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.
Tray Type Gas Absorbers for Acid Regeneration Plants
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.
Hydrochloric / Hydrobromic Acid Absorption With or
Without Heat Exchanger
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.
Hypochloride Production Plants
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.
