| Abstract Scope |
ALBA (Aluminium Bahrain) is one of unique primary Aluminium smelters who has its own calciner plant to produce CPC, by converting different types of GPC to CPC. The quality of GPC has a strong influence on the properties of the anodes. Due to market variations and price fluctuation, the properties of GPC purchased vary depending on the source. In addition, with latest expansion of Alba being the largest smelters outside China, Alba has to purchase ready CPC to top up the shortage in Calciner capacity. Such changes bring up great challenges to both Calciner and Carbon operation team to manage these variations through precise blending and tuning process parameters to achieve optimum anodes quality. This paper discusses ALBA strategy on managing the variations of GPC properties along with purchased CPC on quality of anodes in terms of desulphurization, anode density, baking level, stack emissions and other anode properties. |
