Product Description of Metal Pall Packing
The metal pall ring packing was developed in the 1940s by the German company BASF and is made of sheet metal with a total area of about 35% of the total area of the ring wall.Compared with the same specifications of the raschig ring packing, because of pall ring packing opened many hole in the ring wall, makes the tower of gas and liquid can be free from the window by, so packing layer of gas and liquid distribution than raschig ring packings have greatly improved, its separation performance, help pall ring filler is still currently adopted one of the main ring packing.

Features of Metal Pall Packing
1. High Mechanical Strength & Mechanically Robust
Pall Rings are manufactured from robust materials such as metal, plastic, or ceramic. The strategic inclusion of windows and internal struts within the design creates a structure that is both lightweight and exceptionally strong. This provides high mechanical strength, making them resistant to crushing under the weight of the packed bed and ensuring a lower probability of breakage during handling, installation, and operation, even in tall columns.
2. High Capacity with Low Pressure Drop
The open window design is fundamental to their performance. It provides open pathways for gas and liquid to flow through the packing bed with minimal restriction, effectively eliminating the "wall flow" effect and channeling common in solid fillers. This results in a significantly lower pressure drop compared to earlier generations of packing, which allows for higher vapor and liquid flow rates (high capacity) and reduces energy consumption in the system.
3. Good Liquid/Gas Distribution and High Mass Transfer Efficiency
The tongues on the ring walls serve to deflect and spread liquid across the packing, breaking it into finer films and droplets. Simultaneously, the windows disrupt and redistribute the gas flow continuously. This creates excellent interfacial contact between the phases, promotes intense mixing, and ensures good distribution across the column's cross-section. The combined effect is a high surface area for contact and high mass transfer efficiency.
4. Easily Wettable and High Resistance to Fouling
The large and accessible surface area, combined with the liquid-dispersing tongues, promotes excellent wettability, even at lower liquid rates. Furthermore, the open structure prevents solids from building up and allows for the passage of polymeric materials that might cause blockages in other packings. This leads to a high resistance to fouling, extending operational run times between maintenance cycles.
5. High Temperature Endurable for High Temperature Applications
Depending on the material of construction, Pall Rings can endure a wide range of temperatures. Ceramic Pall Rings are ideal for extremely high-temperature and corrosive service, while metal alloys (e.g., stainless steel) offer strength and durability in demanding high-heat applications within petrochemical processing. This makes them suitable for a vast array of high-temperature applications.
In summary, Random Pall Rings are a premier choice for engineers seeking a robust, efficient, and reliable packing solution. Their balanced combination of high strength, low pressure drop, excellent efficiency, and fouling resistance makes them a go-to option for revamping existing towers or designing new processes for optimal performance.
