ISBN:

Book Description
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.
Absorption-Based Post-Combustion Capture of Carbon Dioxide
Author: Paul FeronPublisher: Woodhead Publishing
ISBN: 0081005156
Category : Technology & Engineering
Languages : en
Pages : 816
Book Description
Absorption-Based Post-Combustion Capture of Carbon Dioxide provides a comprehensive and authoritative review of the use of absorbents for post-combustion capture of carbon dioxide. As fossil fuel-based power generation technologies are likely to remain key in the future, at least in the short- and medium-term, carbon capture and storage will be a critical greenhouse gas reduction technique. Post-combustion capture involves the removal of carbon dioxide from flue gases after fuel combustion, meaning that carbon dioxide can then be compressed and cooled to form a safely transportable liquid that can be stored underground. - Provides researchers in academia and industry with an authoritative overview of the amine-based methods for carbon dioxide capture from flue gases and related processes - Editors and contributors are well known experts in the field - Presents the first book on this specific topic
Corrosion in CO2 Absorption Process Using Aqueous Monoethanolamine/piperazine Solution
Author: Manjula NainarPublisher:
ISBN:
Category : Amines
Languages : en
Pages : 312
Book Description
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.

Carbon Dioxide Chemistry, Capture and Oil Recovery

Category : Science
Languages : en
Pages : 268
Book Description
Fossil fuels still need to meet the growing demand of global economic development, yet they are often considered as one of the main sources of the CO2 release in the atmosphere. CO2, which is the primary greenhouse gas (GHG), is periodically exchanged among the land surface, ocean, and atmosphere where various creatures absorb and produce it daily. However, the balanced processes of producing and consuming the CO2 by nature are unfortunately faced by the anthropogenic release of CO2. Decreasing the emissions of these greenhouse gases is becoming more urgent. Therefore, carbon sequestration and storage (CSS) of CO2, its utilization in oil recovery, as well as its conversion into fuels and chemicals emerge as active options and potential strategies to mitigate CO2 emissions and climate change, energy crises, and challenges in the storage of energy.

Book Description
This study focused on utilizing the combined effect between solvent development and the application of solid catalysis to enhance the reactive absorption-based CO2 capture process. First, the CO2 removal performance of three formulated amine bi-blends were evaluated using a semi-batch screening setup. The performance of each blend in terms of specific parameters such as linear absorption and desorption rates, CO2 equilibrium loading, cyclic capacity and solvent regeneration heat duty were compared with the activity of the standard 4M BEA/AMP blend. The bi-blends developed included 2M HMDA/PEI (1.85M: 0.15M), 2M AMP/PEI (1.7M: 0.3M) and 4M DMAE/AMP (2M: 2M). The screening results showed that by reason of higher reactivity resulting from increased number of amino groups in HMDA and PEI, better absorption performance was observed for 2M HMDA/PEI and 2M AMP/PEI bi-blends. However, from the absorption parameter and desorption parameter criterion, 4M DMAE/AMP was found to be the optimum bi-blend amongst the three blends. In addition, the effects of solid alkaline and acid catalysts on the CO2 absorption and desorption performance of the selected optimum blend were studied. Also, the different characteristics of the catalysts were investigated and related to the corresponding enhancement activity to identify and establish the activity-characteristics relationship. Employing the acid proprietary desorber catalyst (AD-1) increased the linear desorption rate and cyclic capacity of 4M DMAE/AMP by 21% and 8.1% respectively and reduced the solvent regeneration energy requirement by 17.3%. Between the absorber catalysts, an increase of 33.3% and 29% in absorption rates were measured for ACS and AB-1 respectively. Comparing the activity of ACS to AB-1, it was observed that the activity of catalyst depends on both the chemical properties (strength and number of basic sites) and physical properties (surface area and pore volume). Furthermore, a full cycle operation in a bench-scale CO2 capture unit was carried out to validate the performance of 4M DMAE/AMP and 2M HMDA/PEI bi-blends. The performance was evaluated as a function of time-on-stream. From the cyclic runs, higher CO2 absorption and desorption performance parameters were recorded for 4M DMAE/AMP relative to the 2M HMDA/PEI blend. The time-on-stream analysis revealed a general reduction in capture performance and an increase in heat duty for both bi-blends.
