“…This is because single drop columns are simple to study, and their performance can be accurately and easily controlled. [126] the mass transfer rate up to 157% and 121% at ϕ = 0.002 wt%, respectively. While adding nanoparticles initially improved the mass transfer rate for ϕ < 0.002 wt%, a reduction in mass transfer occurred when the nanoparticle content was further increased; the rates even dropped below those of the initial no-nanoparticle conditions at ϕ ˃ 0.004 wt%.…”

“…Such studies have shown that increasing the temperature from 15 to 40 °C can significantly increase the mass transfer performance of extraction columns [124,125]. In another study, Saien and Zardoshti [126] investigated the influence of temperature on mean drop size in a single drop extraction column in the presence of Fe 3 O 4 nanoparticles. They found that increasing the temperature gradually decreased the mean drop size due to the reduction of interfacial tension.…”

Recently, the use of nanoparticles in extraction columns has gained increasing attention due to their potential to enhance mass transfer processes. Most of the reported work, however, has been concerned with mass transfer enhancement in gas-liquid systems in the presence of nanoparticles, while limited studies of liquid-liquid systems have been reported. Liquidliquid extraction is an extensively employed separation method that has taken on a substantial role in engineering and industrial applications for recovery processes. Therefore, the aim of this review article is to provide an overview of the state-of-the-art from the available literature on the effect of nanoparticles on the hydrodynamic behavior and mass transfer performance of liquid-liquid systems. Attention is also given to providing an understanding of the mechanisms responsible for the improvements in mass transfer with the use of nanoparticles. In the majority of studies, the presence of nanoparticles was found to be beneficial and to lead to improved mass transfer, although a few investigations reported a detrimental impact of nanoparticles. The literature does not clearly describe the conditions under which the addition of nanoparticles would be unfavorable. Moreover, the addition of nanoparticles always introduces potential drawbacks, such as sedimentation, accumulation, or clogging inside extraction columns, as well as the need to separate the nanoparticles at the outlets. These drawbacks have not been considered in the literature, limiting the practical employment of nanoparticles in this industry.

“…In terms of hydrodynamic behavior, a reduction in terminal velocity with addition of nanoparticles was observed in most cases. Influencing factors as types of nanoparticle [163,164], size distribution [168], addition amount [163][164][165][166][167][168][169] and their addition in continuous or disperse phase [166] were systematically investigated. For mass transfer investigation, it is interesting to find that mass transfer rate increased as more nanoparticles were added.…”

“…It might be attributed to Brownian motion of nanoparticles and subsequent micro-convection or aggregation and clustering of nanoparticles [169]. Other factors as temperature [165] and in presence of magnetic field [167] were taken into consideration. For the purpose of industrial use, a great deal of work remains to be done concerning simulation or downstream separation process for recycling the nanoparticles as well as solvent.…”

“…In both these methods, acetic acid must be separated from dilute aqueous solutions. Because the separation of acetic acid by a distillation process is quite difficult and expensive, the liquid–liquid extraction process can be used by means of an appropriate organic solvent. − Toluene can be chosen as an appropriate solvent due to low vapor pressure, viscosity, and density, and its capability to form two distinct phases at ambient conditions. , Moreover, in recent years, there has been growing interest in the literature to use the ternary system of toluene–acetic acid–water (TAW). − Most of these studies have been conducted in the fields of transport and interfacial phenomena.…”

Liquid–Liquid Equilibrium Data, Density, Viscosity, and Interfacial Tension of Ternary System (Toluene–Acetic Acid–Water) at 298.15 K: Experiment and Correlation

Liquid−liquid equilibrium (LLE) data, density, viscosity, and interfacial tension for the ternary system of toluene−acetic acid− water were measured at 298.15 K and 101.7 kPa. The Othmer−Tobias and the Hand correlations were used to check the reliability of the experimental tie-lines. Moreover, the distribution coefficient and the separation factor were explored. It was found from the experimental results that a maximum separation factor value happens at an acetic acid mass fraction of 0.02 in the organic phase. Density, viscosity, and interfacial tension were correlated using the appropriate correlations such that the predicted results have excellent agreement with the experimental data. The experimental data in this work and the literature were correlated using both the nonrandom two-liquid (NRTL) and the universal quasi chemical (UNIQUAC) activity coefficient models at various temperatures (288.2, 298.15, 303.15, and 313.15 K). The experimental results were used to obtain binary interaction parameters in these models. The root-mean-square deviation (RMSD) values for both models were less than 3.58%, and the model predictions show acceptable agreement with the measured data particularly at the plait point.
