The CH4LNG liquefaction system enables obtaining liquid RNG, an ideal solution for those who are not able to access the gas network.
Liquid RNG has significant competitive advantages, including the fact that it is three times thicker than compressed natural gas and that, compared to the latter, it guarantees greater cruising range for vehicles that use it as fuel. It can also be transported with cryogenic tankers, favoring plants that do not have access to the gas pipeline.
The heart of the CH4LNG process is the cryo-cooler, based on Stirling Cryogenics technology, which is an alternative machine that generates cooling power by compressing and expanding helium in a closed cycle.
CH4LNG is a containerized modular solution also available for small and very small sizes: the CAPEX and OPEX models, competitive even for small sizes, with plug-in operation and no N₂ consumption. It is compatible with the BIOCH4NGE® RNG upgrading solution.
