Biogas Upgrading Unit

We offer you turnkey solutions for biogas upgrading suited to your needs: Purification, injection, compression,liquefaction. Our experts support you every step of the way, from design phase to the delivery of the operational unit.

Biogas is upgraded by separating methane and carbon dioxide via an innovative process that uses proprietary polymeric hollow fiber membranes made by Air Liquide (Medal*). This efficient system generates high quality biomethane(CH4 content up to 99.5%).


Advanced Separations

We provide original membrane manufacturing technology offers leading performance for nitrogen generation, hydrogen recovery, carbon dioxide removal, biogas and natural gas treatment. MEDAL™ membrane modules and complete systems can be customized to meet your unique needs for air separation, nitrogen generation, carbon dioxide removal and hydrogen purification.
