EGA and Inalum complete start-up of upgraded pilot pots

Emirates Global Aluminium and Inalum have completed the start-up of five pilot reduction cells at Inalum’s Kuala Tanjung aluminium smelter in Indonesia.

EGA and Inalum celebrate the start-up of the five pilot pots at Inalum's Kuala Tanjung smelter

The pilot reduction cells, which were upgraded with EGA’s technological expertise, are the first step in a larger planned project to upgrade a further 298 pots in Potlines 1 and 3 of the smelter. The project aims to increase the amperage of the reduction cells from 195 to 215 kA and boost production capacity by around 10 %. EGA has completed a series of similar upgrades across its Jebel Ali site in Dubai and Al Taweelah site in Abu Dhabi in recent decades.

EGA technologists and engineers have worked more than 10,000 hours on the Kuala Tanjung upgrade project so far in design and implementation, including 4,300 hours spent at the smelter. 

Start-up of these pilot pots an important milestone

EGA CEO Abdulnasser Bin Kalban commented: “The successful completion of the start-up of these pilot pots is an important milestone both in our project to deploy EGA’s technological know-how in Indonesia, and our potentially wider partnership with Inalum. EGA’s technology team has a decades-long track record of success, creating value for EGA not just in the UAE but internationally.” Danny Praditya, president director of Inalum, said: “Inalum appreciated this collaboration on the pilot project, which has had excellent results. We are now evaluating these results for the next phase of the wider project.”

The upgrades to the pilot reduction cells at Kuala Tanjung include significant improvements to superstructure and potshells, as well as incorporating EGA’s proprietary pot control system which is state-of-the-art software that maximizes metal production while reducing energy consumption and environmental emissions.

EGA has signed a separate agreement with Inalum giving the UAE company the exclusive right to provide its proprietary DX+ Ultra aluminium smelting technology for an expansion of the Kuala Tanjung smelter, should prove feasible.

EGA to offtake much of the produced metal

EGA also has the right to take a minority equity stake in the project and to offtake much of the produced metal. EGA’s requirement for an investment or metal offtake is that the project uses renewable power. The existing aluminium Kuala Tanjung smelter uses electricity generated with hydropower.

EGA has developed its own aluminium smelting technology for more than 30 years. DX+ Ultra, EGA’s latest industrialised technology, is amongst the most efficient in the global aluminium industry.

EGA was the first UAE industrial company to license its core process technology internationally, in a deal with Aluminium Bahrain in 2016.
