Removal of Carbon Dioxide from Indoor Air Using a Cross- Flow Rotating Packed Bed
Year: 2013
Type: conference-paper
Abstract: This investigation elucidated the performance of the cross-flow rotating packed bed (RPB) in removing carbon dioxide (CO 2 ) from indoor air by chemical absorption. MEA, NaOH, K 2 CO 3 aqueous solutions were used as the model absorbents. The results of this investigation demonstrated that the removal efficiency of CO 2 increased with rotational speed and liquid flow rate, but decreased with gas flow rate. Furthermore, the removal efficiency of CO 2 could be enhanced when H 2 O 2 with an appropriate concentration was added to the K 2 CO 3 aqueous solution. The removal efficiency of CO 2 was found with the order: 1.0 mol/L MEA = 1.0 mol/L NaOH > 5 wt% K 2 CO 3 /0.20 mol/L H 2 O 2 > 5 wt% K 2 CO 3 /0.1 mol/L H 2 O 2 > 5 wt% K 2 CO 3 /0.05 mol/L H 2 O 2 > 5wt% K 2 CO 3 .
