Product Recovery Plants

We manufacture high quality product recovery plants for different industrial requirements. Designed in compliance with strict international market standards, they offer superior performance with zero defects. These plants optimize manufacturing and minimize chances of failure and wastage during production.

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 and manufacture special tray-type absorbers for this purpose. Finally the gases are passed through columns to limit emissions within pollution control limits.

Absorption of HCl or HBr to produce concentrated acid is accompanied by generation of large amount of heat. Heat exchangers with expensive materials of construction are used to cool the acid. We have developed gas absorption systems, which do not require heat exchangers. This results in saving in capital costs.

Often sodium hypochlorite is produced in caustic chlorine plants by the absorption of chlorine gas in sodium hydroxide. The reaction is exothermic and wet chlorine is highly corrosive requiring coolers and special materials of construction. We can manufacture and supply these plants on turn-key basis.
