摘要

Abstract

In this work

an air-blast atomizing column was used to study the CO

capture performance with aqueous MEA (mono-ethanol-amine) and NaOH solutions. The effects of gas flow rate

the liquid to gas ratio (L/G)

the CO

concentration on the CO

removal efficiency (

) and the volumetric overall mass transfer coefficient (

) were investigated. The air-blast atomizing column was also compared with the pressure spray tower on the studies of the CO

capture performance. For the aqueous MEA and NaOH solutions

the experimental results show that the

decreases with increasing gas flow rate and CO

concentration while it increases with increasing L/G. The effects on

are more complicated than those for

. When the CO

concentration is low (3 vol%)

increases with increasing gas flow rate while decreases with increasing L/G. However

when the CO

concentration is high (9.5 vol%)

as the gas flow rate and L/G increases

increases first and then decreases. The aqueous MEA solution achieves higher

and

than the aqueous NaOH solution. The air-blast atomizing column shows a good performance on CO

capture.
