An overview on the corrosion mechanisms and inhibition techniques for amine-based post-combustion carbon capture process

Among the available carbon capture technologies, post-combustion carbon capture based on amine has become a well-proven and efficient means of reducing greenhouse gas emissions on an industrial scale to address global climate issues. However, corrosive behavior inevitably occurs during the trapping process, which could lead to operational problems, shorten the life of the equipment, compromise the production of products, affect economic efficiency, or even threaten human health. In order to present a comprehensive overview of corrosion behavior in the process of CO₂ absorption into amines, this paper covers the corrosion mechanisms, measurement techniques, and influencing factors. In addition, topics also cover in detail the corrosion mitigation measures of types of corrosion inhibitors and corrosion mitigation mechanisms. All exhibited information could provide a comprehensive knowledge of corrosion and corrosion inhibition in the carbon capture process and gave a pavement to facilitate further research in solving corrosion issues.
