| description | This work focused on the application of a microchannel contactor for CO<sub>2</sub> capture using water as absorbent, especially for the application of CO<sub>2</sub>-rich gas. The influence of operating conditions (temperature, volumetric flow rate of gas and liquid, and CO<sub>2</sub> concentration) on the absorption efficiency and the overall liquid-side volumetric mass transfer coefficient was presented in terms of the main effects and interactions based on the factorial design of experiments. It was found that 70.9% of CO<sub>2</sub> capture was achieved under the operating conditions as follows; temperature of 50 °C, CO<sub>2</sub> inlet fraction of 53.7%, total gas volumetric flow rate of 150 mL min<sup>−1</sup>, and adsorbent volumetric flow rate of 1 mL min<sup>−1</sup>. Outstanding performance of CO<sub>2</sub> capture was demonstrated with the overall liquid-side volumetric mass transfer coefficient of 0.26 s<sup>−1</sup>. Further enhancing the system by using 2.2 M of monoethanolamine in water (1:1 molar ratio of MEA-to-CO<sub>2</sub>) boosted the absorption efficiency up to 88%. |
