Biogas Upgrading

Biogas upgrading technology converts raw biogas into biomethane using membrane separation, delivering >99.5% methane recovery. The gas meets renewable natural gas (RNG) standards for high-value use.

Virtual pipeline (bio-CNG) 

Virtual pipeline technology compresses biomethane into bio-CNG for easy road transport from remote production sites. It enables off-grid projects to access gas grid entry points.

CO₂ Recovery & Liquefaction 

CO₂ recovery and liquefaction system captures CO₂ from biogas upgrading and converts it into high-purity liquid bio-CO₂. It enables additional revenue generation while reducing carbon emissions.

Alkaline-process Biological Desulfurization System

Biological desulfurization system removes H₂S from biogas using an alkaline biological process, ensuring stable gas quality. It protects downstream equipment and enables reliable biogas utilization.

Natural Gas Liquefaction System  

Natural gas liquefaction system converts biomethane into bio-LNG or liquid biomethane, enabling efficient storage and long-distance transport. It enhances energy utilization while supporting sustainable fuel production.

Containerized CO₂ Purification System 

CO₂ purification system captures CO₂ from combustion flue gas and converts it into gaseous or liquid CO₂. The modular design enables flexible deployment for carbon utilization and emission reduction.
