Biogas upgrading – FioGrade


Biogas is a naturally generated gaseous fuel, which mainly contains methane and carbon dioxide, together with water and other contaminants in traces. With proper treatment and purification, biogas can be transformed into biomethane, a sustainable substitute of natural gas, that can be injected into the existing gas grid.

Pietro Fiorentini’s complete and integrated biogas upgrading solution – FIOGrade allows to efficiently remove water and contaminants (like sulphur, ammonia and organic compounds), while separating out carbon dioxide thanks to membranes filtration. The entire process allows to recover around 99,5% of the methane contained in input biogas, producing a pure stream that can be directly injected into the gas grid.
