“…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.…”

“…After the absorption profiles were plotted with (α, time), the initial absorption rates (I abs_rate , mol CO 2 /min) [34] are determined as the slope of the linear regression of absorption profiles was at data range of CO 2 loadings of 0.0–0.20 mol/mol, in Equation (25): Iabs_rate=normalC×Vdαdt where “C” is the Concentration and “V” is the Volume, and α is the CO 2 loading.…”

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.

“…Muchan et al [191] tested and compared amines in the aspect of the rate of absorption and desorption, pKa, the partial pressure of CO2, the heat of regeneration, and heat of absorption. They reported that due to the negative electron withdrawing effect of the hydroxyl groups, amines with more hydroxyl groups showed lower performance in all the CO2 capturing activities.…”

Solvent selection and design are imperative in the CO2 capture process. The efficiency and the overall cost of the process are directly affected by the solvent as a consequence of the effect of solvent on factors such as CO2 absorption capacity, size of equipment, and solvent regeneration energy. This review paper aims to review the most important solvents and mixtures of solvents, absorbing CO2 via chemisorption, physisorption and chemi-physisoprtion. Characteristic and structure of different solvents are presented with the advantages and disadvantages of each being highlighted. Mixtures of solvents include chemical or physical solvents only, and combinations of physical and chemical solvents are categorised. In addition to common solvents, phase change solvents are also described. Once a comprehensive list of solvents is presented, different methods of solvent selection and design are illustrated, namely methods involving experiments, process and equilibrium models, predictive models, and computer-aided molecular design (CAMD). The importance of integrated solvent and process selection and design is also discussed. The most recent and selected progress studies in each section are reviewed in detail.

“…Muchan et al . (2017) experimentally performed screening test of primary, secondary, and tertiary amines for the appropriate selection of blended solution. They suggested the optimal blended solution for CO 2 absorption and desorption on the basis of CO 2 solubility, absorption rate, desorption, rate and heat duty.…”

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

et al. 2018

View full text Add to dashboard Cite

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
