The corrosive behaviour of loaded amine solvents was evaluated under stripper operating conditions, for post-combustion carbon capture, to determine the feasibility of using carbon steel in plant construction. In addition to monoethanolamine, three alternative amine solvents: methyldiethanolamine (MDEA), 2-amino-2-methyl-1-propanol (AMP), 1-(2-aminoethyl)piperazine (AEPZ), and the common additive K 2 CO 3 were studied when in contact with carbon steel (C1018) over a 28-day period. Corrosive behaviour was evaluated using carbon steel coupons: gravimetric method for weight change, surface imaging (SEM) and analytical techniques (EDX and XRD), and Fe ion concentration in solution (ICP-OES). The results demonstrated that MDEA and AMP as well as K 2 CO 3 develop a significant siderite (FeCO 3 ) layer on the carbon steel surface. The presence of this layer is attributed to the preferred reaction pathway with CO 2 for tertiary and sterically hindered amines. The FeCO 3 layer formed in the case of MDEA provides superior protection from continued corrosion of the carbon steel. By contrast, MEA and AEPZ show significant corrosion to the carbon steel surface. In conclusion, MDEA, AMP, and K 2 CO 3 can preferentially produce sufficient surface FeCO 3 layers to reduce corrosion levels in carbon steels for use under stripper conditions in postcombustion carbon capture plants.

“…To lower the energy cost, many new absorbents have been developed in recent years [6,7], e.g., MEA promoted MDEA (N-methyldiethanolamine) aqueous solution. MDEA has the advantages of high resistance to thermal and chemical degradation, and low corrosivity [8]. However, the absorption of CO 2 in MDEA aqueous solution is quite slow.…”

“…As oil and gas emerge from geological formations they are often accompanied by water and varying amount of 'acid gases' such as carbon dioxide (CO 2 ) and hydrogen sulfide (H 2 S). Several investigations [7][8][9][10][11][12][13][14][15][16][17][18][19] have been reported to study the erosion-corrosion phenomena involved.…”

Hydro-transportation is an economic and flexible way to transport natural resources such as oil and gas from excavation to the extraction plants, refineries, and consumer-ready products to markets. However, interaction between solid particles, corrosive fluid, and target material often results in significant mutual reinforcement due to the combined action of erosion and corrosion. In this study, erosion-corrosion behavior of API pipeline steel has been assessed in 2 g l -1 NaCl solution purged with CO 2 as the corrosive media and aluminum oxide as the erodent. Four different particle velocities (36, 47, 63, and 81 m s -1 ) were employed, while the angle of incidence was kept constant at 90°. The synergism between erosion and corrosion has been studied by means of a newly designed test approach to mitigate the limitations of the in situ method and to identify the effect of erosion on corrosion and vice versa. The corrosion process was monitored using potentiodynamic polarization and weight loss measurements. Total material loss rate and the components of erosion, corrosion, and their synergistic interactions have been determined. Scanning electron microscopy examination and experimental results show that there is an immense correlation between erosion and corrosion. Significant synergism was observed due to the interaction of different erosion and corrosion mechanisms.
