Gas–liquid mass transfer in a falling film microreactor (FFMR) with 29 microchannels (0.6
mm width each) was investigated. CO
2 was absorbed from a CO
2/N
2 gaseous mixture into a NaOH aqueous solution and the liquid-side mass transfer coefficient and the gas-side mass transfer coefficient were measured. The influence of gas concentration on the value of gas-side mass transfer coefficient has been discussed.
