Visualization study on oil-water separation phenomena in a liquid-liquid cylindrical cyclone (LLCC) separator

This study aims to understand the mechanism of oil-water separation process inside Liquid-Liquid Cylindrical Cyclone (LLCC) and the effect of operating parameters to the separation characteristics. Some experimental runs have been designed and commissioned, then the results from both experiments and visualization data are presented. General characteristics of separation process and flow behavior in the LLCC were explained in the form of qualitative observation and quantitative explanation. For the experimental runs, the LLCC was tested under the wide range of operating parameters such as inlet mixture velocity, split-ratio, and different inlet oil volumetric concentration. The acquired data includ e overflow oil volume fraction.
