The Puregas CA process recovers over 99.9% of the biomethane present in the raw biogas by separating the CO2 from the biogas through a process of chemical absorption. The selective organic solvents used in this process are so efficient that the product gas can contain over 99% biomethane. The biomethane or Renewable Natural Gas can be directly injected in to the gas grid, compressed to produce bioCNG or liquefied for bioLNG. It’s also possible to capture the CO2 from the plant and use this for commercial purposes. All plants are fully factory tested and third party inspected prior to shipment.
At More Biogas, most of the bioCNG is fed into composite trailers, each capable of storing 5,000Nm3 of biomethane, which are then transported to the local municipality bus depot to fuel their fleet of CNG busses.
The remainder of the bioCNG is stored locally and sold to the general public to fuel their Natural Gas Vehicles (NGV).
The plant produces enough bioCNG to displace over 3 million litres of diesel each year.
Surely we need More of this?
