| Abstract Scope |
In Emirates Global Aluminium (EGA), the first pots were started up in 1979 in its Jebel Ali smelter (then called Dubai Aluminium - DUBAL), using Kaiser P69 cells at an amperage of 150 kA. In 2014 EGA started up its flagship, home grown DX+ Ultra technology at 450 kA. In 2017 DX+ Ultra was upgraded targeting operations at higher amperages, eventually reaching 480 kA by 2019. Now, in 2022, EGA succeeded in starting up DX+ Ultra technology at 500 kA. This was done on 5 pots in it’s Jebal Ali smelter research and development demonstration section called Eagle. This paper aims to describe some of the adjustments made from previous generation of DX+ Ultra technology to enable the additional 20 kA amperage increase and start up the pots at 500 kA. It also details some of the related challenges and results from the preheat, start-up and early operations periods |
