Abstract

Process characteristics of CO

absorption using aqueous monoethanolamine(MEA) in a microchannel reactor were investigated experimentally in this work.A T-type rectangular microchannel with a hydraulic diameter of 408 μm was used.Operating parameters

i.e.temperature

pressure and molar ratio of MEA to CO

were studied.Under 3 MPa pressure

the mole fraction of CO

in gas phase could decrease from 32.3% to 300×10

-6

at least when gas hourly space velocity ranged from 14400 to 68600 h

-1

and molar ratio of MEA to CO

was kept at 2.2.In particular

the effects of temperature on CO

absorption flux

mass transfer driving force

gas-liquid contact time and enhancement factor were analyzed in detail and found that mass transfer enhancement by chemical reaction was a crucial factor for the process of CO

absorption.
