Stability Of Emulsion

The selective separation of aromatics (benzene, toluene and p-xylene, BTX) from aliphatic (n-heptane) is investigated using simple permeation and facilitated transport emulsion liquid membrane mechanism. The separation performances, represented by the permeation rate and separation factor, are analyzed systematically by varying the operating parameters. One of the major obstacles to the application of emulsion liquid membranes to industrial separations is the stability of emulsion globules. In the present study, stability of emulsion liquid membrane is studied by varying different parameters e.g. surfactant and feed phase concentration, stirrer speed for emulsification. Dispersion destabilisation of emulsion is detected by Turbiscan. Effects of interfacial tension on internal droplets size and size distribution are also systematically investigated. Stable emulsions under optimal conditions are used for the separation of aromatics (BTX) from aliphatic (n-heptane) in a synthetic feed mixture.

Stability Of Emulsion

The purpose of this paper is to investigate the effect of osmotic pressure on the morphology of emulsion liquid membrane (ELM) by the visual way. The experimental results show that osmotic pressure has great effect on the globules of emulsion liquid membrane through water diffusion between two water phases. When under isotonic pressure, the water transport trend cannot be observed. When osmotic pressure is less than zero, water transfers from the internal phase to the external phase. But when osmotic pressure is larger than zero, water transports from the external phase to the internal phase first by diffusion, then water transports from the internal phase to the external phase by the coalescence. Therefore, it is possible to tailor osmotic pressure between two water phases to keep the stability of emulsion liquid membrane when ELM is used to separate some component.

High demand on batik fabric significantly increased wastewater volume from batik home industries. Copper, being used as mordanting agent, available in the highest concentration in industrial textile wastewater. Emulsion liquid membrane (ELM) is promising selective method to recover solute. Taylor-Couette column (TCC) was proposedtoextractcopperinsteadofusingconventionalreactorthatdisturbsemulsion stability. Experiment was done by varying volume ratio of emulsion to feed phase, carrier and internal phase concentration. Extraction efficiency of>98% was obtained at volume ratio of emulsion to feed phase of 1:5, carrier concentration of 4 wt. %, and internal phase concentration of 0.1 M, respectively
