Our solution to upgrade biogas is based on chemical absorption. The process is compact and can produce biogas with very high methane concentrations (Wobbe index above 46.5 MJ/Nm3). Additionally, given the nature of the solvent used (specifically for CO2 removal), methane losses are negligible and lower than 0.04%.
- The lowest methane slip among biogas upgrading technologies (< 0.04%)
- Compact and simple to operate process
- High CO2 removal rates
- Possibility to produce food-grade CO2
