Investigation of Packing Effect on Mass Transfer Coefficient in a Single Drop Liquid Extraction Column

Numerical simulation of the Marangoni e#ect on mass transfer to single slowly moving drops in the liquid–liquid system

The Marangoni e#ect is a frequently observed phenomenon of enhancement of interphase mass transfer in liquid–liquid systems. Such an e#ect, originating from the hydrodynamic instability induced by surface tension sensitivity to surface concentration of transferred solute, is mathematically formulated and numerically simulated for slowly moving single spherical drops in an axisymmetric boundary-...

Investigation of Mass Transfer Coefficient under Jetting Conditions in a Liquid-Liquid Extraction System

In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...

Investigation of mass transfer coefficients in irregular packed liquid-liquid extraction columns in the presence of various nanoparticles

In the present study, the effect of various nanofluids on mass transfer coefficients in an irregular packed liquid-liquid extraction column was investigated. The chemical system of toluene–acetic acid–water was used. 10 nm SiO2, TiO2 and ZrO2 nanoparticles with various concentrations were dispersed in toluene-acid acetic to provide nanofluids. The influence of concentration and hydrophobicity/h...
