摘要: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 CO2removal 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 CO2from the exhausted gas. The mixture containing PZ and DETA exhibited a high CO2removal efficiency among these absorbents. Besides, DETA has a lower regeneration heat duty than MEA, which means the finest mixture for industrial CO2capture system will be the combination of PZ, DETA, and ionic liquids, instead of traditional alkanolamines, MEA.
