AB  - Separation of oil in water emulsion is very challenging issue, especially, in industrial applications.
Two identical hydrocyclones are designed and used to separate oil (kerosene) from oil in water emulsion. The
operational variables such as split ratio (0.1-0.9), feed flow rate (6-12 L/min) and inlet oil concentration
(250-1250 ppm) as well as the design parameters such as vortex finder length (0.6-2.7 cm) are investigated for
single and double hydrocyclones. It was shown that the separation efficiency is enhanced by connecting two
hydrocyclones in series. The optimum conditions were estimated using Minitab program with 2<sup>3</sup> factorial design
of experiments. It was shown that optimum feed flow rate Q<sub>i</sub> = 12 L/min, inlet oil concentration C<sub>i</sub> = 250 ppm, split 
ratio F = 0.9 and VFL = 1.3 cm gave maximum obtainable separation Efficiency (E<sub>j</sub> = 94.78%) and minimum
Pressure Drop Ratio (PDR = 0.895) for single hydrocyclone. This efficiency increased to 95.2% and PDR
decreased to 0.86 by using two hydrocyclones.
