Abstract

In order to investigate the corrosion resistance of the materials used in the carbon capture unit of carbon dioxide capture，utilization and storage (CCUS) application，three kinds of metal materials，Q355，304L and 316L，were selected to carry out on-site corrosion hanging coupon test in eight typical locations of amine carbon capture unit and chimney in thermal power plant.The corrosion rates of the three materials at eight test points were calculated by weight loss method.The macroscopic and microscopic morphology after corrosion was observed，and the surface corrosion products of Q355 were analyzed by X-ray diffraction (XRD).Results showed that dew point corrosion and pitting corrosion of 304L could occur in chimney.The corrosion rates of 304L and 316L in the amine carbon capture unit were very low and no pitting corrosion occurred，which could be used as the material of the amine carbon capture device.In the process of amine carbon capture unit of Q355，the corrosiveness of liquid phase was higher than that of gas phase，and the corrosiveness of low temperature amine-rich solution was stronger than that of low temperature and high temperature amine-poor solution.The corrosion products in amine-rich solution were mainly FeO(OH)，and the corrosion products generated in amine-poor solution were mainly Fe3O4.

Key words： carbon dioxide capture; utilization and storage (CCUS); on-site hanging coupon; amine liquid; corrosion
