Maputo aluminium plant

Maputo aluminium plant is an aluminium smelter in Mozambique with a reported capacity of 575,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by South32 Ltd. By capacity it ranks #1 of 2 aluminium smelters tracked in Mozambique. It emits about 1,272,345 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 296,584 cars. Its CO₂ per unit of capacity is about 6% above the median aluminium smelter.

En contexte: comment cette installation se compare

À 575,000 t of alumina/aluminum, Maputo aluminium plant est autour de la médiane des aluminium smelter en Mozambique (575,000 t of alumina/aluminum). Sous-secteur: aluminum. Comme aluminium smelter, elle nécessite une chaleur de procédé intensive (typiquement 600–900°C) pour ses opérations industrielles essentielles — chaleur qui doit être fournie par des chaudières, fours ou combustion directe, et les pertes par les récipients et tuyauteries non isolés représentent du combustible gaspillé. L'isolation modulaire amovible peut réduire ces pertes de 80–96%, refroidissant les surfaces à ≤45°C, avec des délais d'amortissement souvent inférieurs à 2 ans. Les fonderies d'aluminium utilisent de grands courants électriques pour raffiner l'alumine en aluminium fondu au-dessus de 900°C, et le métal chaud doit s'écouler à travers des creusets et des équipements de coulée.
