Challenge
Biogas processing generates large quantities of CO₂, which is often released unused. To ensure its sustainable use, the CO₂ must be captured, compressed and made available for further processing.

Solution
Reciprocating compressors compress the captured CO₂ and enable its safe storage and reuse.

The systems used ensure reliable compression even during continuous operation and facilitate efficient integration into existing processes.

Implementation in France
At a biogas plant, the captured CO₂ is collected and compressed using a two-stage piston compressor. The compressor increases the pressure to up to 22 bar, thereby enabling the storage and further processing of the gas.

The CO₂ can then be used for various applications, for example in the drinks industry, in the production of e-fuels or in greenhouses.

Results

• Recovery and utilisation of CO₂ from biogas processes
• Reduction of emissions
• Reliable compression up to 22 bar
• Flexible reuse of the CO₂
