Purging H2S rich environment with Nitrogen causes the Nitrogen gas to turn sour.
Natural gas & Nitrogen are required to be treated for noxious gasses such as H2S,
SO2 or other lethal gasses before they can be released or distributed.
Our portable gas scrubbers can absorb the H2S, SO2 (sour gasses) and other noxious gasses from Nitrogen or Natural gas.
After this process, Nitrogen will be safe to vent to atmosphere and the Natural gas will be ready for processing / transportation.
