This work assessed the carbon dioxide capture performance of different aqueous amines, in comparison to standard amine monoethanolamine (MEA), the standard for the capture process, A continuous operation was implemented, and a packed column served as the scrubber to develop effective sorbents for carbon capture and separation (CCS). The impact of operating variables such as carbon dioxide loading, feed amine temperature, solvent amine weight concentration, simulated gas flow rate, carbon dioxide feed concentration, amine type, and liquid flow rate was examined. Carbon dioxide concentration; absorption efficiency and overall mass transfer coefficient measurement as an indicator for the effectiveness of the capture process. For each system, the overall amine concentration was maintained at 30 weight percent and the treating a gas mixture containing 15% carbon dioxide (by volume) mimicking a fossil-derived flue gas. according to the findings of the experimental result that the raising of the efficiency of Carbon dioxide removal rises with rising amine concentration and amine flow rate; on the other side, the efficiency of carbon dioxide removal reduced with increasing gas flow rate, lean amine temperature, and lean amine temperature. The maximal carbon dioxide removal coefficients achieved by DETA and I-BA aqueous amine solutions under ideal circumstances are 90% and 76%, respectively. Additionally, at given the experiment's operating conditions, the highest volumetric total gas-phase mass transfer coefficient was found to be 0.25 and 0.24 (kmol/m3 h kpa), respectively.
