Acid Regeneration Plant
Tenova role as a pole of excellence in technologies concerning efficiency of the Acid Regeneration Plant is resumed in cutting-edge technologies, named BLUEdrivenTM Technology.
A significant advantage due to the sustainable improvements in industrial efficiency and performance.
Overview
The acid regeneration process is the total recovery of metal-free chloride solutions based on the pyro hydrolysis principle. Pyro hydrolysis 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.
Two technologies have been established:
Spray Roaster Technology
An Acid Regeneration Plant (ARP), equipped with the Spray Roaster technology, is operated at a lower temperature than the FLB, which is creating an economical benefit. A by-product is obtained as reddish powder with grain size of approximately 30 µm, which is highly demanded on the market. Many years of experience provide Tenova with specialized know-how in spray roaster technologies which enable to provide optimized, tailored, and continuously updated solutions for each customer.
Fluidized Bed Process
Under high temperature and continuous operation the process regenerates HCl acid (18%wt) and permits to sinter oxide forming grey granules up to 2 mm in size. The iron oxide granules are free of dust and contain almost no chlorides. It is mainly used be reused in the steel production (e.g. in the electric arc furnace) or sold as a by-product.
