Other than the need to meet the regulatory requirements for gas quality; there are many reasons why oxygen is undesirable in natural gas:
|Oxygen measurement to protect personnel and equipment from explosive hazard due to methane resulting from decomposition of bio-ponds.
|0 to 5% O2
|N2 or CO2
|Vacuum extraction techniques create the possibility of contamination by air that exceed contractual limits of O2. Monitoing the oxygen ensures early warning of possible breaches.
|0-100 ppm O2
|CH4, CO2, H2S
H2S Sample System required
