Evonik introduces market-leading high capacity biogas membrane  

  • SEPURAN® Green G5X 11” features highest capacity of its kind on the market 
  • Ideal for upgrading projects geared towards sustainability and defossilization 
  • Higher capacity membranes designed to increase cost-efficiency for customers 

Marl, Germany. Evonik has unveiled its latest biogas membrane, the SEPURAN® Green G5X 11”, featuring the highest capacity of its kind currently on the market. Specifically designed for upgrading biogas to renewable natural gas (RNG) in large landfill, agricultural, organic waste, and wastewater treatment projects, the membrane is specifically engineered for maximizing sustainability and efficiency gains in biogas upgrading projects. 

“The launch of this product addresses the growing demand for our membranes among large-volume biogas upgrading projects in landfills and other large RNG projects,” says Jennifer Doerper, global director of biogas membranes at Evonik. “The market-leading capacity of our SEPURAN® Green G5X 11” makes it the ideal choice for customers looking to boost their cost efficiency.”

The SEPURAN® Green G5X 11” is designed with double the capacity of the SEPURAN® Green G5X 6”L, and is ideal for largeflow projects among landfills. Used in Evonik’s 3-stage configurations, which are patented in the US, it excels in maximizing methane recovery rates and enabling high onstream times.  

Additionally, Evonik’s SEPURAN® Green G5X 11” offers more compact systems, less piping connections and welding time, and is easy to operate due to its ability for precise monitoring.    

Scheduled to enter production later this year, the new SEPURAN® Green G5X 11” will be on display at the Evonik booth during the RNG WORKS trade show from September 10 to 12 in Nashville, Tennessee, in the US. At the event, Evonik’s membrane technology experts will be on hand to discuss custom biogas solutions. 

Evonik launched its first membrane product—SEPURAN® Green, for efficient upgrading of biogas—on the market in 2011, laying the foundations for future business in membranes. This was followed by further membrane products for nitrogen, helium, hydrogen, natural gas, and nanofiltration applications. Today, Evonik’s membranes are in service in 200 biogas installations in North America, and more than 1000 worldwide.
