The Netherlands-headed Bright Renewables, a high-tech supplier of renewable gas systems, has announced that it 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, maintenance and increase assembly efficiency.

In line with these green membranes, which are produced with 100 percent renewable energy, Bright Renewables 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.

Modular and scalable

The PurePac Supra is a modular biogas upgrader, which purifies biogas to biomethane aka renewable natural gas (RNG) with a high methane content.

It is scalable to much higher capacities by multiplying the setup while maintaining a methane recovery of >99.5 percent.

The 11” system is packed with ultra-thin polymer membranes to separate methane (CH4) from carbon dioxide (CO2) contained in the raw biogas.

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 into 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 United States, and have a combined upgrading capacity of circa 20,000 Nm3/hr of biogas, said Mark Smit, Managing Director of Bright Renewables.

Large-scale output

Larger-scale biogas upgrading projects are gaining momentum, and Bright Renewables 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 of SEPURAN Green at Evonik.
