Bright Biomethane constructed a biogas upgrading system in France. The system facilitates production of Renewable Natural Gas from biogas, which is produced from various waste residues.
Next to the MICROFERM+ plant, which is specially designed for on-farm anaerobic digestion of liquid and solid agricultural feedstock, Bright has build a PurePac Compact. A maximum of 7,400 tonnes of mainly cattle manure and maize silage is anaerobic digested annually and produces biogas. Bright’s biogas upgrading system upgrades 62 SCFM of biogas (100 Nm³/hr raw biogas) to 34 SCFM of RNG (55 Nm³/hr biomethane).
The produced RNG is directly injected into the national grid and is used for cooking and heating. Alternatively, the produced gas the could 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.
