Corrosion is an essential operational factor to characterize for future demonstration and commercial carbon capture plants. In this paper, three approaches have been used to investigate corrosion in CO₂ capture pilot plants: corrosion coupons, on-line monitoring and pilot plant inspection. These tests were realized in two pilot plants: Esbjerg, Dong Energy and Maasvlakte, TNO. Consistent results were obtained. In general, carbon steel and austenitic stainless steel behave well in most of the zones. Several more critical zones have been identified: stripper sump, high temperature lean solvent pipe, reboiler and reclaimer. Some corrosion mechanisms such as flow induced degradation, corrosion due to CO₂ or the corrosive effect of the solvent degradation have been evidenced.
