Natural Gas Coalescing Filter

The coalescing separation has a filter element with two different functions inside - a coalescing filter element and a separation filter element. When the oil flows through the coalescer, it undergoes four stages of filtration, coalescence, sedimentation and separation in its interior to realize the function of filtering out particulate pollutants and releasing moisture. The coalescing filter has the dual function of filtering impurities from the oil and agglomerating moisture, and is an important functional energy component of the filter separator. It meets the needs of various filter separators used in fixed and mobile fueling facilities....

In order to solve the problem of excessive water content in various oils, our company adopts the "coalescence separation" dehydration technology. It combines the functions of precision filtration and filtration to effectively remove particulate pollutants, emulsified water, dissolved water and free water in the oil. The filtration precision can reach NAS4-6 level, realize continuous operation and unattended, with pressure. The advantages of type, centrifugal and vacuum oil filters are unmatched.


How does the coalescing filter separation technology work properly?

1. Surfactant of filter element: The surface active substance is dispersed in the emulsion, which reduces the tendency of the droplets to coalesce because it reduces the interfacial tension of the oil-water system. Numerous tests have shown that the separation effect of different oil-water system filter elements is different. It has been experimentally tested that the presence of water-soluble surfactants reduces oil droplet coalescence; if oil-soluble surfactants are present in the dispersed phase, the droplet coalescence remains almost unchanged. Therefore, experts suggest that when selecting oil protection agents such as anti-corrosion agents, anti-yang agents, etc., different surfactants should be selected according to different oil-water systems.


2. Filler size: After many experiments, the smaller the size of the filler, the larger the specific surface area per unit mass, and the larger the contact area with the droplets, thus the performance is enhanced. Therefore, it is recommended that you consider the coalescing filter separation efficiency when considering the fiber size, and also consider the pressure drop problem.


3. Thickness of coalescence bed: The results show that as the thickness of the coalesced bed increases, the degree of coalescence increases correspondingly, and the pressure drop also increases, but when the critical value of a liquid is reached, the coalescence effect For no longer change. This indicates that the thickness of the coalescence bed is also related to the fiber reduction used.
