This study investigates the removal efficiency of carbon dioxide by aqueous absorbents containing monoethanolamine (MEA), piperazine(PZ), diethylenetriamine(DETA) and ionic liquids in a rotating packed bed. The performance of an absorbent was assessed in terms of an overall volumetric mass transfer coefficient and regeneration heat duty. The CO2 removal efficiency in a rotating packed bed was observed to be more suitable than that in a packed column, suggesting a potential of a rotating packed bed can replace a traditional packed column to the usage of reduction of the greenhouse gas CO2 from the exhausted gas. The mixture containing PZ and DETA exhibited a high CO2 removal efficiency among these absorbents. Besides, DETA has a lower regeneration heat duty than MEA, which means the finest mixture for industrial CO2 capture system will be the combination of PZ, DETA, and ionic liquids, instead of traditional alkanolamines, MEA.

Based on acetone-H2O system, the influence of the gas-liquid distribution inducer on the mass transfer coefficient in the rotating packed bed with the stainless steel packing was investigated. Furthermore, the absorption performance was also obtained under the experimental condition of the rotational speed of 630 rpm, the gas flow rate of 2 m3/h and the liquid flow rate of 100 L/h in the rotating packed bed with different types and different installation ways of the distribution inducer. The experimental results showed that the volumetric mass transfer coefficient Kyα per unit contact length of gas-liquid was increased by 8.6% for the forward-curved fixed blade, by 19.8% for the backward-curved rotor blade and by 33.2% with the combination of the straight radial rotor blade and the backward-curved fixed blade, respectively. Furthermore, when the gas flow rate was 2.5 m3/h, Kyα per unit contact length of gas-liquid was increased by 2.9% for the forward-curved fixed blade, by 25.3% for the backward-curved rotor blade, by 42.7% for the combination of the straight radial rotor blade and the backward-curved fixed blade, respectively. The results indicated that the distribution inducer play an important role on the improvement of the mass transfer coefficient in acetone-H2O system.
