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.
