We are there for you for the complete life cycle of your system, from design to commissioning to operation and maintenance, with global service hubs and dedicated technical support.
Conquer energy market volatility by reducing reliance on fossil based fuels with renewable fuel, biomethane.
New revenue streams
Sell biomethane to the national grid, use bio-CNG or bio-LNG as a transport fuel and use bio-CO2 for industrial applications such as fresh product packaging.
If you have an emissions target to reach, talk to Pentair. Become a circular business through biogas upgrading.
The heart of the system is the membrane separation unit. The membrane separates the two major gas components: CH4 and CO2. The separation is accomplished through the pressure difference over the membrane surface.
The high-pressure biogas is fed into the membrane, and the CO2 passes through the membrane surface to the permeate, the low-pressure side, much faster than CH4.
The membranes are pressure-driven, so the higher the pressure, the more CO2 will pass through the membrane surface. The discharge from the membrane (the retentate) contains mainly CH4, as the CO2 has been pushed through the membrane surface. The CO2 rich gas will leave the membrane on the low-pressure side of the membrane (permeate).
