FRP Stripping Columns

FRP stripping columns remove volatile or toxic components from liquid streams by passing steam or gas counter-currently. FRP construction allows the use of strong acids or bases in the stripping liquid (e.g., hydrochloric acid stripping HCl gas).

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.
