Qiandongnan Miao and Dong Autonomous Prefecture

Qiandongnan Miao and Dong Autonomous Prefecture is an aluminium smelter in China with a reported capacity of 2,737,588 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. By capacity it ranks #15 of 141 aluminium smelters tracked in China. It emits about 3,714,359 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 865,818 cars. Its CO₂ per unit of capacity is about 35% below the median aluminium smelter.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-48193121.

Em contexto: como esta instalação se compara

Com 2,737,588 t of alumina/aluminum, Qiandongnan Miao and Dong Autonomous Prefecture é bem acima de a mediana de aluminium smelter em China (372,000 t of alumina/aluminum). Seu CO₂ por unidade de capacidade é aproximadamente 26% abaixo de a mediana de aluminium smelter. Subsetor: aluminum. Como aluminium smelter, requer calor de processo intenso (tipicamente 600–900°C) para suas operações industriais centrais — calor que deve ser fornecido por caldeiras, fornos ou combustão direta, e as perdas através de vasos e tubulações não isolados representam combustível desperdiçado. O isolamento modular removível pode reduzir essas perdas em 80–96%, esfriando superfícies a ≤45°C, com payback geralmente inferior a 2 anos. As fundições de alumínio usam grandes correntes elétricas para refinar alumina em alumínio fundido acima de 900°C, e o metal quente deve fluir através de cadinhos e equipamentos de fundição.
