Withstanding Corrosive Attack Of Dissolved Hydrofluoric Acid In HF-Catalyzed Alkylation


  • Reduce frequency of downtime resulting from failure of both heat exchanger channels in caustic solution heater.
  • Improve safety for nearby personnel and equipment.
  • Reduce steam consumption, conserve space.


A Tranter MAXCHANGER Mini-Welded Plate Heat Exchanger with Monel 400 alloy plates to replace the existing 10-ft-long (3-m) carbon steel shell & tube exchanger.


  • Saved space–length only one-third the length of the original shell and tube heat exchanger.
  • Reduced size and weight also reduced the materials cost of the high alloy exchanger.
  • Corrosion and leakage problems ceased.

A Tranter MAXCHANGER Mini-Welded Plate Heat Exchanger made completely of Monel 400 alloy, can withstand the corrosive attack of caustic and traces of HF as a caustic heater in HF-catalyzed alkylation.
MAXCHANGER Mini-Welded Plate Heat Exchanger
This MAXCHANGER Mini-Welded Plate Heat Exchanger, manufactured from Monel 400 alloy, serves reliably as a caustic heater.
