The conversion from biogas to biomethane occurs through a purification process (dehydration, desulphurisation, removal of gaseous ammonia, NH3, mercaptans, dust) and upgrading (removal of carbon dioxide, CO2).
- Biogas cleaning: removal of water, H2S and traces of unwanted contaminants (dust, siloxanes, ammonia…);
- Upgrading: removal of CO2 to reach the quality standards required by the gas network and uses as biofuel;
- Biomethane: refined biogas for injection into the grid or use as a biofuel.
