EGA Addresses Calcined Petroleum Coke (CPC) Quality Variation Impact on Anode Quality and Performance
摘要
The aluminumAluminum industryIndustry heavily relies on carbon anodesCarbon anode, which are critical components in the electrolysis process of aluminum productionAluminum production. Traditionally, high-quality Calcined Petroleum CokeCalcined Petroleum Cokes (CPC) (CPCCalcined Petroleum Cokes (CPC)) is used as the primary raw material due to its superior properties. The decline in CPCCalcined Petroleum Cokes (CPC) quality globally is a complex issue driven by variationsVariations in Green Petroleum CokeGreen Petroleum Cokes (GPC) (GPCGreen Petroleum Cokes (GPC)) raw material quality, economic pressures, technological limitations, regulatory challenges, and shifting market demands. Addressing these challenges requires a collaborative effort from industryIndustry stakeholders, including investments in technology, improvements in raw material sourcing, and adherence to quality standards to ensure the production of high-quality CPCCalcined Petroleum Cokes (CPC). but the high cost and environmental impactEnvironmental Impact of procuring such materials drive the need for more sustainable alternatives. This study addresses the approach which Emirates Global AluminiumAluminium (EGA) has adopted of using CPCCalcined Petroleum Cokes (CPC) with variable quality, characterized by two parameters which are vibrating bulk densityBulk density and coke sizing, for producing carbon anodesCarbon anode while maintaining performance standards and enhancing sustainabilitySustainability. Changes in CPCCalcined Petroleum Cokes (CPC) quality was subjected to various preprocessing blending, screening and crushing to improve its compatibility for anodeAnode production. These treatments included blending different quality CPCCalcined Petroleum Cokes (CPC) to manage and optimize the carbon anodeCarbon anode structure and characteristics. The processed CPCCalcined Petroleum Cokes (CPC) was then used in the production of carbon anodesCarbon anode, and the resulting anodesAnode were evaluated for key performance parameters including electrical resistivityElectrical resistivity and baked anodeAnode density.
