Effect of channel size on mass transfer during liquid–liquid plug flow in small scale extractors

Biodiesel production in a serpentine minireactor—Effect of flow distribution

“…Similar observation is also reported in literature. 37 • Therefore, it can be concluded that at higher U SO or lower molar ratio, flow regime plays an important role in determining the FAME yield in R1. • Slug droplet being unstable regime shows fluctuations in FAME yield depending on predominance of long slug structure or dispersed drops.…”

Liquid–liquid two-phase mass transfer in T-type micromixers with different junctions and cylindrical pits

“…By applying a mass balance over the entire microchannel and by assumption of constant KLa [7], KLa was calculated using the following equation [3,9,36,38]:…”

“…Micromixers were proposed to enhance the mass transfer characteristics of the two-phase flow because of characteristic dimension of micron scale and thereby increasing the specific interfacial areas of two phases [7]. Liquid-liquid extraction is one of the most focusing two-phase mass transfer processes that can be intensified in microchannels owing to short transport distance and high specific interfacial areas of two phases [8,9]. Flowing two immiscible fluids in a microchannel causes stretching, deforming and folding the interfacial area of two phases that causes more effective inter-phase mass transfer.…”

Hydrodynamics and Mass Transfer of Gas‐Liquid and Liquid‐Liquid Taylor Flow in Microchannels

“…Process equipment containing multiple small parallel channels has gained increasing attention within the past decades in industry and academia due to its potential to intensify processes by enhancing heat and mass transfer or by more precisely controlling contact times [3,11,12]. Several processes have been successfully realized such as chemical or biocatalytic reactions [3,[13][14][15][16][17][18], extractions [19,20], and absorptions [21].…”
