This paper reviewed the researches and applications of coalescence separation technique in oil/water separation, analyzed the basic process of coalescing separation and the factors influencing the coalescing separation efficiency. The principle of the three stages in the coalescence process： capture of the droplet, coalescence of the droplet and sedimentation of the droplet, were interpreted in detail. In addition, the effects of the fiber size and surface property, the velocity and other factors on the efficiency of the oil and water separation were analyzed. Finally, the existing problems in this field were summarized and development tendency of the coalescence separation technique was pointed out.
