“…Experts have identified the following as the leading factors influencing metal corrosion in alkanoloamine units 54–56 : temperature, solution velocity, amine loading, CO 2 and O 2 loading, concentration and type of alkanoloamine solution, contaminants in alkanoloamine solutions including HSS. Also, several other researchers have confirmed the influence of temperature in power plant‐related corrosion problems in addition to material type and flue gas composition (leading to HSS generation) 57–60 . In addition to reducing the CO 2 absorption capacity of alkanolamines, HSSs accumulation has also been proven to significantly increase the corrosiveness of the absorbing solutions 61–63 .…”

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.
