The generation of heat‐stable salts (HSSs) in alkanolamine solutions for CO2 capture processes, which is adapted for power plant technologies, exists irrespective of the class of amine solution used for the capture process. Their presence do not only trigger decrements in the CO2 absorption capacities of the solvents and contribute to further alkanolamine degradation, but also result in foaming and loss of solvents, which impacts system economics and threatens the environment. HSSs also promote the corrosiveness of the metallic structures of capture systems by lowering the pH and increasing the conductivity of the absorbent solutions. Overall, these effects substantially subvert the reliability and integrity of CO2 capture units. This survey affords sufficient background on the existence of HSSs by unraveling the flow process in a typical alkanolamine‐based CO2 capture unit with respect to their formation points and potential threats. Furthermore, the major HSSs removal and alkanolamine reclamation methodologies (electrodialysis, distillation, ion exchange, electromagnetic separation, and solvent extraction) were comprehensively explored. We believe that this review paper will benefit researchers across disciplines as we continue to explore new and complex solvent formulations to minimize the cost of CO2 capture while maximizing efficiency. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

Based on the CCUS project planned to run in a domestic oil field, the electrochemical corrosion at the bend of supercritical CO2 pipeline was studied by means of high-temperature and high-pressure reaction kettle hanging plate experiment, and the corrosion rate of X80 pipeline steel in unsaturated, saturated and supersaturated supercritical CO2 with water content was obtained. Then through COMSOL simulation of the corrosion rate of 90° bent pipe in the supercritical CO2 corrosion atmosphere, the maximum corrosion rate position of electrochemical corrosion generated under the action of flow accelerated corrosion (FAC) generated by supercritical CO2 fluid in the bent pipe was obtained, and corresponding anticorrosion Suggestions were put forward according to the research results.
