“…According to Lang andMason (1958), Treseder (1984), and Kohl and Riesenfeld (1985), the dissolved CO 2 is a primary corroding agent in alkanolamine gas-treating plants. Several iron corrosion mechanisms in aqueous CO 2 solutions have also been reported.…”

Corrosion and corrosion inhibition in a sterically hindered amine, 2-amino-2-methyl-1-propanol (AMP), were investigated by static weight loss tests. The corrosion data were compared with those of monoethanolamine (MEA), a conventional alkanolamine, which was simultaneously tested under the same conditions. The results indicated that the AMP system was generally less corrosive to carbon steel than the MEA system, but corrosion control is still necessary. Sodium metavanadate (NaVO3) and sodium sulfite (Na2SO3) were proven to be effective corrosion inhibitors, with more than 90% protection efficiency.

“…Most people thought the major parameters contributing to the corrosion process are dissolved carbon dioxide (CO 2 ), dissolved oxygen (O 2 ), alkanolamines, degradation products, temperature, and solution turbulence. Lang and Mason (1958), Treseder (1984), and Kohl and Riesenfeld (1985) reported that the dissolved CO 2 was a primary corroding agent in alkanolamine gas treatment plants. Several iron corrosion mechanisms in aqueous CO 2 solutions have also been reported.…”

“…Several iron corrosion mechanisms in aqueous CO 2 solutions have also been reported. One example is the reaction scheme of iron dissolution in bicarbonate solution proposed by Burstein and Davies (1980 Lang and Mason (1958), Kohl andRiesenfeld (1985), andDuPart et al (1993) reported that alkanolamines themselves were not corrosive to carbon steel, regardless of temperature. They did indirectly influence corrosion rate by absorbing CO 2 .…”

CO2 Capture from Flue Gas by Phase Transitional Absorption

CO 2 is accumulated in CO 2 rich phase. After separating the two phases, CO 2 rich phase is forward to regeneration. After regeneration, the regenerated CO 2 rich phase combines CO 2 lean phase to form absorbent again to complete the cycle. The advantage for Phase Transitional Absorption is obvious, significantly saving on regeneration energy. Because CO 2 lean phase was separated before regeneration, only CO 2 rich phase was forward to regeneration. The absorption system we developed has the features of high absorption rate, high loading and working capacity, low corrosion, low regeneration heat, no toxic to environment, etc. The process evaluation shows that our process is able to save 80 % energy cost by comparing with MEA process.

“…It has been used for natural gas treatment or in refineries for several decades, and corrosion has always been considered as one of the major operational problems [4][5][6][7][8][9][10][11]. In the eighties, several industrial failures in gas treating plants were reported, the most important one causing the death of 17 employees [12][13][14].…”

Re´sume´-Corrosion dans les proce´de´s utilisant des alcanolamines pour le captage du CO 2 en post-combustion -Les proce´de´s de captage et de stockage du CO 2 occupent une place importante dans les strate´gies visant a`limiter les e´missions industrielles de gaz a`effet de serre. Les proce´de´s de captage en post-combustion par solvant chimique de type alcanolamine sont bien adapte´s au traitement d'e´missions ponctuelles massives issues de combustibles fossiles, rencontre´es notamment dans les centrales thermiques au charbon et au gaz, ou les industries side´rurgiques ou de production de ciment. La technologie utilisant le principe d'absorptionde´sorption par les alcanolamines est une des voies les plus matures a`ce jour : elle est en effet de´ja`mise en oeuvre, par exemple pour la de´sacidification du gaz naturel, bien qu'a`une e´chelle sensiblement plus petite. L'ope´ration de telles unite´s pour le traitement des fume´es de combustion pre´sente toutefois de nombreux challenges, parmi lesquels la corrosion des e´quipements tient une place importante. Le but de cet article est de pre´senter une revue des connaissances sur cet aspect particulier. Dans une premie`re partie, l'expe´rience issue de plusieurs de´cennies d'utilisation de proce´de´s aux alcanolamines dans le domaine de la production d'huile et de gaz est pre´sente´e. Dans une seconde partie, les risques spe´cifiques associe´s aux particularite´s des proce´de´s de captage du CO 2 en post-combustion sont identifie´s et discute´s. Diffe´rentes strate´gies de maıˆtrise de la corrosion sont de´crites, et certains axes prioritaires en matie`re de recherche et de´veloppement sont propose´s. Enfin, certaines difficulte´s en vue du transport du CO 2 issu du captage puis de son injection a`fin de stockage ge´ologique sont mises en avant, avec des recommandations strictes sur les teneurs maximales en impurete´s pour disposer en toute surete´du CO 2 issu de ce proce´de´.Abstract -Corrosion in CO 2 Post-Combustion Capture with Alkanolamines -A Review -CO 2 capture and storage plays an important part in industrial strategies for the mitigation of greenhouse gas emissions. CO 2 post-combustion capture with alkanolamines is well adapted for the treatment of large industrial point sources using combustion of fossil fuels for power generation, like coal or gas fired power plants, or the steel and cement industries. It is also one of the most mature technologies to date, since similar applications are already found in other types of industries like acid gas separation, although not at the same scale. Operation of alkanolamine units for CO 2 capture in combustion fumes presents several challenges, among which corrosion control plays a great part. It is the aim of this paper to present a review of current knowledge on this specific aspect. In a first part, lessons learnt from several decades of use of alkanolamines for natural gas separation in the oil and gas industry are discussed. Then, the specificities of CO 2 post-combustion capture are presented, and their conseq...
