Odor Control + Get Alerts

Biogas is corrosive and can be dangerous if not handled properly. Geomembrane Technologies Inc. (GTI) offers control systems to safely operate its biogas collection covers. The system delivers collected biogas into a pipeline for renewable energy conversion or disposal while monitoring and protecting the cover.

GTI’s biogas control systems are designed to:

  • Safely deliver biogas to be converted into green energy
  • Protect the cover from damages
  • Control sediment and moisture in the gas
  • Withstand corrosive gases
  • Allow real-time remote monitoring
  • Alert operators of unsafe operating conditions

The control system regulates the withdrawal of biogas from underneath the cover. The system maintains a consistent vacuum by removing biogas at the same rate as it is generated. The cover is drawn to the water surface, helping protect it from potential damages. Advanced control options for biogas storage can be incorporated to optimize biogas utilization in engines or boilers.

The base system includes sufficient equipment, instrumentation and programming to safely regulate the flow of biogas and flare disposal. The system can deliver the biogas for use in most low-pressure applications such as boilers. Special considerations are necessary to use the biogas at high pressures.

Biogas pipelines, valves and other equipment are made with corrosion-resistant materials and critical parts are typically stainless steel. Moisture traps and safety valves are included. In the event of power failure or blower maintenance, emergency vent stacks are provided to allow biogas to be dispersed into the atmosphere.

A programmable logic controller is used to display and trend operational data and provide automatic control of the system. The PLC provides a local operator interface and offers outputs for remote monitoring. Alarms are programmed to notify operators of issues in real-time.

With over 30 years of experience delivering solutions for demanding water and wastewater applications, GTI has grown to become a global leader in biogas collection. The company has supplied and installed complete mechanical, electrical and control packages on cover projects all around the world.
