High-Pressure CO₂ Removal for Methane Enrichment
The CO₂ water scrubber is one of the most widely used technologies for biogas upgrading. It removes carbon dioxide from biogas, increasing methane concentration for Bio-CNG production.
HOW IT WORKS
Compressed biogas is passed through a water-filled column where CO₂ dissolves in water due to its higher solubility, while methane remains in the gas phase.
The purified gas is then collected with higher methane concentration.
BENEFITS
- High methane recovery
- No chemical consumption
- Stable and reliable operatio
- Low operating cost
- Suitable for medium to large plants
