在这项研究中，研究了在旋转填充床中从含有1 - 10 mol % CO2的气体中吸收二氧化碳。以氢氧化钠、单乙醇胺和2-氨基-2-甲基-1-丙醇的水溶液为吸收剂。的整体体积传质系数（KGa），观察作为旋转速度，气体流量，液体流量，吸收剂浓度，和CO2浓度的函数。结果表明，旋转填料床的KGa与EX填料塔的KGa相当，说明旋转填料床应用于温室气体CO2减排具有很大的潜力。
The absorption of carbon dioxide from gases containing 1−10 mol % CO2 in a rotating packed bed was investigated in this study. The aqueous solutions of NaOH, monoethanolamine, and 2-amino-2-methyl-1-propanol were used as the absorbents. The overall volumetric mass-transfer coefficient (KGa) was observed as a function of the rotating speed, gas flow rate, liquid flow rate, absorbent concentration, and CO2 concentration. The obtained results indicated that KGa of a rotating packed bed was comparable to a tower packed with the EX packing, implying a great potential of a rotating packed bed applied to the reduction of the greenhouse gas CO2 from the exhausted gases.
