AB Among all physicochemical technologies commercially available to upgrade biogas to biomethane, chemicalscrubbing with carbonated solutions stand as an easy-to-scale technology. However, the regeneration of thesolvent via air-assisted CO2 stripping is highly energy-intensive, representing >80 % of the total process costs.This study proposes the use of innovative Taylor flow reactors to enhance the liquid-gas mass transfer of CO2 andtherefore lower the cost of regeneration of carbonated solutions. In this study, a 200-glass capillary Taylor flowreactor supporting unprecedented mass transfer coefficients (kLa) was tested for the first time for CO2 strippingfrom carbonated solutions. The Taylor flow reactor achieved kLa coefficients higher than 100 h-1 at an inorganicconcentration (IC) of 1000 mgC L-1, and kLa > 400 h-1 at an optimal gas superficial velocity of 0.30 m s-1.Moreover, increasing IC concentrations to 2000 and 3000 mgC L-1 resulted in a kLa increase of 250 % and 65 %,respectively, whilst no significant increase was recorded at an initial IC concentration of 4000 mgC L-1. Indeed,multicapillary Taylor flow reactors demonstrated a superior and competitive performance during CO2 strippingfrom carbonated solutions, representing a promising technology for solvent regeneration during biogasupgrading at industrial scale.
