Metal Pall Ring

Product No: TPU®-MPR

metal pall ring tower packing

Metal Pall ring is one of the most common and well known packing, Metal Pall Ring is an industry standard design media developed from the Raschig Rings 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 Metal pall ring geometry enables high gas and liquid transfer rates. The opened cylinder walls and inward bent protrusions of the 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 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.

Capacity vs Pressure Drop    

• High loading & throughput / low pressure drop;    
• Good liquid / gas distribution and high mass transfer efficiency.


• Easily wettable;    
• High resistance to fouling;    
• High Temperature.

Mechanical Strength     

• High temperature applications;     
• Mechanically robust, lesser probability of breakage, suitable for deeper beds.

Metal Pall Ring Application:          

Metal Pall Ring Packing is widely used in All kinds of separation, absorb plants, constant decompress plants, compounding ammonia plant, decarburization, de-sulfuration, separation of ethyl benzene, 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.
