Product Description

Metal Pall Ring: Technical Overview and Applications

Metal Pall ring packing is an advanced structured packing developed from the Raschig ring, offering significant improvements in efficiency and performance. Below is a detailed breakdown of its features and applications:

1. Structural Characteristics
Material: Made from metal sheets (e.g., stainless steel, carbon steel) for durability and corrosion resistance.
Design:Features two rows of window holes on the ring wall, each with five protruding tongue blades bent inward toward the center.
The tongue blades enhance turbulence and gas-liquid contact, improving mass transfer efficiency while maintaining low pressure drop.
Advantages Over Raschig Rings:Higher surface area-to-volume ratio.
Reduced back-mixing and channeling due to optimized internal geometry.

2. Key Applications
Separation & Absorption:Used in distillation columns, absorbers, and strippers for processes like ethylbenzene separation, isooctane production, and vacuum distillation.
Environmental Protection:Desulfurization systems: Removes SO₂ from flue gases.
Wastewater treatment: Facilitates VOC (volatile organic compound)

3. Industrial Applications

(1) Petrochemical & Fertilizers

Synthetic ammonia decarbonization (high mass transfer efficiency).

Ethylbenzene separation (corrosion-resistant stainless steel variants).

Vacuum distillation systems (low pressure drop).

(2) Energy & Environmental Protection

Air separation units (ASU) & air cooling towers (optimized gas flow).

Atmospheric & vacuum distillation (thermal stability).

(3) Special Applications

High-temperature processes (up to 500°C).

Corrosive & heat-sensitive materials (316L for acidic/alkaline media).

4. Selection Guidelines

Requirement	Recommended Size	Material Choice
High mass transfer	16mm or 25mm	SS 316L(corrosion-resistant)
Low pressure drop	50mm or larger	Carbon steel(cost-effective)
High-temperature use	25mm or 50mm	SS 321(heat-resistant)
