Effect of H2O Content on the Corrosion Behavior of X52 Steel in Supercritical CO2 Streams Containing O2, H2S, SO2 and NO2 Impurities

“…Carbon capture, utilization and storage (CCUS) is an important technique to combat climate change [1,2]. A large number of CCUS projects have been successfully applied worldwide, and the success of these projects relies heavily on the safety, reliability, and cost effectiveness of the CCUS process [3,4].…”

“…In CCUS projects, CO 2 pipeline, as the primary transport manner of CO 2 , is a key component in ensuring the safe and efficient transport of CO 2 from the capture site to its destination [5]. However, the inevitable presence of corrosive impurities such as H 2 O, O 2 , SO 2 , NO 2 and H 2 S in the supercritical CO 2 streams transported by pipelines can pose a serious threat to the service safety of carbon steel pipelines [2,[6][7][8][9][10][11][12][13].…”

“…However, the presence of impurity components in the captured gas is inevitable. For the particular system of supercritical CO 2 transportation pipelines, H 2 O in supercritical CO 2 streams usually exists in a dissolved state, and this form of H 2 O is largely unlikely to cause corrosion of pipeline steel [2,[15][16][17]. However, the presence of other impurity gases, such as O 2 , SO 2 , NO 2 and H 2 S, can significantly reduce the solubility of H 2 O in supercritical CO 2 and induce the precipitation of free aqueous phase [8,[17][18][19][20].…”

Microbial corrosion behavior of pipeline steels in simulation environment of natural gas transportation pipeline

“…[3][4][5] The occurrence of CO 2 corrosion on the inner surface of pipelines used for natural gas gathering and transportation is a prevalent form of acid corrosion. 6,7 Acid corrosion was rst reported in a Texas well in 1940, and since then, it has remained a persistent issue in various oil elds worldwide. 8,9 In the oil and gas industry, over 950 000 wells are characterized as acidic, constituting approximately one-third of all wells.…”
