Alphen-Chaam, Netherlands

Bright Biomethane installed a PurePac Medium biogas upgrading system at a farm in Alpen-Chaam, as part of the biogas digestion plant which has been set-in to generate biogas from manure.

By utilizing the membrane upgrading technology, the available biogas is upgraded to Renewable Natural Gas with the capacity of 186 SCFM (300 Nm3/hr), producing 91 million ft³ of RNG a year. The generated RNG, also known as green gas, is injected directly into the national gas grid and is sufficient for the average annual gas consumption of 1,500 Dutch households.

The installation is equipped with our unique heat-recovery system and an integrated grid entry unit, including THT injection.
