The process consists in separating methane from the other compounds (carbon dioxide, water, oxygen…). It is based on the use of high performance membranes which make it possible to reach a purification rate of >99 % and a quality of biomethane that complies with the standards required for injection into the natural gas network.

Biomethane is odorised using the by-pass method, by running the gas through a tank containing a liquid odorant. Ensured by the difference in pressure both upstream and downstream of the apparatus, the biomethane flow rate does not necessitate a pump and therefore there is no energy cost involved. The final concentration of THT injected in the biomethane is regulated continuously by an automated system.
