AirScience Biogas and Landfill Gas Flares

—AirScience Technologies offers technologies for the remedial of unwanted emissions of biogas and landfill gas.

 

Biogas is a mixture of methane (CH4) and carbon dioxide (CO2) with impurities such as water vapour, hydrocarbons, siloxanes, hydrogen sulfide (H2S), and organic sulfur. Biogas is toxic, odorous, explosive and most of all a very potent greenhouse gas and as such must not be vented to atmosphere.

 

One major source of biogas is municipal solid waste landfills, as these landfills receive a large amount of organic waste, substantial amounts of biogas (land fill gas) is generated by the biological degradation of this mass of organic waste. Most jurisdictions have mandated the capture of landfill gas at the source and the destruction of that landfill gas through enclosed flame flares.

 

As biogas is more and more valorized as a renewable energy source, the destruction of biogas through enclosed flame flares is only required in case of biogas production in excess of the capacity of the biogas purification system and or during the maintenance of the biogas purification or utilization system.

 

Enclosed flame flares when properly sized and designed provide full combustion of the combustible gases in the biogas. With a 1000°C combustion temperature and minimum retention time of 0.3 seconds, enclosed flame flare provide the best available control technology (BACT), and should be used for all biogas venting applications.

 

AirScience AST-EFF standard enclosed flame flares have capacity of 150 Nm3/h to 3,000 Nm3/h, larger sizes are available as engineered units using the same design as the standard AirScience enclosed flame flares.

AirScience Technologies was formed
in 1993 from the merger of two companies, Canadian and American. After fifteen years of designing and building air pollution control systems for various industries, the company has refocused its activities on biogas purification and biogas flares.
