Hawesville aluminium plant

Hawesville aluminium plant is an aluminium smelter in United States with a reported capacity of 250,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. By capacity it ranks #3 of 9 aluminium smelters tracked in United States. It emits about 525,702 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 122,541 cars.

Im Kontext: wie sich diese Anlage vergleicht

Bei 250,000 t of alumina/aluminum ist Hawesville aluminium plant deutlich über dem Medianwert von aluminium smelter in United States (187,000 t of alumina/aluminum). 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.
