Vacuum Process Optimization
Vane Liquid Collectors deliver precision liquid recovery in high-vapor/low-liquid environments (<5 m³/m²hr). Engineered vane blades capture entrained droplets with minimal pressure drop (<0.1 psi), directing flow to annular sumps while maintaining 40-75% open area for unrestricted vapor passage – essential for vacuum distillation, olefins cracking, and monomer purification.
Core Technology
| Feature | Technical Advantage |
|---|---|
| Angled Vane Array | 99% droplet capture at vapor velocities ≤5 m/s |
| Annular Sump Design | Zero-gradient liquid collection with ±2% level variation |
| Modular Construction | Integrated troughs for columns >3m diameter handling ≤50 m³/m²hr |
| Vendor-Integrated | Welded sumps require column manufacturer coordination |
(Validated performance: <0.5% entrainment at F-factors ≤3.0 Pa⁰·⁵)
