PCHG-372 Natural Gas Coalescer Filter Element - Knowledge

working principle:

The material flows through the coalescence filter element from the inside out, first passing through the high-precision filtration layer. The solid particles are intercepted by multiple layers of filter materials, achieving the purpose of removing particle pollutants. At the same time, the removal of particle pollutants is beneficial to the subsequent demulsification and coalescence functions of the filter element. The filtered material then enters the demulsification and coalescence layer to break down impurities in the material. The demulsified liquid enters the coalescence layer, and the working mechanism of the coalescence layer is that small water droplets come into contact with fibers and adhere to them. Under the pushing force of the fluid, they move along the fibers and coalesce with other small water droplets at the intersection of the fibers to form larger water droplets.

Large water droplets are carried by the fluid to the outer surface of the filter element. Due to their higher density than hydrocarbons, they separate from liquid hydrocarbons under the action of gravity and settle in the collection tank at the bottom of the filter separator. The larger the coalesced water droplets, the better the oil-water separation effect.
