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.

Bağlamda: bu tesis nasıl karşılaştırılır

2,737,588 t of alumina/aluminum'de, Qiandongnan Miao and Dong Autonomous Prefecture China'daki aluminium smelter'lerin medyanı çok üstünde 372,000 t of alumina/aluminum'dir. Kapasite başına CO₂'si aluminium smelter'nin medyanı altında kabaca 26%'dir. Alt sektör: aluminum. aluminium smelter olarak, temel endüstriyel işlemleri için yoğun proses ısısı (tipik olarak 600–900°C) gerektirir — kazanlar, fırınlar veya doğrudan yanma ile sağlanması gereken ısı, ve izolasyon yapılmamış kaplar ve boruların kayıpları harcanan yakıtı temsil eder. Modüler çıkarılabilir yalıtım bu kayıpları %80–96 oranında azaltabilir, yüzeyleri ≤45°C'ye soğutabilir, geri ödeme süresi genellikle 2 yıldan azdır. Alüminyum eritmeleri, alüminayı 900°C'nin üstündeki eritilmiş alüminyuma rafine etmek için büyük elektrik akımları kullanır ve sıcak metal pota ve dökme ekipmanı aracılığıyla akmalıdır.

Kapasite ve CO₂ yoğunluğu karşılaştırması Climate TRACE endüstriyel tesis verilerinden hesaplanmıştır; sektör rolü mühendislik referansına dayanmaktadır.
