Devices for Continuous Generation of Dispersed Droplets

The extracted phenol concentration in water is near the equilibrium value for a wide range of total volume flow rates. Both mixers require a contact time of less than 1 s to reach the equilibrium concentration. 

Sprogies et al. compared micromixers for use in extractions based on emulsions [32]. They revealed that a multilamination mixer is more efficient than a simple T-junction, whereas a nozzle-type mixer and a split-and-recombine mixer show the best results for emulsification and thus for extraction.
