The model wascapable of reproducing droplet formation in dripping, narrowing andwidening jetting regimes, as well as complex phenomena such as satelliteand multi-cored droplet formation.• The model was not able to prevent the droplet coalescence in thecollection tube since the kinetics of adsorption of surfactants at fluid–fluidinterfaces was not taken into account, which should be furtherinvestigated.• Successfully Production of encapsulated CO2 solvent within a three phaseglass capillary microfluidic device via on-the-fly photo-inducedpolymerisation approach in less than 3 minutes.• Successfully production and characterisation of a highly selective CO2sorbent based on molecularly imprinting technology and oxalic acidtemplate using a combination of membrane emulsification and suspensionpolymerisation approach.Experimental apparatus for fixed-bed adsorption
