The coalescing separator is mainly designed for liquid-liquid separation. It contains two kinds of filter elements, namely: poly 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 droplets.
Most of the coalesced water droplets can be separated from the oil by their own weight and settled in the water collection tank. Then the oil product flows through the separation filter element. Because the separation filter element has good lipophilicity and hydrophobicity, it further separates the moisture, and the clean, water-free oil product flows out of the coalescing separator.
Used in the oil-water separation system, mainly separated oil-water mixtures, suspension solutions, emulsion solutions, etc., the application process of the coalescence separation filter element in the system is divided into:
Solid-liquid separation --- demulsification --- coalescence --- separation --- adsorption.
