The potential of microfluidic reactors, small capillary channels, to intensify mass transfer processes has been proven extensively over the last decades. In essence, liquid-liquid processes can be conducted 10—100 times faster with 1—10% of the energy requirements. These improvements imply that the same extraction process can be conducted with only 1—5% of the solvent used
