Two-stage Dynawave Scrubber in gas cleaning system

Three Sulphuric Acid plants are installed with a total capacity of 1,470,000 TPA based on the DCDA process.  The plant design is provided by Monsanto Envirochem (USA).  The off gases from smelting furnace and PS converter containing Sulphur Dioxide (SO2) are delivered to the gas cleaning section-comprising two stages of reverse jet scrubbers.  Cleaned gases from final reverse jet scrubber are fed to two stage electrostatic precipitators to eliminate mist and residual dust particles from gases.  SO2 rich gases are further processed and converted into sulphuric acid of commercially acceptable quality.   Substantial storage capacity and a 3.5 km long pipeline feed sulphuric acid to vessel directly from storage tank.

News November 8, 2010 - Hindalco Industries Ltd has informed BSE that due to the breakdown of cooling tower of Sulfuric Acid Plant - 3 of the Copper Plant located at Dahej, Gujrat, there is a disruption of production in Smelter-3. The repair of the cooling tower is expected to be completed within a couple of weeks and after which normal production from Smelter-3 is expected to commence. This may cause loss of cathode production of around 8000MT.   The Company has adequate insurance policy covering the loss due to such breakdown and loss of profit.
