SN MAIA Siderurgia Nacional steel plant

Steel Plant in Portugal. Approximate location 41.25449, -8.5551.

Steel PlantPortugalCO₂ reported

SN MAIA Siderurgia Nacional steel plant is a steel plant in Portugal with a reported capacity of 600,000 t of steel. It produces crude steel from iron ore (blast furnace) or scrap (electric arc furnace). It is operated by SN MAIA Siderurgia Nacional SA. By capacity it ranks #2 of 2 steel plants tracked in Portugal. It emits about 69,290 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 16,152 cars. Its CO₂ per unit of capacity is about 79% below the median steel plant.

En contexte: comment cette installation se compare

À 600,000 t of steel, SN MAIA Siderurgia Nacional steel plant est en dessous de la médiane des steel plant en Portugal (1,100,000 t of steel). Sous-secteur: iron-and-steel. Comme steel plant, elle nécessite une chaleur de procédé intensive (typiquement 800–1500°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 aciéries brûlent du charbon dans des hauts fourneaux ou utilisent des arcs électriques pour fondre des ferrailles; dans les deux cas, le métal en fusion doit être maintenu au-dessus de 1.500°C et transféré à travers des tuyauteries et récipients chauds étendus.
