Pall rings are a type of random packing used in chemical processing, petrochemical plants, and other industrial applications. They are designed to enhance the contact between gases and liquids, improving the efficiency of mass transfer processes.
Pall rings are cylindrical in shape with two layers of windows on the cylinder wall. Each layer has several ligules that are bent inward towards the axis of the ring. This unique design increases the surface area and void space within the packing, promoting better fluid distribution and gas-liquid contact.
Pall rings can be made from a variety of materials including plastic, ceramic, and metal, depending on the application requirements. The choice of material affects the ring’s chemical resistance, mechanical strength, and thermal stability.
