Efficient separation of liquid-liquid mixture based on dispersion is often required in many industrial processes. Influence of mixing time, initial height of dispersion, mixing intensity and oil phase ratio on the separation time in liquid-liquid batch settler/separator were investigated in terms of coalescence and sedimentation profile. Experiments were carried out with oil in water type dispersion. Results showed that in most of cases coalescence controls the time of separation. The experiment results of liquid-liquid separation profiles were compared with the predefined model. MATLAB was used for the fitting of coalescence profile and calculating fitting constants. The data obtained from the batch experiments along with the mathematical model can be used as a good monitoring tool for studying the liquid-liquid dispersion behaviour in industrial units.
