The gas–liquid two-phaseflow and mass transfer performance of CO2 absorption into 2-amino-2-methyl-1-propanol (AMP) with ethylene glycol (EG) non-aqueous solution in a microchannel wereinvestigated under different gas–liquid two-phaseflow rates and AMP concentrations. A new correlationwas proposed for accurately predicting the liquid side volumetric mass transfer coefficient by consideringthe enhancement factor. It was verified that the volumetric mass transfer coefficient of CO2 absorption inthe microchannel is obviously higher than that in the traditional macroscopic column. Therefore, withthe usage of microchannel for AMP-EG non-aqueous solution, both low energy consumption and highefficient absorption could be reached.
