Key Features
- Packed or Tray Columns: FRP columns with random packing or trays resistant to chemical attack.
- Vapor/Liquid Inlet Nozzles: Corrosion-resistant flanged connections for feeds and off-gas.
- Condensate Collection: FRP sumps or traps for any condensed liquids.
Benefits
- Eliminate Corrosion: FRP resists hot, corrosive vapors that would ruin metal columns.
- Compact Footprint: High surface-area packing achieves efficient stripping in shorter columns.
Applications
- Fume Treatment: HCl stripping from spent pickling acid, NH₃ stripping from wastewater.
- Chemical Production: Recovery of chemicals by steam stripping.
Technical Specifications
- Height: Ranges from 5 to 20 meters.
- Diameter: From 0.5 to 2 meters.
- Media: Steam or air stripping; vessels are gas-tight.
Unique Selling Points
- Proven with Acid Gases: FRP columns widely used in acid regeneration (e.g., HCl recovery) processes.
