“…The titration technique was adopted to determine the amine dissociation constant (Ka) with standard 1 mol/L HCl [32,33,34,35]. This is a simplified pH method to test the pKa of different amines under different temperatures.…”

“…The pH meter was used to measure the concentration of H + in the solution [32,33,34,35]. As presented in Equation (23), the disappearance of H + during the titration process resulted from its reaction with Amine to generate AmineH + , and reaction (20) is the dominant in aqueous solution.…”

“…As part of the pivotal desorption parameter [9,26,33], the heat duties were calculated from CO 2 production with Equations (26) and (27) below [9,21,26]. The nCO 2 (mol) is the amount of desorbed CO 2 , α (mol of CO 2 per mole of amine) is the CO 2 loading, and C (mol/L) and V (L) are the concentration and volume of amine solvent.…”

Studies of catalytic CO2 absorption and desorption were completed in two well-performed tertiary amines: diethylmonoethanolamine (DEEA) and 1-dimethylamino-2-propanol (1DMA-2P), with the aid of CaCO3 and MgCO3 in the absorption process, and with the aid of γ-Al2O3 and H-ZSM-5 in the desorption process. The batch process was used for CO2 absorption with solid alkalis, and the recirculation process was used for CO2 desorption with solid acid catalysts. The CO2 equilibrium solubility and pKa were also measured at 293 K with results comparable to the literature. The catalytic tests discovered that the heterogeneous catalysis of tertiary amines on both absorption and desorption sides were quite different from monoethanolamine (MEA) and diethanolamine (DEA). These results were illustrative as a start-up to further study of the kinetics of heterogeneous catalysis of CO2 to tertiary amines based on their special reaction schemes and base-catalyzed hydration mechanism.

“…They believed that blending amine solvents would utilize the potential of individual solvents in the blend while reducing their individual shortcomings to achieve better overall performance. Since then, a lot of research has been devoted to amine blends . To improve the absorption performance of MEA, researchers added various types of amines to MEA, such as MDEA, 2‐amino‐2‐methyl‐1‐propanol (AMP), triethanolamine (TEA), benzylamine (BZA), etc.…”

The carbon dioxide post‐combustion capture process using amine solutions is considered the most appropriate method for CO2 capture from flue gas in power plants. This paper focuses on the CO2 capture performance of six common organic amines. Two amines, piperazine (PZ) and diethylenetriamine (DETA), which showed better performance, were then filtered out to form amine blends to improve performance further. The absorption heat from the CO2 absorbing process was measured directly using an advanced C80 micro calorimeter for more accurate calculation of regenerative energy consumption. Experimental results confirmed the optimal amine blend to be 10% PZ plus 20% DETA, with a 42% increase in absorption capacity and a 9% increase in initial absorption rate compared to traditional 30% monoethanolamine (MEA). The regeneration energy consumption of this chosen PZ‐DETA blend was calculated to be 3.979 GJ/ton CO2, a decrease of 9% compared with MEA. Moreover, it led to an improvement of about 55% in stable cyclic absorption capacity in comparison with 30% MEA. It was confirmed that this PZ‐DETA blend can bring practical economic benefits to industrial applications when replacing the current 30% MEA solution. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
