Abstract:
In many industrial processes involving liquid-liquid dispersions, the phenomenon ‎of phase inversion will be encountered. ‎
In this work, effect of speed of rotation or energy input in the range of 400 to 800 ‎rpm in a batch liquid-liquid system of toluene and water on phase inversion has been ‎investigated.It was also studied the presence of sodium chloride and magnesium ‎sulphate in the system.‎
‎ It was shown that the increase of energy input had more obvious effect on O/W ‎dispersion at lower values of holdup. Also, shown that the ambivalence region of ‎phase inversion curve was shifted down ward and became wider as a result of ‎decrease in interfacial tension. ‎
It was observed that inorganic salt used in this work in both single shape, enhanced ‎phase inversion for O/W dispersion. ‎
