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.

We have supplied Incoloy 825 heat-exchanger tubes of 2″ x 2.6mm x 3m(manufactured to ASTM B163 UNS N08825) for the fabrication of a distillation-column reboiler’s tube pass. Design temperature: 110°C, design pressure: 0.8 MPa, flow media: HF. The facilities belong to a reputable aluminum fluoride producer, Gulf Fluor, located in Abu Dhabi, UAE.
