含杂质超临界CO 2 输送管线腐蚀的研究进展
摘要
A range of impurities may exist in supercritical CO2 stream of transmission pipelines for carbon capture and storage (CCS) process, which are the potential corrosive factors to induce opera- tional risks of the supercritical CO2 transmission pipeline. The impurities induced inner side corro- sion of supercritical CO2 pipelines may become the bottleneck restricting the development and ap- plication of CCS. This paper reviews the recent research progress on the corrosion behavior of pipe- lines for supercritical CO2 transmission. The potential corrosion risks and the impact factors on cor- rosion are analyzed. The influence of impurities on the phase behavior, water chemistry characteris- tics, corrosion scales and the corrosion mechanism of transmission pipelines is also discussed. The shortcomings in the present investigations and the key scientific problems for further research are
