What Is FiltEdge's Petrochemical High Flow Filter?
In the extreme working conditions of high temperature and high pressure in the petrochemical industry, ordinary filter elements are prone to blockage, shutdown, structural deformation, filter material damage, and decreased filtration accuracy when facing large particle impurities such as heavy oil and amine liquid, as well as strong acids, strong bases, and aromatic solvents. FiltEdge’s Petrochemical High Flow Filter is designed and manufactured to solve filtration problems in the petrochemical industry. It not only has an increased diameter of up to 6 inches in size, but its folding structure can handle large amounts of slurry for you while ensuring accuracy, which can reduce costs and increase efficiency in the petrochemical industry.
Why Does The Petrochemical Industry Use Petrochemical High Flow Filters?
In the face of extreme working conditions in the petrochemical industry, simply increasing the number of ordinary filter cartridges to expand the flow rate cannot achieve the desired effect. High flow filtration is not simply about increasing the size, but a specially designed Petrochemical High Flow Filter that uses a folding structure to solve the following difficulties for you:
- Reduce blockage and downtime: A single Petrochemical High Flow Filter adopts a deep folding structure inside, doubling the filtering area. It can increase your pollutant holding capacity and prolong the service life of your filter element.
- Reduce operating energy consumption: The large diameter flow channel of the Petrochemical High Flow Filter can maintain low pressure drop in high flow processes, allowing you to reduce energy consumption and minimize the frequency of filter replacement.
- Shorten maintenance time: With the same flow rate, the number of high flow filter cartridges used doubles and decreases, greatly reducing the time for manual filter replacement and minimizing your downtime.
- Save initial investment: The accompanying filter housing has a smaller volume than conventional filters, which can save you on initial purchase costs.

There are two main reasons for this. Firstly, there is a sudden fluctuation in the upstream process, which leads to a sudden increase in impurities in a short period of time, exceeding the preset processing capacity of the Petrochemical High Flow Filter; Secondly, the accuracy and aperture gradient design during selection are unreasonable, and large particle impurities directly block the surface of the Petrochemical High Flow Filter, without fully utilizing the deep filtration structure of the upper filter element. Tell us about your working conditions, and we will help you analyze the problem in detail and come up with improvement plans.
In petrochemical applications, instantaneous pressure shock when opening pumps or valves can cause physical deformation of the filter element, rupture of the filter material, and penetration of impurities. FiltEdge’s Petrochemical High Flow Filter uses a high-strength thickened central support skeleton and outer protective mesh, allowing it to withstand pressure differentials of 0.35-0.4MPa and cope with such fluctuations. But we also do not recommend keeping the filtering system in a fluctuating state for a long time.
FiltEdge not only sells filter cartridges, but also provides fluid diagnostic services. Through your filter housing structure, operating pressure difference curve, downstream fluid purity, and other aspects, it can help you identify whether it is a problem with the Petrochemical High Flow Filter or a design issue with the filtration system.
