The influence of silica nanoparticles on hydrodynamics and mass transfer in spray liquid–liquid extraction column

Mass transfer into/from nanofluid drops in a spray liquid‐liquid extraction column

“…18 In the field of mass transfer in nanofluids, there are a few researches dealt with mass diffusion in nanofluids 10,12,[19][20][21][22][23][24][25] and more researches investigated the influence of nanoparticles on convective mass transfer. 13,15,16,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] Nevertheless, most researches on convective mass transfer in nanofluids are related to the gas absorption processes [26][27][28][29][30][31][32][33][34][35] and there have been limited attempts to use nanofluids in other popular separation processes such as liquid-liquid extraction. 13,[37][38][39][40][41]<...>…”

This process involves the separation of components of a homogeneous liquid by transferring them between contacting immiscible or partially miscible liquids.…”

“…Single drops measurements are not directly applicable to the spray liquid-liquid extraction (LLE) columns due to the interactions between the adjacent drops. In our previous article, 44 the influence of toluene-based hydrophobic SiO 2 nanofluids with different nanoparticle concentrations on mass transfer and hydrodynamics in a spray liquid-liquid extraction column was investigated. Also, the effects of dispersed phase drop sizes were evaluated making use of three different distributors with different hole diameters.…”

Experimental investigation of the effects of the hydrophilic silica nanoparticles on mass transfer and hydrodynamics of single drop extraction

“…Among these researches, few are devoted to applying nanoparticles to liquid-liquid extraction processes [12][13][14][15][16][17][18][19][20].…”

“…One of the most recently published study in this field is Ashrafmansouri and Nasr Esfahany's article [18] on the influence of hydrophobic silica nanoparticles on hydrodynamics and mass transfer of a spray liquid-liquid extraction column. The results demonstrated that hydrodynamic parameters were not found to be influenced significantly by silica nanoparticles, whereas maximum augmentation of 47% in overall mass transfer coefficient was observed making use of 0.001 vol.…”
