Abstract

Phase inversion in liquid-liquid DISPERSIONs is a common phenomenon that occurs in many industrial processes. However, the mechanisms responsible for PHASE INVERSION and the effect of the physical and geometrical parameters on this phenomenon are not well understood. In this paper, the effect of agitation speed, type of chemical system and mineral salts on PHASE INVERSION behavior in batch-agitated vessels has been investigated. In order to study the PHASE INVERSION, a variable speed agitator and conductometer has been used. The results showed that with increasing agitation speed, the O/W DISPERSION invert at decreasing values of critical DISPERSED PHASE holdup, whereas W/O DISPERSIONs follow the reverse trend. Also, it is shown that decreasing interfacial tension of DISPERSION, shifts ambivalence limits downward and widening it. Also, addition of salt to water phase influenced PHASE INVERSION behaviour and facilitated the PHASE INVERSION of O/W DISPERSIONs and since the salt has higher ionic strength, its effect was higher.
