Biogas & landfill gas upgrading

Bright Renewables is a one-stop-shop for biogas upgrading, offering systems for the upgrading of biogas and landfill gas. Specifically designed for biogas, our PurePac upgraders utilize membrane technology to ensure high-quality purification. For landfill gas, we employ a dual approach, combining membrane technology with pressure swing adsorption (PSA) technology, to effectively remove impurities, enhance the gas quality, and increase the methane content. This in-house dual-technology ensures the optimal purification for both biogas and landfill gas, catering to a wide range of purification needs.

The PurePac

An overview of our PurePac biogas upgrader with its distinguished technologies for the upgrading of biogas and landfill gas. The image below is an illustrative representation.

Patented control system

Our biogas upgraders excel due to a smart operating system, enabling biomethane-to-grid in minutes with high up-time. It adjusts the Wobbe-index and methane range swiftly, maintains stable gas quality, and minimizes maintenance through continuous monitoring.
Gas treatment

Membrane separation technology

At the core of our biogas upgrading systems lies an highly-efficient 3-stage membrane technology. Ensuring efficient biomethane / RNG production.
Membrane technology

Biogas compressor

In our upgrader, the biogas first enters the pre-treatment system where moisture and contaminations, such as H2S, are filtered out. After that, the gas is compressed in the compressor to reach the required pressure before entering the membrane system.
Gas treatment

Gas treatment

To reach high-quality biomethane / RNG production, Bright incorporates raw biogas treatment in the biogas upgrading technology to ensure the removal of impurities in the biogas stream.

PurePac biogas upgrader

The PurePac is our well-proven biogas upgrader to purify biogas and landfill gas. Biogas upgrading is a very attractive alternative compared to using a combined heat and power (CHP) system that generates electricity and heat. Our range of PurePacs for biogas upgrading is an essential add-on for all types of new and existing biogas plants in any industry. Additionally, our CO2 liquefaction system can be added for the production of liquid food-grade bioCO2 further boosting the efficiency of the biogas upgrading process and improving the carbon intensity (CI) score.

UltraLow-E: Lowest electrical consumption

In addition to our standardized PurePac, we offer the UltraLow-E design of our proven biogas upgrader system. This system in combination with our CO2 liquefier is able to reach the lowest electrical consumption of as low as 0.17 kWh/Nm3 of raw biogas. Aside from higher sustainability, this results in lower electricity consumption, and lower operating costs, and can qualify for (higher) subsidies and incentives.

Key advantages

High methane yield of ≥99.5%
Lowest energy consumption
Patented control system
Low operational & maintenance costs
Maximum heat recovery

Patented smart control system

Our biogas upgrading systems wouldn’t work as excellent without its smart operating system that ensures biomethane-to-grid within a few minutes after start-up. It also ensures the highest up-time, i.e., the Wobbe-index and methane range can be quickly adjusted without disconnecting from the grid. Continuous monitoring and actively adjusting the flow and quality of the biomethane ensures a stable quality of the product gas and low maintenance. If in need of maintenance, our in-house service team provides 24/7 support for all our technologies, ensuring prompt and efficient assistance.

Comprehensive service & maintenance

Our comprehensive expertise in biogas upgrading technology is enhanced by in-depth in-house service and maintenance across all our technologies, ensuring high operational availability and continuous production processes. Through predictive maintenance, we use real-time sensor data to prevent equipment failure and downtime. We proactively identify issues to minimize downtime and ensure high plant availability.

Large-scale biomethane production

Biomethane capacity
0 million Nm3 / year
CO2 savings
0 metric tons / year

In Lommel, Belgium, this renewable energy facility produces biogas from organic residues. The biogas is upgraded to biomethane with a PurePac Grand and injected it into the gas grid. Nearby companies supply these residues, including potato peels, to the biogas plant to produce biogas which is purified to biomethane using membrane technology. With the addition of our biogas upgrading system, the client aspires to the effective realization of a fully interconnected renewable energy plant, uniting all available production technologies on one site. Bright has extensive experience with large-scale biogas upgrading projects.
