“…On the contrary, the past researchers working on mass and heat transfer during gasliquid flow (Yue et al, 2007;Vandu et al, 2005;Brauner and Maron, 1992;Gruber and Melin, 2003) have revealed a close link between transport properties and flow distribution and reported process intensification in slug flow microreactors. Further, the majority of the studies on liquid-liquid flow are confined to microchannels and not much is known about flow through capillaries with inner diameter in the order of millimetres.…”

Dedicated to Professor Rüdiger Lange on the occasion of his 65th birthday Hydrodynamics and mass transfer of both gas-liquid and liquid-liquid Taylor flow simulation in microchannels are reviewed. Theoretical approaches for description of hydrodynamic parameters and mass transfer characteristics are corroborated by comparison with available experimental results. Similarities and peculiarities of liquid-liquid flows versus gas-liquid Taylor flows in capillaries are discussed. Tools of mass transfer intensification of gas-liquid and liquid-liquid Taylor flow in microchannels are analyzed and optimal process conditions for gas-liquid Taylor flows are evaluated.

“…Several process intensification techniques proposed for enhanced transport characteristics attempt to optimize capital, energy, environmental and safety benefits. These include use of passive mixers which is already established for large diameters conduits [1], miniaturised devices (micro and milli) for enhancing the surface area available for mass transfer [2][3][4][5][6], use of ultrasound and vibration for inducing high mass transfer rates [7][8][9][10][11][12][13] and use of supercritical solvents [14][15]. There are also, several other options that are not mentioned here.…”
