Tray Type Gas Absorbers

Acid is regenerated and recovered from the spent acid in steel pickling plants.  The spent acid containing chlorides of iron is oxidized in a fluidized bed reactor to produce iron oxide and HCl vapours.  Whereas iron oxide is a useful bye-product, the HCl is absorbed in stoichiometric quantities of water to obtain 17 to 20% hydrochloric acid and reused for pickling.  We design, manufacture and Supply special tray-type absorbers for the purpose.  Finally, the gases are passed through packed columns to limit emissions within pollution control limits.

Attributes :

• Smooth working
• Excellent pollution control limits
• Easy passage through packed columns
• High reliability

Used For :

• Absorbing HCl in stoichiometric water quantities
