摘要：

Carbon capture, utilization and storage (CCUS)is a key method to achieve low carbon utilization and carbon neutrality of fossil energy. With the continuous development of CCUS technology, the internal corrosion problem of supercritical carbon dioxide (CO2)transportation pipeline has gradually become one of the key pain points affecting the safe operation of CO2 transportation pipeline. The corrosion behavior and mechanism of pipeline steel in supercritical CO2 medium are quite different from that of traditional CO2 corrosion happened in oil & gas environment, which is a bran-new corrosion problem research system. This paper reviews the influence of impurities, temperature, pressure and flow rate on the CO2 internal corrosion behavior of typical pipeline steels under supercritical conditions and the main incentive of supercritical CO2 pipeline corrosion caused by aqueous medium is taken as a clue. The water content is detailly discussed and compared especially. Generally, the future focus on the supercritical CO2 corrosion issues is prospected. The challenges that still exist in the current supercritical CO2 pipeline transportation process are analyzed as well. The conclusions are helpful to guide the design optimization of future carbon pipeline engineering and develop corresponding corrosion control methods. © 2024 Cailiao Daobaoshe/ Materials Review.
