CO2 absorption characteristics of nanoparticle suspensions in methanol

CO2 absorption/regeneration enhancement in DI water with suspended nanoparticles for energy conversion application

“…Therefore, the absorption performance is decreases by the increase of viscosity at high concentration of nanoparticles. In addition, if the particle concentration increases over a critical value, it causes a reduction of the Brownian motion, because the inter-particle interaction hinders its motion [30]. Fig.…”

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

“…In each section, performed studies, type of nanofluids, size and concentration range of nanoparticles, mass transfer measurement method, maximum observed enhancement and suggested mass transport mechanisms were pointed out [13]. In the field of mass transfer in nanofluids, there are a few researches dealt with mass diffusion in nanofluids [1,9,[14][15][16][17][18][19][20] and more researches investigated the influence of nanoparticles on convective mass transfer [10,[21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Nevertheless, most researches on convective mass transfer in nanofluids are related to the gas absorption processes [21][22][23][24][25][26][27][28][29][30] and there have been limited attempts to use nanofluids in other popular separation processes such as liquid-liquid extraction [10,[34][35][36]…”

Experimental investigation of benzoic acid diffusion coefficient in γ-Al2O3 nanofluids at different temperatures

“…Uncertainty in the ith independent variable [9][10][11][12][13]. In the case of gas absorption process in nanofluids, most of the researchers have shown that nanoparticles can promote mass transfer coefficient [14][15][16][17][18][19][20]. Although a few studies showed that the mass transport rate in nanofluids is decreased, this can be enhanced with increasing the volume fraction of nanoparticles [21,22].…”
