This article reports the first successful CO2 capture in a continuous oscillatory baffled reactor. Many operation variables and the effect of the constant baffle size and distance on CO2 capture were evaluated. The variables were the gas flow rate, solvent types (water, Monoethanolamine, Diethanolamine, and Triethylamine), and the existence of oscillation and baffling at constant residence times. Oscillations probably contributed to the increased growth in CO2 capture in the oscillating flow reactor. Furthermore, the mixing intensity resulted in a highly efficient and stable CO2 capture. In the results, oscillating flow reactors were proven to act as liquid–gas contactors capable of capturing CO2.
