Zunyi Xian, Guizhou aluminium plant

Zunyi Xian, Guizhou aluminium plant is an aluminium smelter in China with a reported capacity of 260,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Aluminum Corporation of China . By capacity it ranks #89 of 141 aluminium smelters tracked in China. It emits about 474,896 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 110,698 cars. Its CO₂ per unit of capacity is about 13% below the median aluminium smelter.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-43765195.

في السياق: كيف يتم مقارنة هذا المنشأة

عند 260,000 t of alumina/aluminum، يكون Zunyi Xian, Guizhou aluminium plant أقل من متوسط aluminium smelter في China (372,000 t of alumina/aluminum). القطاع الفرعي: aluminum. كـ aluminium smelter، يتطلب حرارة عملية مكثفة (عادة 600–900°C) لعملياته الصناعية الأساسية — حرارة يجب توفيرها بواسطة الغلايات أو الأفران أو الاحتراق المباشر، والخسائر من خلال الحاويات والأنابيب غير المعزولة تمثل وقود مهدر. يمكن للعزل المعياري القابل للإزالة أن يقلل هذه الخسائر بمقدار 80-96٪، وتبريد الأسطح إلى ≤45°C، مع فترة استرجاع غالباً أقل من سنتين. تستخدم مصاهر الألومنيوم تيارات كهربائية كبيرة لتحسين الألومينا إلى ألومنيوم مذاب فوق 900°C، ويجب أن يتدفق المعدن الساخن عبر البواتق ومعدات الصب.

مقارنة السعة وكثافة CO₂ محسوبة من بيانات منشآت Climate TRACE الصناعية؛ دور القطاع بناءً على مرجع الهندسة.
