Hoyanger aluminium plant

Hoyanger aluminium plant is an aluminium smelter in Norway with a reported capacity of 65,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Norsk Hydro ASA. By capacity it ranks #6 of 7 aluminium smelters tracked in Norway. It emits about 140,578 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 32,769 cars.

En contexte: comment cette installation se compare

À 65,000 t of alumina/aluminum, Hoyanger aluminium plant est en dessous de la médiane des aluminium smelter en Norway (200,000 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.
