Type installationPurePac Arctic Medium

Oulu, Finland

The Oulu project is a PurePac Arctic and is designed to withstand extreme arctic weather, cold climate up to –40°C and a snow-load of one meter high. The biogas produced from sewage sludge and food industry waste streams is upgraded to Renewable Natural Gas trough Bright’s PurePac system.

This PurePac Arctic Medium purifies 399 SCFM of biogas (640 Nm³/hr raw biogas) to roughly 250 SCFM of RNG (400 Nm³/hr biomethane) which is used as Compressed Natural Gas (CNG).
