Publication date: Available online 4 July 2016 Source:Perspectives in Science Author(s): R.P. Ugwekar, G.P. Lakhawat The present phenomenon i.e. enhancement of mass transfer Coefficient in liquid-liquid extraction operation is a complex one and it cannot be reasoned out by any logic based model, so it is find out by experimental data based model. The present investigation is focused on the behavior of nanofluid in the liquid−liquid extraction process. The chemical system of Toluene-acetic acid−water was used, and nanofluids containing 0.1%, 0.2% and 0.3% (V/V) of zinc oxide nanoparticles of size 48.79nm synthesized by Chemical precipitation method. Maximum enhancements in the rate of mass transfer of were achieved using about 0.3wt % zinc oxide based nanofluids; however, a decreasing variation was observed at higher concentrations. The effect of nonionic surfactants Rokanol K7 (500ppm) on mass transfer of the liquid-liquid extraction process was also investigated and it was observed that the mass transfer coefficient increases rapidly with surfactants under a varying speed of agitation but deteriorates at high concentration. The Formulation of Approximate generalised experimental data based model has been developed followed by interpretation and the quantitative analysis of the model. For the aim of modeling, the experimental results obtained from Liquid-Liquid extraction were validated with mathematical modeling for calculation of reliability of model.
