Carbon dioxide absorption in a cross-flow rotating packed bed

Abstract This work investigates the feasibility of applying the cross-flow rotating packed bed (RPB) to the removal of carbon dioxide (CO 2 ) by absorption from gaseous streams. Monoethanolamine (MEA) aqueous solution was used as the model absorbent. Also, other absorbents such as the NaOH and 2-amino-2-methyl-1-propanol (AMP) aqueous solutions were compared with the MEA aqueous solution. The CO 2 removal efficiency was observed as functions of rotor speed, gas flow rate, liquid flow rate, MEA concentration, and CO 2 concentration. Experimental results indicated that the rotor speed positively affects the CO 2 removal efficiency. Our results further demonstrated that the CO 2 removal efficiency increased with the liquid flow rate and the MEA concentration; however, decreased with the gas flow rate and the CO 2 concentration. Additionally, the CO 2 removal efficiency for the MEA aqueous solution was superior to that for the NaOH and AMP aqueous solutions. Based on the performance comparison with the conventional packed bed and the countercurrent-flow RPB, the cross-flow RPB is an effective absorber for CO 2 absorption process.
