Samalaju aluminium plant

Samalaju aluminium plant is an aluminium smelter in Malaysia with a reported capacity of 960,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Press Metal Samalaju . By capacity it ranks #1 of 2 aluminium smelters tracked in Malaysia. It emits about 1,856,123 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 432,663 cars. Its CO₂ per unit of capacity is about 7% below the median aluminium smelter.

Im Kontext: wie sich diese Anlage vergleicht

Bei 960,000 t of alumina/aluminum ist Samalaju aluminium plant etwa um dem Medianwert von aluminium smelter in Malaysia (960,000 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.
