Bright Biomethane constructed a PurePac Arctic Medium installation in Lohya near Helsinki. The system facilitates production of Renewable Natural Gas from biogas, which is produced from various waste residues.
This system produces 315 SCFM of RNG (506 Nm³/hr biomethane) from 486 SCFM biogas (780 Nm³/hr raw biogas). The produced RNG is directly injected into the national grid and supplies Finnish households with green gas, used for cooking and heating. Alternatively, the produced gas can also be used as CNG (vehicle fuel).
In addition to the production of RNG, the system can also be extended with a Bright CO₂-liquefaction system to recover and liquefy the CO₂.
