“…The main reaction considered here consists of amine deprotonation, carbamate formation by APDA as well as bicarbonate formation. Since APDA consists of primary and secondary amine group, it follows mostly zwitterion mechanism and forms stable carbamates as the reaction products as reported by Das et al 16 Bicarbonate is the prime reaction product of CO 2 -MDEA/AMP system along with other products discussed here. The overall equilibrium reactions considered in the present work are expressed as:…”

The utility of polyamine-based solvent-activators for the possible application in postcombustion CO 2 capture technology has drawn considerable attention recently owing to its higher loading capacity as well as superior kinetics. The current work involves a comprehensive experimental cum theoretical investigation on the equilibrium solubility of CO 2 pertaining to aqueous N-(3-aminopropyl)-1,3-propanediamine and its blends with Nmethyldiethanolamine and 2-amino-2-methyl-1-propanol. The analysis was conducted within the operating temperature and CO 2 partial pressure range of 303.2-323.2 K and 2-200 kPa, respectively. Two different mathematical models based on nonrigorous approaches such as equilibrium based modified Kent-Eisenberg (KE) model and a multilayer feedforward neural network model have been developed to correlate the CO 2 solubility data over a wide range of experimental conditions. Both the model predictions are wellvalidated with the experimental results. The reaction scheme as well as the prevalence of important reaction products was further confirmed with qualitative 13 C NMR as well as ATR-FTIR analysis. Apart from these some of the important thermally induced transport properties viz, density, viscosity, and surface tension of the aqueous single and blended systems were measured and correlated with various consistent empirical models such as Redlich-Kister and Grunberg-Nissan model while surface tension data are modeled using temperature-based multiple linear regression technique.

Post‐combustion CO₂ capture with chemical absorption and hybrid system: current status and challenges

Post-combustion CO 2 capture from the power and industrial sectors has gained widespread attention due to its ability to retrofit easily with newly installed and existing plants. This state-of-the-art, updated review provides an overview of technical issues in post-combustion CO 2 capture related to process performance, energy requirements for CO 2 capture, and inconsistencies in the prediction of CO 2 capture cost. Recent updates are presented regarding chemical absorption-desorption systems, and particularly CO 2 absorption and solubility enhancement studies, absorber operation at elevated pressure, recent developments in absorber configuration, and methods for reducing the heat duty of strippers. Furthermore, recently developed post-combustion hybrid techniques such as the membrane-absorbent hybrid process, the membrane-cryogenic hybrid process, the membrane-adsorption hybrid process, the absorption-electrolysis hybrid process, and the solar thermal electrochemical process (STEP) are discussed. Finally, we suggest areas for improvement and indicate that there are significant future prospects for post-combustion CO 2 capture. C

“…CO 2 capture from large anthropogenic sources by scientific way and climate‐friendly modern solutions is one of the promising options to control its concentration in atmosphere and make it below the permissible limits. Aqueous amines such as monoethanolamine (MEA) and its blends based absorption process is one of the emerging technology for CO 2 capture . Other alternatives such as porous solid based adsorption process may provide better energy performance in form of CO 2 capacity and faster rate of regeneration.…”

In this study, covalent organic cages (COC‐MI, COC‐PI and COC‐PA) with covalently imine linked molecules were developed for CO2 adsorption. By varying the organic linkers (iso‐phthalaldehyde to para‐phthalaldehyde) tuned the structure and extrinsic porosity such as specific surface area of the organic cages was demonstrated. Additionally, COC‐PI (3.8 cm3/g to 5.7 cm3/g) and COC‐PA (0.43 cm3/g to 0.48 cm3/g) showed the significantly enhancement in CO2 adsorption capacity with increase in temperature from 273 K to 298 K at 1 bar. On the other hand, COC‐MI (1.17 cm3/g to 1.1 cm3/g) cage showed the significant reduction in CO2 adsorption capacity with increase in temperature from 273 K to 298 K at 1 bar. These unusual enhancements of CO2 adsorption capacity within COC‐PI and COC‐PA is elucidated by powder X‐ray diffraction (PXRD), and it is shown that cooperative diffusion and induced crystal lattice expansion in these molecular crystals can enhance the CO2 adsorption capacity. Computational modelling on the COC cages with CO2 reveals the higher binding energy and rigidity at the C=N group during intermolecular interactions enhances the overall CO2 adsorption capacity in the bulk.
