DID YOU KNOW?

Changes in waste can cause gas mix to vary, eg: gypsum (building waste) increases H2S, fresh waste produces more H2CO measurements are susceptible to cross gas effects from H2, H2S and VOCs, however, our H2 compensated CO cell and VOC filter can help obtain an accurate reading. CDM may demand data to show CH4 destruction.

LFG pumping trials with Automatic Flare Systems (AFS)

Application Landfill gas Customer Automatic Flare Systems (AFS) Requirement Managing director at AFS, Steve Willacy said, “We want continuous landfill gas monitoring and analysis and to use a data logger to record the results from the gas analyser.” Operation AFS uses its mobile flare skid for landfill gas pumping trials to analyse the quantity and...

Other applications

Gas flaring

Methane is a powerful greenhouse gas and should be destroyed before it enters the atmosphere. Flaring is a common solution for gas with CH4 10%-40%.

Landfill perimeter monitoring

Controlling potentially explosive and asphyxiant gases from escaping off site is important for meeting Health and Safety standards and protecting the local environment.
