Nitrogen can also be used to purge the pipeline after pigging has been completed. In this case, the dry gas is run through the line without the pig to dry up any remaining water in the pipeline.

Nitrogen discharge into the 48-in. pipeline occurred immediately before its gas fill, resulting in a 120-km nitrogen batch at atmospheric pressure in the 48-in. line. Air-nitrogen slug ...

The maintenance and integrity of pipeline networks are critical to global energy infrastructure. Pipeline inspection and pigging operations employ specialised devices – commonly known as PIGs ...
