Metal Pall Rings: High-Performance Random Packing for Industrial Processes
Engineered to revolutionize mass transfer efficiency, Metal Pall Rings deliver unmatched vapor-liquid contact with minimal pressure drop in distillation, absorption, and scrubbing towers. Their patented structure outperforms traditional packings while reducing operational costs.
| Parameter | Specification |
|---|---|
| Materials | 304/316/L SS, Carbon Steel, Titanium, Aluminum, Hastelloy® |
| Size Range | DN 16 (⅝") to DN 150 (6") |
| Surface Area | 72-350 m²/m³ (size-dependent) |
| Void Fraction | 94-98% (highest in class) |
| Packing Density | 79-365 kg/m³ |
| Operating Temp. | -200°C to +650°C (SS316) |
| Pressure Drop | 40% lower vs. Raschig rings |
| HETP | 0.3-0.5 m (distillation) / 0.4-0.7 m (absorption) |
| Certifications | ASTM B366, ISO 9001:2015, EN 10204-3.1 |
Optimal Fluid Dynamics
Perforated side windows + internal cross-struts create turbulent flow, enhancing surface wetting.
Rolled edges prevent mechanical deformation & fouling.
Corrosion Resistance
316L SS for HCl/Cl2 scrubbers | Titanium for seawater applications | Hastelloy® for extreme acids.
Efficiency Metrics
1. 30% higher capacity than saddle packings
2. 50% longer service life (10+ years in aggressive media)
3. 15-20% reduction in tower height (low HETP)
