The coalescing separator is primarily designed for liquid-liquid separation. It contains two filter elements, namely: coalescing filter element and separation filter element. For example, in the oil dewatering system, after the oil flows into the coalescing separator, it first flows through the coalescing filter element, which filters out solid impurities, and coalesces extremely small water droplets into larger water droplets. Most of the coalesced water droplets can be separated from the oil by its own weight and settled in the water collection tank. Then the oil flows through the separation filter element, because the separation filter element has good lipophilicity and hydrophobicity, and then further separates the water, and the clean, water-free oil flows out of the coalescing separator.
Used in the oil-water separation system, the first is to separate the oil-water mixture, suspension solution, emulsion solution, etc. The application process of the coalescence separation filter element in the system is divided into: solid-liquid separation --- demulsification --- coalescence --- separation ---adsorption.
