This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter evaluated the performance of environmentally friendly organic corrosion inhibitors on carbon steel in the amine-based carbon dioxide (CO2) absorption process. The evaluation was experimentally conducted using electrochemical techniques in 5.0 kmol/m3 monoethanolamine (MEA) solutions in the absence and presence of process contaminants, namely formate and chloride, at 80°C and 0.55 mol/mol CO2 loading. The results show, in the absence of process contaminants, that 2-aminobenzene sulfonic acid, 3-aminobenzene sulfonic acid, 4-aminobenzene sulfonic acid, sulfapyridine, and sulfolane yielded 85-92% corrosion inhibition efficiencies, while sulfanilamide yielded the lowest efficiency of 20-42%. Sulfolane was the only tested inhibitor whose performance could be maintained in chloride- and formate-containing MEA solutions. On the contrary, the performance of 3-aminobenzene sulfonic acid and sulfapyridine was decreased by chloride. The performance of all the tested aminobenzene sulfonic acids was compromised by formate.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of process equipment and piping in the amine-based carbon dioxide (CO2) absorption process causes considerable expenditures for maintenance and repair. The addition of effective corrosion inhibitors to the amine solutions is a common practice for corrosion mitigation. Despite their inhibition effectiveness, those corrosion inhibitors used in the amine-based CO2 absorption process are not environmentally friendly and require costly waste handling and disposal. To reduce such cost and prepare for more stringent environmental regulations for chemical uses and disposal, this work investigated the feasibility of using condiments as environmentally friendly corrosion inhibitors in the amine-based CO2 absorption process. In this study, five condiments including powders of garlic, mustard, horseradish, onion and turmeric were selected and evaluated for their corrosion inhibition performance on carbon steel (CS1018) in the environment of 5.0 kmol/m3 aqueous solutions of monoethanolamine (MEA) saturated with dissolved CO2. The evaluation was carried out in corrosion experiments that employed cyclic and poteniodynamic polarization and electrochemical impedance spectroscopy for corrosion measurement and analysis. Results show that the powders of garlic, mustard, horseradish, onion showed great promise for corrosion reduction in both MEA-CO2 and MEA-CO2-oxygen (O2) solutions. They performed well with inhibition efficiencies in the range of 80- 95% even at elevated temperatures and the presence of process contaminants (i.e., chloride and oxalate) which were found to slightly affect the inhibition performance. These four condiments were proved to be mixed-type (anodic and cathodic) corrosion inhibitors that protected the metal surface by undergoing endothermic physical and chemical adsorption with the Langmuir adsorption isotherm. Sulfur, nitrogen, phosphorus functional groups were the primary contributors to the inhibition effectiveness. Unlike these four condiments, the powder of turmeric was not promising as it yielded lower inhibition efficiency and induced pitting corrosion for most tested conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Inorganic corrosion inhibitors including heavy metals have been widely used in the carbon dioxide (CO2) absorption process for corrosion control. However, they are not environmentally friendly causing costly handling and disposal costs. This work therefore evaluated corrosion inhibition performance of an organic amino acid compound, namely Methionine (MTI) which is less toxic, more readily biodegradable, and has lower potential for bioaccumulation in aquatic organisms compared to common amine absorption solvents. The evaluation was experimentally implemented using electrochemical and weight loss methods. Carbon steel (CS1018) and 5.0 kmol/m3 Monoethanolamine (MEA) purged with 85% CO2 and 15% oxygen (O2) were used as tested material and absorption solution, respectively. The electrochemical results showed that at solution temperatures up to 80oC, MTI effectively reduced corrosion rates of CS1018 with maximum inhibition efficiencies of 83.56% ± 1.82% under a static condition (0 rpm) and 74.96% ± 0.95% under a dynamic condition (1500 rpm). Its inhibition performance was found to increase with inhibitor concentration and solution temperature but decrease with rotational speed. MTI acted as a mixed-type inhibitor and exhibited pitting tendency. The optimal MTI concentrations were 1500 ppm at 0 rpm and 2000 ppm at 1500 rpm. The post data analysis involving adsorption isotherm and activation thermodynamic properties revealed that MTI protected metal surface by undergoing spontaneous and endothermic physical adsorption. Its adsorption characteristic matched well with the Langmuir adsorption isotherm, thereby suggesting that MTI formed a protective monolayer on the metal surface. The results of quantum chemical analysis suggested MTI has higher affinity, polarizability, and electron donating ability than MEA. III The results of weight loss experiments carried out for up to 28 days showed that at 120oC, 5 bar and 1500 rpm, MTI was able to reduce corrosion rates of CS1018 to below 1 mmpy. The inhibition efficiencies were up to 78.7% for carbon steel specimens fully immersed in the MEA solutions, 53.5% for those partially immersed in the MEA solution and partially exposed to vapor, and 85.6% for those fully exposed to vapor. Pits were observed on carbon steel specimens fully immersed in both uninhibited and MTI inhibited solutions.

