Sao Luis Alumina Refinery and Aluminum Smelter

Sao Luis Alumina Refinery and Aluminum Smelter is an aluminium smelter in Brazil with a reported capacity of 3,850,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Alcoa Corp. By capacity it ranks #2 of 6 aluminium smelters tracked in Brazil. It emits about 6,392,925 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 1,490,192 cars. Its CO₂ per unit of capacity is about 21% below the median aluminium smelter.

En contexte: comment cette installation se compare

À 3,850,000 t of alumina/aluminum, Sao Luis Alumina Refinery and Aluminum Smelter est bien au-dessus de la médiane des aluminium smelter en Brazil (480,000 t of alumina/aluminum). Son CO₂ par unité de capacité est approximativement 26% en dessous de la médiane des aluminium smelter. 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.
