Bright Renewables, high-tech supplier of renewable gas systems, is the first to integrate Evonik’s SEPURAN® Green G5X 11” in its membrane separation-based biogas upgrading technology. These newly launched membranes feature the highest capacity of its kind on the market and are designed to decrease costs and maintenance and increase assembly efficiency.
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, Managing Director of Bright Renewables, headquartered in the Netherlands.
