Corrosion failure of compressed-natural-gas transmission lines. Anon. JPT, May 1998, 50(5), 85. (Synopsis SPE paper 39536).

Attention is drawn to the internal corrosion of pipelines carrying lift gas for, and production from, gas-lifted wells, heavy localized pitting being a distinguishing feature of a system attacked by CO2. The influencing factors are discussed, test results are reported, and a failure analysis is examined. Corrosion control is described and it is concluded that injection of a film-forming amine inhibitor is an effective method of corrosion control for a compressed-gas transmission line. The amine inhibitor being sprayed into the transmission line as a fine mist in the same direction as the gas flow.
