Stainless Steel 304 316 Random Packing Pall Ring For SO2 Wet Scrubber
Description of Random Packing
Metal random packing raschig ring is a fixed geometry of the bulk packing. Its simple shape, height and diameter of the same size. metal raschig ring is widely used in many areas. Metal raschig ring can be a variety of materials, such as carbon steel, stainless steel 304,304 L, 410,316,316 L, etc. to choose from. Metal raschig rings is made of material like carbon steel, stainless steel or Aluminum alloy, etc. The product has features such as thin wall, heat resistant, high free volume, high capacity, low resistance, high separation efficiency and so on. It is especially suitable for rectification towers under vacuum to treat thermosensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.

Applications of Random Packing
1. Distillation Columns
Used in petroleum refining, chemical processing, and solvent recovery systems to enhance vapor–liquid contact and improve separation efficiency.
2. Gas Absorption Towers
Applied in scrubbers to remove contaminants such as SO₂, CO₂, H₂S, ammonia, and VOCs from industrial exhaust streams.
3. Stripping and Desorption Units
Used in wastewater treatment and chemical plants for stripping dissolved gases (e.g., oxygen, nitrogen, CO₂) from liquids.
4. Air Pollution Control Systems
Installed in wet scrubbers and absorption reactors to increase gas–liquid interaction and improve pollutant removal efficiency.
5. Heat Recovery and Cooling Towers
Random packing enhances heat and mass transfer performance in cooling towers, gas cooling sections, and heat recovery units.
6. Water and Wastewater Treatment
Used in biological trickling filters, biofilm reactors, and aeration systems to provide effective support surfaces for microbial growth.
7. Chemical and Petrochemical Processing
Ideal for reactors and contactors where improved liquid distribution and reduced pressure drop are required.
