Detailed explanation of the working principle and application of coalescing separator

In the process of petroleum refining or mechanical processing, since the raw materials themselves contain water (or water enters during the process), the medium will inevitably be mixed with moisture. The presence of moisture will affect the process effect, process equipment and product quality. Causes adverse effects, therefore, the coalescing separator plays a vital role.

The coalescing separator breaks through the single filtration mode of traditional filters and integrates filtration and dehydration. It can filter out various tiny particles, moisture, fibers and suspended matter in the fuel. It is an ideal oil purification equipment.

Product structure and working principle

The coalescing separator is mainly designed for liquid-liquid separation. It contains two types of filter elements, namely a coalescing filter element and a separation filter element. It is also equipped with accessories such as a drain valve, a drain valve, a differential pressure gauge, 

a safety valve, and a heat tracing device.

In the oil water removal system, after the oil flows into the coalescing separator, it first flows through the coalescing filter element to filter out solid impurities, and coalesces very small water droplets into larger water droplets. Most of the coalesced The water droplets can be separated from the oil by their own weight and settle into the water collection tank. Then the oil flows through the separation filter element. Since the separation filter element has good lipophilic and hydrophobic properties, the water is further separated. Finally, the clean and water-free oil flows out of the coalescing separator.
