Oxygen can cause corrosion in RNG pipelines, so it is tightly restricted. Most RNG projects must meet a certain O2 spec, usually much lower than what is in raw biogas. Regarding oxygen reduction / removal methods, I can’t really speak on this topic but it would be needed and I believe there are technologies out there for deoxygenation.

Depends on the natural gas pipeline company, but max oxygen content seems to be around .0.2% to 0.4% by volume. RNG seems to have stricter limits, <= 1.0% by volume, even some trends toward Ultra-trace oxygen limits down to <= 0.005% (50ppm). The limits are based around minimizing risk of corrosion.

HI Natalia and great question on why O2 measurement is important in Biogas/RNG industry. There are 2 critical O2 measurement challenges that the Barben OXYvisor solves. First challenge; methanogenic bacteria that is used in the digestor can’t survive in the presence of O2, therefore monitoring the levels is crucial since any increase in O2…
