51318-11481-Impacts of Impurities SO2 and H2S on Corrosion of sc-CO2 Pipe Steels

This paper re-examines most public and in-house corrosion data on the effects of six typical impurities to advance the fundamental understanding of how pipeline steels corrode in sc-CO2 environments and identify knowledge gaps for further investigations.

Carbon dioxide (CO2) is the primary notorious greenhouse gas which is being increasingly emitted to our ecosystem as a result of various human activities. Carbon capture and storage (CCS) is the most promising technology available today for utilizing fossil fuels as reliable energy resources while significantly reducing CO2 emissions and protecting the climate. Pipeline transportation is recognized as the most cost-effective and relatively safe solution in the context of CCS, as it can transport large amounts of CO2 under predetermined and controlled conditions. Depending on CO2 sources and applied capture/separation technologies, however, the transported sc-CO2 stream always contains some aggressive impurities that could lead to extensive corrosion of pipe steels as well as cracking. The effects of impurities on corrosion are far from clear because of very limited field experience, scarce laboratory corrosion data and somewhat conflicting published results. This paper re-examines most public and in-house corrosion data on the effects of six typical impurities to advance the fundamental understanding of how pipeline steels corrode in sc-CO2 environments and identify knowledge gaps for further investigations. It is anticipated to advance the commercial deployment of CCS technology in a cost-effective manner.

Key words: CCS, corrosion, CO2, H2O, O2, H2S, SO2,acids, organics
