What is a pall ring used for?

Pall Rings are primarily used in packed towers for the following applications:

  1. Gas Absorption

    • Removing impurities or specific components from gas streams (e.g., CO₂, H₂S, SO₂ removal in flue gas desulfurization).
    • Example: Scrubbing acidic gases in chemical plants.
  2. Distillation

    • Separating liquid mixtures based on their boiling points (e.g., in the petrochemical industry for refining crude oil).
  3. Stripping

    • Removing volatile components from liquids (e.g., stripping ammonia from wastewater).
  4. Heat Transfer

    • Serving as a medium in cooling towers or heat exchangers to improve heat transfer efficiency.
  5. Chemical Reactions

    • Enhancing contact between reactants in catalytic or reactive distillation processes.
