Biogas Delivery System and OEF150 Flare

The by-product from the processing plant and waste water, are directed to Covered Anaerobic Ponds (CALs) and from here biogas is captured and used as an alternative fuel source to co-fire the boiler to produce steam for the plant.

ABM worked in close collaboration with the project engineers, to design a system of pipework which would effectively deliver the biogas to the boiler. Key elements of the projects produced by ABM:

• Biogas delivery system including a PDA blower, methane analysers, pressure transmitters, CAL control valves, and water seals to control CAL pressure.
• ABM specialist OEF 150 flare with high reliability, high turn down, fast response and good destructive efficiency.
• The boiler which was modified to accept biogas, is now co-firing using the biogas and annual energy costs are expected to fall significantly
