The various methods for the separation of finely dispersed oil-water suspension have been studied accordion to the types of emulsion. In the present study, the demulisification of a toluene-water suspension system was examined by using porous alumina as an adsorbent. Dispersions were generated by supersonic wave treatment, and the harmonic average diameter of droplets was 1.3 μm. Sodium dodecylbenzenesulfonate was used for water-in-oil emulsion, and magnesium oleate was used for oil-in-water emulsion as surfactants. The concentration of the surfactants was ten times as much as the critical micell concentration. The separation was performed by passage through alumina beds, and by addition of alumina in emulsion. Since the demulsification was caused by the adsorption of surfactants on the alumina surface, the suspension with nonion type surfactants like as Span and / or Tween, which were not adsorbed on alumina could not separated. In the case of an anion type surfactant, however, both types of O/W and W/O emulsion could be separated. The separation ability which was diminished by the adsorption of the surfactants was partially reactivated by desorption treatment. |
