Aluminium SmelterChinaCO₂ reported
Nanshan aluminium plant is an aluminium smelter in China with a reported capacity of 840,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Shandong Nanshan Aluminium Co Ltd. By capacity it ranks #37 of 141 aluminium smelters tracked in China. It emits about 1,785,116 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 416,111 cars.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3673018.
عند 840,000 t of alumina/aluminum، يكون Nanshan aluminium plant أعلى بكثير من متوسط aluminium smelter في China (372,000 t of alumina/aluminum). CO₂ لكل وحدة سعة هو تقريباً 16% أعلى من متوسط aluminium smelter. 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.

A aluminium smelter like this runs hot equipment that sheds heat continuously: alumina calciner, casthouse furnaces, hot ducting (electrolysis itself is electric) (surface/process temperatures around 150–1,000 °C). These surfaces lose energy to the air year-round; removable modular insulation cuts that loss, brings outer surfaces to ≤45 °C, and unclips for inspection.
electrolysis is mostly electricity (Scope 2) + anode process; on-site combustion small - insulation mainly relevant to alumina refining/casthouse.
On an already-insulated site (pipes & valves in cladding / jackets), closing the remaining gaps, flanges and damaged sections and switching to removable covers indicatively recovers about 3,000 MWh/yr (≈ 610 t CO₂/yr) — scaled to this site's reported CO₂ within its sector. Bare or damaged surfaces recover several times more.
See Inzonex insulation → Estimate your site →
Indicative, not a measurement. Conservative floor for an already-insulated plant; a TIPCHECK on-site audit gives a measured figure. Industry context: EiiF TIPCHECK — industrial insulation can save ~14 Mtoe/yr in EU, payback typically <2 years.
Bare hot surfaces here exceed the touch-safe limit (EN ISO 13732-1); insulation to ≤45 °C is a worker-safety and compliance win. And before electrification, fuel-switching or CCS, eliminating surface heat loss is the cheapest, fastest, lowest-risk step — audit the bare spots first, rip-and-replace later.
Domestic energy-efficiency grants are limited here; industrial decarbonisation is mainly funded externally:
CBAM. Exporters of cement, steel, aluminium, fertiliser, hydrogen and electricity to the EU face the Carbon Border Adjustment Mechanism — cutting embedded emissions (efficiency + insulation) lowers the levy.
Routed via national development banks / accredited entities — not a direct factory grant. Verified 2026.
