Portable and fixed gas analysers for landfill gas field management - Waste and Recycling - Landfill

Careful management of the many boreholes across a landfill gas field can optimise the gas yield and therefore the power generated from the gas.

Gas source / feedstock

  • General landfill waste

Typical gas mix

  • CH4 60%
  • CO2 40%
  • O2 0% (unless gas lines breached)
  • CO (>100ppm may indicate an underground fire) 0-2000ppm
  • Gas flow 0-5,000m3/h
  • H2S 0-3%
  • H2 0-30,000ppm

Where does it occur?

  • Worldwide

DID YOU KNOW?

Changes in waste can cause gas mix to vary, eg: gypsum (building waste) increases H2S, fresh waste produces more H2. CO 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.
