Key Features
- Spiral Structure: Creates a uniform helical liquid film for efficient gas-liquid contact.
- High Surface Area: Comparable to Pall Rings but often with even distribution patterns.
- High Voidage: Typical values ~94–96% for 50–100 mm sizes.
Benefits
- Excellent Efficiency: Spiral design enhances mixing with minimal resistance.
- Stable Performance: Firm interlocking prevents shifting under flow.
Applications
- Distillation/Absorption: Used where high throughput and efficiency are needed in limited column space.
- Heat and Mass Transfer Equipment: Wherever other random packings are used, Heilix can be an alternative.
Technical Specifications
- Sizes: E.g. 50–100 mm diameters, as in [76].
- Surface Area & Voidage: 50 mm size – 100 m²/m³, ~94% void.
Unique Selling Points (USPs)
- Proprietary Design: Less common, may offer performance advantages in niche processes.
- Low Pressure Drop: Helical paths support smooth flow even at high capacity.
