Random Packing - Metal, Plastic and Ceramic Materials

Random packing is widely used in the packing towers for gas and liquid, separating, absorbing, cooling and other applications. Random packing has different types with the materials and structure improvement. Here are some main types of random packing, just refer to them and find the perfect one you need.

Raschig Ring

Raschig ring is the simplest structure of all types of random packing. The diameter size is same as the height, which is similar to the pall ring. The large size which the diameter is larger than 100 mm Raschig ring is commonly filled neatly when using, but the smaller size which the diameter is smaller than 75 mm is commonly filled in huddle.

Raschig ring can be made of metal, ceramic and plastic. The structure of metal Raschig ring is similar as the ceramic pall ring, which has smooth cylinder wall and simplest structure.

Pall Ring

Pall ring is the improved products of Raschig ring. Compared with Raschig ring, the features of pall ring is the diameter size is same as the height. Besides, there are two layers of window on the cylinder wall. And each wall have five ligules bending inward. The structure may different according to the material and diameters.

The openings on the cylinder wall let the pall ring make full use of the inner surface and improve the separating and absorbing efficiency. The flux of pall ring improves 50% than the Raschig ring but the pressure drop reduce half.

The material of pall ring is commonly metal, plastic and ceramic. Metal pall ring can be stainless steel, carbon steel and other alloy steel. They have outstanding corrosion and rust resistance performance in the chemical and other harsh using environments. The plastic pall ring has outstanding temperature resistance, it can remain perfect condition no matter in the subzero or high temperature environments. The ceramic pall ring has thicker thickness than the metal or plastic pall ring. It may has high absorbing efficiency in all conditions.

Intalox Saddle Ring

Intalox saddle ring, as its name says, the shape is similar to the saddle, but its shapes is between the ring and saddle. This design make full use of the advantage of ring and saddle. It can not only benefit for the liquid distribution, it can also improve the flux of gas. Compared with pall ring, it has larger flux, less resistance and higher efficiency. Additional, it has high rigid and mechanical strength, it is the most widely used type among all the random packing.

The material of intalox saddle ring can also be stainless, plastic and ceramic. Intalox saddle ring is mainly used in the drying towers, absorption tower, cooling tower, washing tower and regeneration tower of chemical, metallurgy, coal gas and environmental protection industries.

Cascade Mini Ring

The cascade mini ring is the advanced product of pall ring. The feature of cascade mini ring is the ratio of height and diameter is 1:2, and cone-shaped flange is added onto the end of the Cascade mini ring. It can not only improve the mechanical strength, it can also reduce the gas passing resistance and increase the flux. Additional, the liquid and gas has uniform distribution and then the separating efficiency is improves through increasing the contact area.

Cascade mini ring can also be made of metal, plastic and ceramic materials. And the structure of cascade mini ring may different according to different materials and diameters.

Cascade mini ring is widely used in the packed towers in petroleum, chemical, chlor-alkali, coal gas, environmental protection and other industries.

Features of random packing

• High flux.
• Low pressure drop.
• Low resistance.
• High efficiency.
• Different sizes to satisfy different applications and efficiency requirements.
• Various materials to be used in different environments.
• Ceramic random packing has outstanding acid resistance and temperature resistance. It ca resist all the organic acid, inorganic and organic solvents except the hydrochloric acid.

Applications of Random packing
Random packing is widely used in the chemical, metallurgy, coal gas, environmental protection industries for gas and liquid separations in dying towers, absorption towers, cooling towers, washing towers and regeneration towers.
