摘要

The removal efficiency of carbon dioxide from gases containing 10% CO_2 by the aqueous solutions containing piperazine(PZ)and its mixture with monoethanolamine(MEA),2-amino-2-methyl-l-propanol(AMP),and methyldiethanolamine(MDEA)in a rotating packed bed was investigated in this study.The efficiency was assessed in terms of an overall volumetric mass transfer coefficient(K_Ga)that was found to be a strong function of gas and liquid flow rates.The obtained results indicated that PZ was the most effective absorbent over MEA,AMP,and MDEA.This was attributed to a high reaction rate of PZ with CO_2.The mixed amines containing PZ and MEA as well as PZ and AMP exhibited a high CO_2 removal efficiency as well.A higher portion of PZ in the mixture was more favorable to CO_2 absorption.The mixture of PZ with MDEA,however,was found not to be appropriate due to a low reaction activity of MDEA with CO_2.The CO_2 removal efficiency in a rotating packed bed was also observed to be more effective than that in a packed tower,implying a great potential of a rotating packed bed applied to the reduction of the greenhouse gas CO_2 from the exhausted gases.
