Lanjigarh Alumina Refinery

Lanjigarh Alumina Refinery is an aluminium smelter in India with a reported capacity of 3,175,150 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. By capacity it ranks #1 of 20 aluminium smelters tracked in India. It emits about 6,635,219 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 1,546,671 cars.

Im Kontext: wie sich diese Anlage vergleicht

Bei 3,175,150 t of alumina/aluminum ist Lanjigarh Alumina Refinery deutlich über dem Medianwert von aluminium smelter in India (360,000 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.
