Key Features
- Tall Modular Sections: Sections bolted and sealed to form columns up to required height.
- Corrosion-Resistant: FRP shell plus protective liners (optional) handle corrosive vapors and condensates.
- Internal Trays/Packings: Corrosion-proof tray supports or random packing support structures.
Benefits
- Metal Replacement: FRP saves costs and maintenance where stainless steel would corrode.
- Thermal Stability: Good insulation properties reduce heat loss.
Applications
- Chemical Plants: Acid recovery towers, solvent distillation, petrochemical fractionation.
- Manufacturing: Sterilization columns in chlorine/dioxide plants.
Technical Specifications
- Height: Ranges from 5 to 25 meters (can be taller with field assembly).
- Diameter: From 0.5 to 3 meters (customized based on duty).
- Construction: FRP (vinyl ester) jacket with optional liners.
- Pressure Rating: Typically designed for slight vacuum up to a few bar (low pressure).
Unique Selling Points
- Custom Fabrication: Ability to build large-diameter, high columns on site.
- Integrated Solutions: Can include FRP condensers, reflux drums, and piping for complete distillation systems.
