Biogas Upgrading

The CRA Biogas Upgrading System is capable of achieving over¿¿¿ 98% methane concentration. This is possible with the help of our advanced multi stage membrane process.

The process begins with drying and scrubbing the biogas. Next, the gas is compressed to allow for proper functioning of the separation membranes. This compressed air is passed through multiple sets of membranes separating the gas into <0.5% carbon dioxide and >98% methane concentrations.
