BIOGAS UPGRADING TO RENEWABLE NATURAL GAS

Proven membrane technology achieving more than 97% operational availability. System is easily integrated with a biogas plant, provides optimal gas cleaning, a robust design, an advanced patented control system and the assurance of 24/7 service support.

Having constructed the world’s first commercial plant for upgrading biogas using a 3-stage membrane system, Bright Biomethane successfully uses this proven design in its systems operating today.

The advanced design and patented control system makes it possible to inject specification compliant RNG to grid within a few minutes of start-up. Other technologies can take much longer to start-up with resultant methane losses and operational inconvenience. Bright Biomethane plant operators have the option to stop and start the facility at their convenience with minimal methane loss and no wasted energy consumption.

99.5% methane recovery, more than any other system. The lowest electricity consumption (0,22 kWh/Nm³ biogas). No heat required for the biogas upgrading process. Heat recovery (> 0,25 kWt/Nm³ biogas) covering the main energy consumption of the biogas facility. Competitive price level.

A Bright Biomethane CO₂ recovery unit can also be integrated with the standard 3 or 2 stage membrane upgrading systems. The high separation efficiency of the membranes means that the energy consumption of CO₂ liquification is much lower than conventional systems.

No water or chemicals are needed in the Bright Biomethane process which means that there are no disposal problems, such as acid water or chemicals that can be an unforeseen cost with other technologies.

Bright Biomethane is experienced in managing biogas produced from most forms of biomass feedstock, including municipal sludges and wastes. Based on this experience, reliable biogas pre-treatment solutions can be offered to ensure the correct biogas specification is achieved before upgrading.
