Pickling Acid Recovery

Pickling Acid Recovery 

The flowchart shows the continuous treatment of  pickling tank to keep iron content around 40 gr /lit , and concentration of  HCl 10% wt/wt   .These parameters will minimize pickling time and give constant quantities  of acid and iron salts which move to rinsing water.

In this case, it easy to design the capacity of rinsing water treatment unit ,
