Yunnan Qujing aluminium plant

Yunnan Qujing aluminium plant is an aluminium smelter in China with a reported capacity of 380,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Yunnan Dongyuan Qujing Aluminium Co Ltd. By capacity it ranks #69 of 141 aluminium smelters tracked in China. It emits about 807,552 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 188,241 cars.

Im Kontext: wie sich diese Anlage vergleicht

Bei 380,000 t of alumina/aluminum ist Yunnan Qujing aluminium plant etwa um dem Medianwert von aluminium smelter in China (372,000 t of alumina/aluminum). Sein CO₂ pro Kapazitätseinheit liegt ungefähr 16% über dem Medianwert von aluminium smelter. Untersektor: aluminum. Als aluminium smelter benötigt es intensive Prozesswärme (typischerweise 600–900°C) für seinen Kernbetrieb — Wärme, die durch Dampfkessel, Öfen oder direkte Verbrennung geliefert werden muss, und Verluste durch ungedämmte Behälter und Rohrleitungen stellen verschwendeten Brennstoff dar. Modulare abnehmbare Dämmung kann diese Verluste um 80–96% senken, Oberflächen auf ≤45°C kühlen, mit Amortisationszeiten oft unter 2 Jahren. Aluminiumhütten nutzen große Elektroströme, um Tonerde in geschmolzenes Aluminium über 900°C zu raffinieren, und das heiße Metall muss durch Tiegel und Gießausrüstung fließen.
