| Manufacturing and creating any
products take quite a bit of materials and energy and
also leads to industrial waste that result in
harmful effects on environment.

Waste Acid generation from Pickle line in Steel industries is chemically
treated in a process named as “Spray
Roasting Technology”
The plant mainly consists of following
major process equipments: |
|
| |
|
|
|
| |
 |
ROASTER |
|
| |
|
Concentrated Pickle
liquor, comes into contact with hot
combustion product and reacts with the
O₂ and H₂O to form Iron oxide as the
following reactions take place. |
|
| |
|
 |
|
| |
|
VENTURI |
|
| |
|
Incoming hot gases from
Roaster gets quenched. |
|
| |
|
SEPERATOR |
|
| |
|
Gases gets separated
from liquid particles. |
|
| |
|
ABSORBER |
|
| |
|
Packed column to allow
absorption of chlorides from gases by
Counter flowing water. |
|
| |
|
SCRUBBER |
|
| |
|
packed column where
remaining traces of chloride & iron
oxide particle gets trapped. |
|
| |
|
STACK |
|
| |
|
Disposal of waste gases
at environmentally accepted altitude. |
|
| |
|
OXIDE BIN |
|
| |
|
Collection of oxide from
Roaster bottom. |

Acid Regeneration process is considered to be the most preferable technology available for treatment of Waste Acid generated from Pickling Line in Cold Rolling Mill. |
| |
|
|
| |
|
|
There is no discharge generated from the Acid Regeneration facility resulting in “Zero discharge” concept which Safe guard the fertile soil from contamination from the chemical waste discharged from conventional treatment plant and avoiding the deterioration of underground water. |
| |
|
|
| |
|
|
In this process desired concentration of Hydrochloric acid are re-generated and returned back to steel industries for use in the pickling line process and thus reduces demand of fresh acid purchase to a meager quantity. |
| |
|
|
| |
|
|
Iron oxide (Fe2O3) produced in this process is a saleable product which is used as raw material for ferrites, pigments, glass industries thus improving the economics of Acid Regeneration Plant. |
