Amperage Increase Program and Enablers in EGA Al Taweelah DX Technology Potlines

AluminiumAluminium smelters worldwide have been enticed by the idea of increasing amperage to boost overall production. Emirates Global AluminiumAluminium (EGA) has acquired extensive experience in ramping up amperage in various potlines. This article details EGA's experience and the challenges encountered during the amperage increaseAmperage increase in Al Taweelah (AT) Phase 1 potlines, which comprise two DX technologyDX Technology potlines: Potline 1 and Potline 2. The commissioning of the corresponding 756 pots was finalized in January 2011. Over time, the potlines underwent a gradual amperage increaseAmperage increase program, progressing from 350 to 437 kA. The article focuses on the latest phase of the amperage increaseAmperage increase program, specifically the transition from 420 to 437 kA, successfully completed in May 2023. It highlights the enablers that made the amperage increaseAmperage increase possible: rectifiers and busbar system capacity, the thermal balanceThermal balance of the pots, copper insertCopper insert collector bars, and extension of anodeAnode length.
