Product Introduction
Coalescer Cartridge is a core functional component for fluid separation and purification, the key part of all coalescence separation equipment. It integrates precision filtration and micro-droplet coalescence core functions, intercepting solid particle impurities in the medium while gathering tiny immiscible liquid droplets into large ones for gravity separation. It is a universal and replaceable core part, widely matched with vertical/horizontal coalescers in petroleum, chemical, natural gas and other industries for deep medium purification.
Working principle
Preprocessing and interception
The outer layer of the Coalescer Cartridge is designed with a precision pre-filtration layer, made of gradient porous materials such as glass fiber and polypropylene melt-blown fiber. It can efficiently intercept solid impurities, suspended solids and fiber debris in the fluid according to the filtration precision requirement. This step avoids impurities covering the inner coalescence layer, prevents interference with the coalescence effect, and reduces the formation of stable emulsion by impurities, laying a foundation for subsequent micro-droplet demulsification and coalescence.
Coalescence process
After impurity removal, the fluid flows through the inner coalescence layer of the cartridge. Driven by fluid flow, tiny dispersed liquid droplets in the medium are adsorbed on the surface of the coalescence fiber by surface tension. Relying on the hydrophobic/oleophilic or oleophobic/hydrophilic selective wettability of the special coalescence material, the adsorbed micro-droplets stay on the fiber surface and continuously collide and merge with other droplets during the flow. The multi-layer gradient structure of the coalescence layer makes the droplets undergo repeated collision and coalescence in the layer-by-layer flow, with the particle size increasing step by step until forming large droplets that can be separated by gravity.
Separation and sedimentation
The large droplets formed by coalescence pass through the separation layer of the cartridge, which has opposite wettability to the coalescence layer. Through the difference of material surface properties, the large droplets are blocked and separated from the base medium, and then break away from the fluid flow under the action of gravity and density difference, settling to the liquid collection chamber of the matching coalescer equipment. The separated clean medium passes through the cartridge and flows out, completing the purification and separation process.
Structural composition
Coalescence layer
The core functional layer of the cartridge, made of high-performance glass fiber, polypropylene or composite fiber with selective wettability. The multi-layer gradient pore structure design ensures the full contact between fluid and coalescence material, realizing efficient adsorption and merging of micro-droplets, and is the key part for realizing droplet coalescence.
Separation layer
Closely connected with the coalescence layer, made of hydrophobic/oleophilic modified fiber materials with high air permeability and liquid blocking performance. It blocks the large coalesced droplets and prevents them from being carried back by the fluid, realizing the effective separation of two immiscible media, and ensuring the purification effect of the fluid.
Support skeleton
The internal reinforcing structure of the cartridge, made of stainless steel mesh or hard plastic with high strength and good corrosion resistance. It provides mechanical support for the coalescence layer and separation layer, prevents the cartridge from being deformed or damaged due to fluid pressure impact during operation, and ensures the structural stability of the cartridge under different working pressures.
End cover sealing component
Located at both ends of the cartridge, made of nitrile rubber, fluororubber or EPDM with good sealing performance and chemical resistance. It realizes the tight connection between the cartridge and the coalescer equipment, prevents the fluid from short-circuiting (bypassing the filter layer and coalescence layer directly), and ensures that all fluid passes through the functional layer of the cartridge for effective separation and purification.
Product type
Liquid-liquid Coalescer Cartridge
Specialized for the separation and purification of two immiscible liquid media, the core component of oil-water separation coalescers. It can effectively break the stable oil-water emulsion formed in petroleum processing and chemical production, gather tiny water droplets (or oil droplets) in the liquid into large droplets for separation, and remove water or organic oil pollutants in the medium. It is widely used in the dehydration of petroleum products such as aviation kerosene, diesel oil and lubricating oil, and the separation of chemical solvent emulsions, with common filtration precisions of 1μm, 3μm and 5μm.

FAQ (Top 5 Concerns of Customers)
1. What is the general service life of the Coalescer Cartridge?
The service life is mainly determined by the medium impurity content and working flow, generally 3-6 months under normal working conditions (medium solid content ≤10ppm, flow matching equipment design). For media with high impurity content, the service life is about 1-2 months, and regular monitoring of the pressure difference of the equipment is recommended to judge the replacement time.
2. How to select the suitable Coalescer Cartridge for the existing equipment?
The selection is based on three core factors: medium type (liquid-liquid/gas-liquid), equipment model and specification (cartridge outer diameter/length), and process requirements(filtration precision, working pressure/temperature). We can provide matching schemes according to your equipment brand, model and production process parameters, and support the customization of non-standard specifications.
3. What materials are the Coalescer Cartridges made of, and how to select them according to the medium?
The main materials are glass fiber, polypropylene (PP) and polytetrafluoroethylene (PTFE). Glass fiber is suitable for general oil-water separation and gas-liquid separation; PP is food-grade, suitable for food and beverage industry and aqueous medium; PTFE has strong corrosion resistance, suitable for acidic, alkaline and strong corrosive chemical media.
4. How to judge whether the Coalescer Cartridge needs to be replaced in time?
There are three obvious judgment criteria: ① The pressure difference at both ends of the cartridge exceeds the rated value (generally 0.15-0.2MPa); ② The purification effect is significantly reduced, and the water content/impurity content of the treated medium fails to meet the process requirements; ③ The cartridge is deformed, damaged or aged, and there is medium short-circuiting.
5. Can the Coalescer Cartridge be customized for special working conditions?
Yes, we support full-customized production for special working conditions, including non-standard specifications (outer diameter/length), special filtration precision (0.1-10μm), high-temperature and high-pressure resistant materials, and corrosion-resistant coating treatment. You only need to provide the specific process parameters and working condition requirements, and we will design and produce the matching products
