Technology Suppliers of Existing Alumina Refineries in India

Hi Friend,

In previous post, we have discussed about the Installed capacity of Alumina refineries in India as on today and proposed additions in capacities in the years to come. In present post, we thought of sharing with you the name of process technology suppliers who have contributed in installation and operation of these alumina refineries. As such, it may not be proper to mention that which company has supplied the best technology as each plant has got certain technology features which are missing in the other plant. 

The list of technology suppliers of existing Alumina refineries in India are tabulated here under-

We have analysed the technological features of the operative Alumina refineries and observed the following-

• Alumina refinery designed by Monte Cartini have efficient security filtration and Hydrate classification system.
• Aluterv FKI plants have better liquor decantation system which gives overflow liquor clarity at around 50 to 60 mgpl only.
• Worley Parson plants have improved digestion circuit compared to others.
• Alcan has efficient residue settling and washing system with proprietary equipment and improved hydrate precipitation circuit for achieving higher liquor productivity as well as consistency in product coarseness.

The information presented here are purely the personal observations and remarks of the author to the best his knowledge and experience in the field without any bias, favor or prejudice. If you have additional information on the subject, please come forward in sharing your views with members of Alumina fraternity.

We will welcome your views / suggestions / remarks / opinions / comments, if any.
