Recovery of carbon dioxide from biogas production
Application | CO(low:2) recovery
Country | France
The gas produced in biogas plants is similar to natural gas, but contains undesirably high quantities of carbon dioxide (CO2) in its raw state, which must be separated after production. In many biogas plants, the CO2 is currently still released into the atmosphere. However, in order to counteract the global rise in CO2, the CO2 is increasingly being recovered - either directly from the biomass or via direct air capture from the ambient air - for further industrial utilisation.
For further utilisation, the CO2 captured during biogas upgrading is first compressed in order to store and liquefy it. A two-stage, oil-free piston compressor ensures that the captured CO2 is reliably compressed. This CO2 is then used for applications such as the carbonisation of beverages, the production of e-fuels or the supply of CO2 to greenhouses to promote growth.
