Valopur
Biomethane / RNG production using membrane technology
After the digester and pretreatment process, the compressed gas undergoes further filtration within VALOPUR.
This is a compact unit housed within a pre-equipped container and composed of three stages of membranes which separate CO2 from CH4.
This system allows to produce Biomethane / RNG compliant to network specifications, with upgrading efficiency up to 99.5%. PRODEVAL selects the most suitable membranes available on the market to meet the specific needs of our customers. The three stages membrane system deliver operational flexibility, ensure optimal upgrading efficiency across the unit’s operating range.
Once purified, Biomethane / RNG is channeled towards the grid injection station which is connected to the natural gas network.
