Ceramic Tower Random Packing 50mm Ceramic Pall Ring Distillation Column
Ceramic Pall Ring are the most common form of random packing. They are similar to lessing rings and were developed from the Raschig ring. Pall rings have similar cylindrical dimensions but has rows of windows which increase performance by increasing the surface area. They are suited for low pressure drop and high capacity applications. They have a degree of randomness and a relatively high liquid hold up, promoting a high absorption, especially when the rate of reaction is slow. The cross structure of the Pall ring makes it mechanically robust and suitable for use in deep packed beds.

Ceramic Pall Ring is improved from the ceramic Raschig Ring, Ceramic Pall Ring has add a design of open the holes for the weeks wall, this construction can improve the surface area and voidage, Ceramic Pall Ring makes porosity distributed even and improves the distribution of the fluid, greater capacity and lower pressure drop than ceramic rasching ring.
Ceramic Pall Ring with excellent acid resistance and heat resistance. They can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently their application ranges are very wide. Ceramic Pall Ring can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.
Advantages of Pall Rings
Enhanced Mass Transfer Efficiency: The open structure design of Pall rings increases the contact area between gases and liquids, thus enhancing mass transfer efficiency.
Low Pressure Drop: Compared to other types of packing, Pall rings have a lower pressure drop due to their unique design, which helps reduce operating costs.
High Operational Flexibility: Pall rings can effectively operate across a wide range of conditions, including different flow rates and temperatures.
High Void Fraction: The high void fraction of Pall rings promotes good gas-liquid distribution, reducing the risk of blockage and liquid hold-up.
Suitable for Various Materials: Pall rings can be made from different materials (such as plastic, metal, and ceramic) depending on the chemical and physical operating conditions.
Ease of Cleaning and Maintenance: The structure of Pall rings facilitates easy cleaning and replacement, helping to lower long-term maintenance costs.
