flare gas and biomethane.


A simple, robust and easy-to-operate process with a nitrogen reverse Brayton closed loop, is based on Cryostar and Linde’s proven technology and equipment. Units are available in the 28~200 tpd range.
