METAL PALL RING PACKING 
Pall Ring Introduction: Pall rings are one of the commonly used tower packing. It is widely used in high-volume high-temperature processes such as distillation towers, absorption towers and scrubber towers. It is versatile and economical.The invention of the Pall ring packing greatly improved previous packing methods so much, so that it is still considered one of the most effective packing methods today. As a leading supplier of random tower packing, Super Packing Mall Engineering manufactures plastic, ceramic and metal pall rings for industrial use. Our products combine excellent quality with an reasonable price and we will provide customers with all technical service support. Pall Rings vs. Raschig Rings Raschig rings are cylindrical tubes that have equal height and diameter. They're typically made of metal plastic or ceramic. When used for distillation, vapor will condense on the ring's surfaces. While the vapor and liquid pass each other in the small space, they try to achieve equilibrium. As a result, the material that is harder to evaporate goes downward in the tube, and the easily evaporable material goes upward. The Raschig ring is considered the first generation of ring packing, and since its invention, the ring design has been altered to be more efficient and handle higher capacities. Pall ring was a significant advancement for random packing. Pall rings are similar to Raschig rings in that they have equal height and diameter. The significant difference between the two is that pall rings have windows and tabs punched in the walls. Most commonly pall rings are made of metal, ceramic or plastic, depending on the conditions of the application. Adding the windows and tabs increased the capacity and efficiency of the ring significantly, as the gas and liquid distribution is improved. The tabs being folded into the center of the tube creates drop points, allowing more internal surface area to be used. This improved packing design is flexible, has low resistance and high separation capabilities. Application： 1) ethylene extraction columns; 2) mass-tranfer columns separation devices; 3) carbon dioxide and hydrogen sulphide absorbers and flash tower; 4) liquid extractors; 5) carbon monoxide converters; 6) dimethyl terephthalate running column; 7) NH3 extraction devices; 8) petrochemical and medical equipment.
