“…To solve the problem of ammonia loss, Hamed Rashidi et al developed an ammonia-glycerol hybrid solvent to capture CO 2 glycerol, which is a byproduct of biodiesel has hydroxyl groups which can bind ammonia molecules and hence the vaporization of ammonia reduces. Their experimental output reveals that applying glycerol with aqueous ammonia causes an increase in the mass transfer coefficient and a reduction in the vapor pressure of ammonia that results in lower losses of ammonia in the CO 2 capture system [36].…”

CO2 capture, use, and storage have been identified as significant strategies for reducing greenhouse gas emissions induced by the usage of fossil fuels. The current review focuses on the concepts of post-combustion capture technologies based on absorption mechanisms. Among all other developed technologies, researchers have proposed absorption as the most mature carbon capture technology for industrial-scale application. Absorption-based carbon capture can be classified into chemical and physical absorption, and researchers have developed different solvents and absorbent materials to investigate their performance in CO2 capture. This paper comprehensively reviewed these established solvents and absorbents with their performance parameters in the CO2 absorption approach. Besides the improvement in widely applied absorbents such as amine-based absorbents, recently, researchers have been working to develop some advanced nanomaterials such as nanofluids and nano-emulsions. This review focuses on the application of such absorption mechanisms that can contribute to capturing CO2 in a compact, environment-friendly, and safe way. This paper also provides future research direction for further development in absorption-based CO2 capture.

The core for carbon dioxide capture is the development of green solvents for absorption processes.The current research aims at the CO2 capture process from a gas stream in a micro-contactor using an amino acid-based green technology containing diethanolamine (DEA) and L-arginine (ARG) solutions. The gas-liquid mass transfer performance has been experimentally assessed in terms of CO2 absorption efficiency (%) and volumetric gas-phase mass transfer coefficient (KGaV). The measurements have been carried out under liquid flow rate (QL: 3.0-9.0 ml/min), gas flow rate (QG: 120.0-300.0 ml/min) at a constant temperature of 45 °C, and atmospheric pressure. The aqueous composition of the blended solution was DEA ARG (35 0 wt%), DEA ARG (31 4 wt%), DEA ARG (27 8 wt%), and DEA ARG (23 12 wt%). It was found that an increase in the solvent flow rate from 3.0 to 9.0 ml/min enhanced the absorption efficiency, KGaV, and NGaV by 2.5%, 12.8%, and 2.6%, respectively. However, an increase in the gas flow rate from 120.0 to 300.0 ml/min reduced the efficiency by 6% but improved the KGaV and NGaV by 88% and 225%, respectively. Additionally, the KGaV values followed a declining trend as the contribution of the DEA in the blended solution increased. Based on RSM modeling, the correlations for predicting the KGaV and CO2 absorption efficiency into blended DEA-Arg were successfully established