Download or read book Corrosion in CO2 Absorption Process Using Aqueous Monoethanolamine piperazine Solution written by Manjula Nainar and published by . This book was released on 2007 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work explores the promise of aqueous solutions of blended monoethanolamine (MEA) and piperazine (PZ) as a cost-effective solvent for carbon dioxide (CO2) capture from industrial flue gas streams with respect to addressing corrosion, which is regarded as one of the most severe operational problems in typical CO2 capture plants. Two types of corrosion experiments were carried out in bench-scale setups, electrochemical tests for short-term exposure and weight loss tests for long-term exposure. The results show that the blended MEA/PZ solutions are more corrosive than the MEA solutions. The corrosion rate of carbon steel increases with concentration of PZ, total amine concentration, CO2 loading of solution, solution temperature, the presence of heat stable salts, and the presence of the proprietary oxidative degradation inhibitor (Inhibitor A provided by the University of Texas at Austin). Among the tested heat-stable salts, formate is the most corrosive salt, followed by acetate, oxalate, and thiosulfate in the absence of oxygen (O2), while acetate is the most corrosive salt followed by formate, oxalate, and thiosulfate in the presence of O2. Based on the level of corrosion rate found in the MEA/PZ system, corrosion control is required during plant operation to suppress the corrosion rate of carbon steel to below an acceptable level. Sodium metavanadate (NaVO3) and copper carbonate (CuCO3) were proven to be effective corrosion inhibitors with inhibition performance of up to 94-98%. Dissolved O2 is required in the solution to maintain active Cu2 or V5+, which, thus, prevents the metallic copper (Cu) from plating out or the formation of other oxidative states of vanadate. The performance of these two inhibitors can be deteriorated by the presence of heat-stable salts in the solutions.

Download or read book Novel Corrosion Inhibitors for Protection from CO2 Corrosion written by Hany M. Abd El-Lateef and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide (CO2) corrosion is of great concern in oil and gas production, transportation and processing. Despite the fact that steel has low resistance to CO2 environments, it is widely used in the petroleum industry mainly due to economical reasons. The use of corrosion inhibitors is very important in the protection of steels. Most of the inhibitors used in petroleum industry are organic compounds containing multiple bonds in their molecules that mainly contain nitrogen, sulphur, and/or oxygen atoms through which they get adsorbed on the metal surface. However, most of these substances are toxic and using them is harmful for both human health and environment. Therefore, in this work, we accomplished synthesis of new environment friendly effective corrosion inhibitors for oil and gas industry in the protection of equipment and pipelines transporting multiphase systems based on vegetable oils. Vegetable oils are of the greatest interest because of its technological properties, accessibility, and relatively low price. The performed research is indicating that the vegetable oil can be good raw material for preparation of "environmentally friendly" corrosion inhibitors.

This book was released on 2007 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion is one of the most severe operational problems in CO2 absorption processes, which use aqueous solutions of alkanolamines, especially when carbon steel is used for plant construction. Corrosion inhibitors are widely applied used in this process to suppress severe corrosion to an acceptable level. However, currently available corrosion inhibitors are heavy metals, which are toxic to human health and the environment, making solvent handling and waste disposal more difficult and costly. This work evaluated a low-toxic corrosion inhibitor, copper carbonate (CuCO3), as a replacement for toxic corrosion inhibitors. An inhibition evaluation was performed on copper carbonate by examining its parametric effects on the corrosion rate and corrosion behavior of carbon steel.
