The coalescing separator is mainly designed for oil-water separation, and it contains two kinds of filter elements, namely coalescing filter element and separation filter element.
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 their own weight and settle into the sump.
Then the oil product flows through the separation filter element, because the separation filter element has good lipophilicity and hydrophobicity, so as to further separate the water, and the clean and water-free oil product flows out of the coalescence separator.
