Research Progress on Anti-corrosion Technologies for Supercritical CO2 Pipeline

Carbon capture and storage technology (CCS) is one of the important means for carbon emission reduction. There exist serious corrosion issues for pipelines related with the transportation and application of supercritical CO₂. Therefore, it is of urgent need to carry out study on the corrosion behavior of pipeline in the relevant environments of supercritical CO₂ and thus to develop applicable anti-corrosion technologies. In this paper, the mechanism of supercritical CO₂ induced corrosion of pipelines and the related anti-corrosion methods are reviewed. The different anti-corrosion technologies such as corrosion-resistant materials, inner coating and corrosion inhibitor are discussed emphasically. The advantages and disadvantages of different technologies are compared and analyzed. The limitations of current research on supercritical CO₂ pipelines are further pointed out. Finally, it is also forecasted on the future research directions of supercritical CO₂ issues.
