Challenge
In order to inject biogas into the natural gas network, the methane content must be raised to natural gas levels and the gas compressed to the required network pressure. Reliable pressure boosting and stable operation are crucial in this process.

Solution
Reciprocating compressors compress the treated biogas and ensure the necessary pressure adjustment.

The systems used enable safe and continuous injection into the gas network and are designed for continuous operation.

Implementation in Germany
A piston compressor from the TRE 400 series is used in a biogas processing plant. The compressor increases the pressure of the processed biogas from 10 bar to up to 26 bar, thereby enabling feed-in to the natural gas grid.

The plant has a compact design and ensures reliable integration into the overall process.

Results

• Reliable injection of biomethane into the natural gas network
• Stable pressure increase up to 26 bar
• Safe and continuous plant operation
• Efficient use of renewable energy
