This research is necessary to provide a potential aqueous amine blend solvent for industrial application to help in overcoming the challenges of drastic climate change. The performance of a novel aqueous amine blend of 2-(butylamino)ethanol (BAE) and 2-Dimethylaminoethanol (DMAE) in terms of CO₂ absorption and desorption was investigated. This study focused on aspects such as equilibrium CO₂ loading, absorption capacity, empirical modeling, cyclic equilibrium CO₂ loading, cyclic capacity, heat duty, regeneration efficiency, pH effect, heat of absorption, toxicity assessment, ¹³C NMR and FTIR speciation, response surface methodology (RSM) modeling, and optimization. The entire CO₂ absorption experiment was performed in the temperature (T) ranging from 298.15 to 333.15 K, CO₂ partial pressure (${\mathrm{P}}_{\mathrm{C}\mathrm{O}2}$) ranged from 10.13 to 25.33 kPa, mole fraction of BAE (${\mathrm{m}}_{\mathrm{B}\mathrm{A}\mathrm{E}}$) changed from 0.05 to 0.20, and solution concentration (C) varied from 1 to 3 mol/L. Desorption experiments were carried out at a constant temperature of 393.15 K and a constant pressure of 25.33 kPa. At T = 313.15 K, ${\mathrm{P}}_{\mathrm{C}\mathrm{O}2}$ = 25.33 kPa, ${\mathrm{m}}_{\mathrm{B}\mathrm{A}\mathrm{E}}$ = 0.20, and C = 1 mol/L, CO₂ absorption experiments yielded a maximum equilibrium CO₂ loading of 0.9365 mol CO₂/mol amine. At C = 3 mol/L, this novel blend exhibited 71.23 % higher cyclic capacity than conventional 30 wt% monoethanolamine (MEA). Heat duty and regeneration efficiency of 3 mol/L solution were found to be 112.96 kJ/mol CO₂ and 83.27 %, respectively. This amine blend's heat of CO₂ absorption was determined to be −72.74 kJ/mol. RSM predicted optimum equilibrium CO₂ loading of 0.829265 mol CO₂/mol amine at T = 306.90 K, ${\mathrm{P}}_{\mathrm{C}\mathrm{O}2}$ = 21.22 kPa, ${\mathrm{m}}_{\mathrm{B}\mathrm{A}\mathrm{E}}$ = 0.16, and C = 1.5 mol/L.
