What are the O2 and N2 limits, and why do they matter?
sourced
Oxygen and nitrogen limits exist because air ingress - during air-dosing desulphurisation, or through membrane operation - dilutes methane and creates both a safety and a pipeline-quality problem. IS 16087 caps oxygen at 0.5%, so air dosing has to be metered precisely rather than set and forgotten.
