SEPURAN® Green G5X 11” biogas separation membranes 

Evonik’s SEPURAN® Green membranes are designed for upgrading biogas to high-quality renewable natural gas (also known as RNG or biomethane), in large landfill, agricultural, organic waste, and wastewater treatment projects. 

Along with improved cost-efficiency, the extraordinarily high capacity of this market-leading membrane enables upgrading projects to see greater gains in overall sustainability and defossilization. 

• improved cost-efficiency due to extremely high capacity based on volume and weight
• high selectivity, with RNG/biomethane purity and yield levels adjustable according to your requirements (e.g. up to less than 50 ppm CO2 or up to 99.8% CH4 yield)
• compact, pressure certified membrane systems, requiring fewer piping connections and welding time
• low energy consumption, with only ~0.2kWh/Nm³ for high purity and yield systems – or lower for less demanding configurations
• proven service lifetime of biogas membrane greater than 10 years
• produced with 100% renewable energy

Evonik’s SEPURAN® Green membranes for upgrading biogas have been on the market since 2011. From that moment, the foundation was laid for future achievements and breakthroughs in membrane technology. Today, Evonik’s membranes are in service at over 1400 RNG system installations worldwide.
