Abstract

The CO2 desorption tests were conducted at 363–378 K for 5.0 mol/L blended monoethanolamine (MEA)‐diethanolamine (DEA) solutions to develop the energy efficient solvents with high CO2 production and low energy consumptions. These desorption tests were performed with a recirculation process for various preloaded, 5 mol/L (4.5 + 0.5 to 0.5 + 4.5) MEA‐DEA solutions to find out the optimized solvents with minimum heat duty. Therefore, 1–4 mol/L and 0.5–0.45 mol/L MEA‐DEA solvents have larger CO2 production (nCO2) and lower heat duties ( HCO2) than 5 mol/L DEA under similar operation conditions. They have lower heat duty (510 and 538 kJ/mol) than DEA (572 kJ/mol) due to increased CO2 desorption rates, despite 10% higher heat input (QTotal) than DEA. Moreover, the critical points were studied as research focus of amine regeneration curves, along with reaction energy calculation. Finally, secondary amines blending minor MEA (<20%) as promotor turned out to be an alternative approach of solvents improvement with low energy requirement.
