Hydrochloric Acid Regeneration process stands for total recovery of metal-free chloride solutions based on the pyrohydrolysis principle.
Pyrohydrolysis is the chemical conversion of metal salts using steam and oxygen at high temperatures. Operators not only recover hydrochloric acid in its free and bonded state, but also obtain high quality iron oxide, either as granules or fine powder.
Using the Spray Roaster ARP technology, at lower temperature oxide is obtained as powder with grain size of approx 30 µm and a specific surface of 3-5 m²/g.
Many years of experience provide Tenova Key Technologies with specialized know-how in spray roast technologies which enable to provide optimized, tailored, and continuously updated solution for each customer.
