Incoloy 825 Tubes Used for Distillation Column Reboiler in AlF3 Production

 Home » News

The distillation column reboiler is widely utilized for the production of dry aluminum fluoride(AlF3). The hydrogen fluoride(HF) is passed through the distillation column and get rectified. Then it is re-vaporized in the reboiler for further processing. Due to the corrosive and hazardous properties, hydrogen fluoride(fluid/gas) shall be properly handled. Generally, the high-temperature corrosion resistant material Incoloy 825 is chosen for the fabrication of tube pass of the reboiler.
