Biogas Compressor: How It Works and Applications

Biogas compressors pressurise gas from anaerobic digestion for power generation, upgrading or injection. The gas is wet and corrosive, so the compressor design must handle those challenges.

How It Works

  • Compresses biogas produced from organic waste digestion.
  • Handles methane, CO2 and trace contaminants.
  • Often uses special materials to resist corrosion.

Applications

  • Feeding gas engines for electricity generation.
  • Biogas upgrading to biomethane.
  • Flare systems and gas storage.

Selection Factors

  • Gas composition, moisture and hydrogen sulphide content.
  • Required flow and discharge pressure.
  • Safety features for explosive gas handling.

Why does biogas need special compressors?

The gas contains moisture and corrosive trace compounds that require resistant materials and proper gas treatment.
