Bright Biomethane supplied a biogas upgrading installation for a project in Eppeville, France for upgrading biogas to Renewable Natural Gas using highly efficient membranes. This way, the separation of methane from biogas can reach an efficiency of more than 99.5% and render green gas suitable for injection in the national grid or compression to CNG.
The biogas upgrading system in this project has a capacity of 250 SCFM of biogas (400 Nm³/hr raw biogas) and upgrades the gas to 130 SCFM of RNG (210 Nm³/hr biomethane). The upgraded gas will be injected into the national gas grid. The upgrading system has been placed at an industrial digestion installation with a capacity of 35,000 tons per year. The input of the installation consists of manure, sludge and vegetables waste.
