RUALR/RUALRS, a leading, global aluminium producer, announces the status of RA-400 cells modernisation project. The cell’s upgraded design and process parameters will allow reducing electricity consumption to less than 12,900 kWh per tonne with the current efficiency of more than 95.5% and at the amperage of 435 kA. The total project investment including the testing in a pilot area is estimated at USD 70 million.
The RA-400 is RUSAL’s own technology developed by the in-house Engineering and Technology Centre. The project is aimed to create an innovative cell with unique upgraded features: it would operate at 400-440 kA with the cell capacity of 3,300 kg per day and total fluoride emissions less than 0.2 kg per tonne. Sixteen RA-400 cells have been tried at the testing centre of the Sayanogorsk aluminium smelter.
‘We followed the highest standards while designing the cell. Apart from technical and technology standards it is important to meet production safety standards in pot rooms and to reduce emissions to as low as possible. The results that we have today can be compared to the best production practices of the world’s aluminium producers. In the current situation when electricity prices are at their highest, it is the technology that helps saving money’, said Viktor Mann, UC RUSAL’s Technical Director.
The engineering of the RA-400 upgrade project is expected to be completed by late 2014.
