Acid Regeneration Plant
The hydrochloric acid used in
the pickling line after its use, when its concentration falls below 6%,
is sent for regeneration to the ARP installed. This reduces the
consumption of fresh acid and also the cost of treating the effluents of
In ARP the specific gravity is
increased and sprayed into a furnace called roaster,in the form of fine
mist. The reaction takes place inside the roaster and Iron Chloride is
converted to Iron Oxide in powder form and fumes of Hydrochloric Acid.
The Iro Oxide is collected from the bottom of the roaster and the HCL
fume is dissolved in the form of liquid HCL. This regenerated acid(RA)
is reused in the Pickling linesand the Iron Oxide is sold to the paint
1. Concentration of acid in regenerated acid
should be minimum 18%.
