Hydrodynamics in spray and packed liquid-liquid extraction columns: A review

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...

Troubleshooting Liquid-liquid Extraction Columns

Process engineers can be faced with the task of understanding and optimizing the performance of an existing liquid-liquid extraction (extraction) column. Often times, an extraction column has been operating many years, and the performance is not well understood by the personnel responsible for its operation. Since this technology is not treated comprehensively during most under-graduate Chemica...

Experimental Investigation of Phase Inversion of Liquid-Liquid Systems in a Spray Extraction Column

An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...
