investigation of mass transfer coefficient under jetting conditions in a liquid-liquid extraction system
نویسندگان
چکیده
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 height of the continuous phase above the nozzle, on mass transfer coefficient have been investigated. a correlation has also been derived in order to predict the mass transfer coefficient as a function of physical properties of both phases and aforementioned parameters. based on the experimental results, mass transfer coefficient increases with an increase in the nozzle diameter and jet velocity, while increasing the height of the continuous phase above the nozzle decreases the mass transfer coefficient. these results may reveal the importance of mass transfer during the jet formation and breakage.

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...
