 Pall   Ring

        Pall ring is one of the most common and well known packings, AceChemPack  is the top leading pall ring manufacturer, pall ring supplier. AceChemPack supply: metal pall ring, improved metal pall ring, plastic pall ring, ceramic pall ring plastic, pall ring and other column packings.

Improved Metal Pall Ring 

           AceChemPack Improved Metal Pall Ring (Similar to but Not Norton Hy-Pak) is an excellent improvment of the traditional Pall rings and is considered to be the most efficient ring type packing. At almost the same efficiency,  Improved Metal Pall Ring gives lower pressure drop than pall ring.  Improved Metal Pall Ring also increases the interfacial area available for gas-liquid contact. Its unique design incorporates strength enforcing ribs that allow for lower thickness for taller beds thus reducing procurement costs while replacing Pall rings with the same.

Metal  Pall  Ring  

         Metal Pall ring is one of the most common and well known packings, AceChemPack Metal Pall Ring is an industry standard design media developed from the Raschig Ring and is used widely in all variety of applications.  By minimizing the number of contours and crevices that can cause liquid hold-up and potential entrainment, the AceChemPack Metal pall ring geometry enables high gas and liquid transfer rates. The opened cylinder walls and inward bent protrusions of the AceChemPack Metal pall Ring allow greater capacity and lower pressure drop than standard cylindrical rings. This open ring design also maintains an even distribution and resists wall-channeling tendencies. The interior and exterior contacting surfaces of the AceChemPack Metal pall ring provide for an effective distribution of liquids and gasses and resist plugging, fouling and nesting. Pall rings are available in a wide range of materials.

Metal Pall Ring Features:

     Capacity vs Pressure Drop of AceChemPack Metal Pall Ring Packing, High loading & throughput / low pressure drop, Good liquid / gas distribution and high mass transfer efficiency.
         Versatility, Easily wettable, High resistance to fouling, High Temperature.
         Mechanical Strength of AceChemPack Metal Pall Ring Packing, High temperature applications, Mechanically robust, lesser probability of breakage, suitable for deeper beds.

Metal Pall Ring Application:  

         AceChemPack Metal Pall Ring Packing is widely used in All kinds of separation, absorb plants, constant decompress plants, compounding ammonia plant, decarbonization , desulfuration ,separation of ethylbenzene, separation of isooctane/ methylbenzene, Absorption, Aeration, Degassing, Desorption, Distillation, Stripping, Heat Recovery, Extraction, Various separation and absorption applications at atmospheric pressure and under vacuum, where a low pressure drop is critical,H2S, NH3 & SO2 Absorption & Stripping, Steam Stripping, Quench towers, Direct contact cooling.

• Absorption        • Aeration          • Degassing             • Desorption
• Distillation         • Stripping          • Heat Recovery      • Extraction

Ceramic  Pall  Ring

     Ceramic pall rings are originated  through improvement of raschig ring. Their open structures effectuate  separation of gas  and liquid streams and  thus facilitate a more effective mass  transfer. And decrease the pressure  drop. AceChemPack is the top leading manufacturer, supplier, exporter for ceramic pall ring column packing.


Plastic  Pall  Ring

       AceChemPack Plastic Pall ring has an advance on the Raschig Ring, the Pall Ring has similar cylindrical dimensions but has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop. AceChemPack is the top leading manufacturer supplier of plastic pall ring , plastic column packing.
       Capacity versus Pressure Drop of AceChemPack Plastic Pall ring, Most suited in low pressure drop, high capacity applications, A range of sizes of AceChemPack Plastic Pall rings allows the tower to operate at an optimum efficiency and throughput, Consistent ratio of free and blocked passages, independent of orientation, Large surface area : volume ratio augments the rate of liquid film surface renewal to improve mass transfer. Hold-up and Two-phase Contact, Promotes highly efficient two-phase contact and distribution; A relatively high liquid hold-up promotes high absorption efficiencies, especially in cases where the reaction rates are slow; Uninterrupted and consistent passages for gas and liquid flow.
       Versatility of AceChemPack Plastic Pall ring, Open, cross-linked design provides a highly efficient used of the ring’s surface area,Robust to variations in liquid and vapour distribution.

        Mechanical Strength of AceChemPack Plastic Pall ring, Its internal cross-structure of diametrical spars make it mechanically robust and suitable for use in deep packed beds.


       AceChemPack Plastic Pall rings are widely used in Absorption, scrubbing, and stripping services, Versatile alternative to metal Pall rings, all kind of separation,  constant decompress tower plants, compounding ammonia plant, decarbonization plant, separation of ethylbenzene,  seperation of isooctane/ methylbenzene.


Good Capacity and Low Pressure Drop  

  • Higher capacity and lower pressure drop than ceramic packing.

  • Multiple sizes provide ability to optimize capacity and efficiency based on application requirements. 

Higher Liquid Hold-up and Residence Time

  • Relatively high liquid hold-up allows good absorption efficiency with slow chemical reaction.

Versatile Standard Packing

  • Lower sensitivity to liquid and vapor distribution quality allows use with conventional liquid distributors.

High Mechanical Strength  

  • Ring and spoke construction provides high mechanical strength, which allows use in deep beds.

Material: polypropylene, strengthens polypropylene, strengthen nylon6, strengthen PBT
