Bright Renewables First to Implement Evonik’s 11” Membranes in Biogas Upgrading Tech
PurePac Supra
In line with these green membranes, which are produced with 100% renewable energy, Bright developed the PurePac Supra. With a capacity coverage starting at flows as small as 2,500 Nm3/hr (1,471 SCFM) of biogas it is the largest capacity in the company’s biogas upgrading line. This modular upgrader, that purifies biogas to biomethane or renewable natural gas (RNG) with a high methane content, is scalable to much higher capacities through multiplying the setup while maintaining a methane recovery of >99.5%.
The 11” system is packed with ultra-thin polymer membranes to separate methane and carbon dioxide. Its design allows for a more compact setup, requiring fewer membranes while delivering higher performance in a single unit. This results in exceptionally high capacity relative to volume and weight. As a result, the 11” size has become the new standard for large-scale biogas upgrading projects, replacing the 6” membranes – which are still integrated in the other capacity PurePac biogas upgraders.
“We stay agile in adapting to industry trends and adapt through working closely with customers and their wishes, project developers, in-house engineers and R&D teams, and external suppliers. Our strong, long-term partnership with Evonik enables us to drive innovation, and we’re proud to be trusted by many worldwide. These membranes are already in use or soon will be, starting in the Netherlands and the USA, and have a combined upgrading capacity of circa 20,000 Nm3/hr of biogas.”, said Mark Smit, business unit director of Bright Renewables, headquartered in the Netherlands.

Large-scale output
Larger-scale biogas upgrading projects are gaining momentum, and Bright is seeing a growing demand for these high-capacity projects. Beyond their economic potential, membrane biogas upgrading technology plays a crucial role in expanding the adoption of renewable energy across the globe.
“Bright Renewables is constantly evolving, just as Evonik continues to push the boundaries of innovation. Both companies share a commitment to advancing high technology products, driving efficiency, and setting new industry standards.”, said Jennifer Doerper, Director SEPURAN® Green at Evonik, with headquarters in Germany and membrane production facilities in Austria.
