Packings for corrosive systems

Solutions for demanding corrosive applications

In cases where corrosion is a main issue and metal packings are not an option, we can offer you structured packings made of carbon and of different thermoplastic materials.

Mellacarbon™ packing for corrosive systems
Main benefits
  • Excellent wettability, also in aqueous systems
  • High thermal stability
  • Small pressure drop per meter packed height
Main applications
  • HCI separation for production and for HCI recovery (typically in the production of polycarbonate)
  • MCA / DCA distillation
  • Production of phosphoric acid
  • Concentration of hydrofluoric acid
  • Separation of chlorophenols
  • SO2 absorbers
  • Flue gas cleaning columns
  • Sea water deaerators
Mellacarbon™

Mellacarbon™

Mellacarbon™ combines all the advantages of a structured gauze packing with the corrosion resistance of carbon.

Key characteristics

  • Best choice for corrosive applications
  • Combines all the advantages of a structured gauze packing with the corrosion resistance of carbon
  • Corrosion proof against caustic solutions, non oxidizing inorganic acids including hydrofluoric acid and carboxylic acids
  • Excellent wettability, also in aqueous systems
  • High thermal stability (> 400°C)

Mellapak™ and MellapakPlus™

Some Mellapak™ and MellapakPlus™ types are also available in different kinds of thermoplastics. Packings made of polypropylene (PP), post chlorinated polyvinylchloride (PVC-C), polyvinylidene difluoride (PVDF), Teflon® PFA and polyether ether ketone (PEEK) can be supplied.

Key characteristics

  • Large number of transfer units per meter, low HTU, depending on the system
  • Small pressure drop per meter packed height
  • Most economical load range up to F factor 4 √Pa
  • Maximum operating temperatures: approximately 110°C for polypropylene, approximately 150°C for PVDF
