Pall Rings are primarily used in packed towers for the following applications:
-
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.
-
Distillation
- Separating liquid mixtures based on their boiling points (e.g., in the petrochemical industry for refining crude oil).
-
Stripping
- Removing volatile components from liquids (e.g., stripping ammonia from wastewater).
-
Heat Transfer
- Serving as a medium in cooling towers or heat exchangers to improve heat transfer efficiency.
-
Chemical Reactions
- Enhancing contact between reactants in catalytic or reactive distillation processes.
- Enhancing contact between reactants in catalytic or reactive distillation processes.
