Production of Bio-LNG vehicle fuel - directly from raw biogas
To transform raw biogas into a valuable fuel for heavy vehicles, Cryo Pur has developed the first integrated solution for biogas upgrading and biomethane liquefaction. Highly efficient for a wide range of flowrates, it also offers the option to produce liquid bio-CO2.
Liquefaction of biomethane or natural gas
In order to be used as a fuel by long-haul trucks, methane must be delivered in liquid form at low pressure and very low temperature. The Cryo LNG solution enables to liquefy upgraded biomethane, grid gas or boil-off-gas with optimum efficiency for a range of micro-scale flowrates.
Production of LNG as an alternative to flaring gas at oil production sites
Adapted to the recovery of associated gas at small-scale oil wells, the Cryo Flare solution enables to eliminate flare gas and to create extra revenues by producing LNG (and LPG) which can be easily transported and sold to remote markets. It is an environment-friendly alternative to routine flaring of small gas quantities.
Production of biomethane from landfill gas (LFG)
Landfill gases contain up to 20-30% of air, which makes them more complex to upgrade. Cryogenic distillation allows to efficiently remove nitrogen and oxygen from biomethane, allowing Cryo Pur to offer a unique solution to landfills aiming at producing upgraded biomethane, in gaseous or in liquid form.
Production of liquid biomethane for remote injection or combustion
For the biogas production sites with no access to the natural gas grid, the Cryo Pur process allows to produce biomethane in liquid form, easy to store and to transport to an injection site, an industrial site or a compressed Vehicle Gas station.
Production of gaseous biomethane for injection into the gas grid and production of liquid bio-CO2
Thanks to its unique CO2 frosting/defrosting process, the Cryo Pur system combines efficiently biogas upgrading and production of high-purity CO2 in liquid form. It offers a solution adapted to projects aiming at valorizing both gaseous biomethane and liquid bio-CO2.
A broad product range
Cryo Pur technology is adapted to biogas projects with flows ranging from 200 Nm3/h to 2 000 Nm3/h raw biogas.
