Hydrocyclones have the advantages of fast separation speed, simple structure, small footprint, and convenient operation/maintenance, resulting in satisfactory performance wide applications. However, conventional hydrocyclones are incapable separating fine particles or droplets. A hydrocyclone with media-size redistribution (HMSR) was designed studied to alleviate this shortcoming. The overall efficiency could be improved by design. Based on theory analysis numerical simulation, mechanism...
Oil is one of the world's most crucial energy sources. In recent years, separation hydrocyclones coupled with multiphase or multifield has emerged as a leading trend in oilfield-produced fluid pre-separation technology. The study complex dynamics among particles multiphase-coupled systems. this paper, we explore novel approach: hydrocyclone to enhance oil–water separation, based on composite force field. computational dynamics-discrete element method utilized analyze dynamic behavior and oil...
The main diameter of hydrocyclone (HC) has significant effects on separation performance. However, the differences flow field characteristics within different HCs have not been understood well yet, which makes it impossible to grasp influence mechanism Through study migration trajectories particles, is found that greater and finer more particles escape from overflow outlet. relationships between longest residence time HC for with 10 15 μm were, respectively, clarified. high-speed video...
The special dynamic hydrocyclone for the thin oil dewatering is developed combining with its advantage in creating high strength swirl field, aiming at character of oil. By lab experiment, curves, between input water cut, viscosity, speed rotating wall, ratio and efficiency, are obtained. Then, operating parameters optimized specified construction. Subsequently, one process series/parallel connection several hydrocyclones designed. result experiments shows that applying can lessen cut to...
