SN SEIXAL Siderurgia Nacional steel plant

SN SEIXAL Siderurgia Nacional steel plant is a steel plant in Portugal with a reported capacity of 1,100,000 t of steel. It produces crude steel from iron ore (blast furnace) or scrap (electric arc furnace). It is operated by SN SEIXAL Siderurgia Nacional SA. By capacity it ranks #1 of 2 steel plants tracked in Portugal. It emits about 127,032 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 29,611 cars. Its CO₂ per unit of capacity is about 79% below the median steel plant.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1567008.

Im Kontext: wie sich diese Anlage vergleicht

Bei 1,100,000 t of steel ist SN SEIXAL Siderurgia Nacional steel plant etwa um dem Medianwert von steel plant in Portugal (1,100,000 t of steel). Untersektor: iron-and-steel. Als steel plant benötigt es intensive Prozesswärme (typischerweise 800–1500°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. Stahlwerke verbrennen Kohle in Hochöfen oder nutzen Lichtbogenöfen zum Schmelzen von Schrott; in beiden Fällen muss das geschmolzene Metall über 1.500°C gehalten und durch umfangreiche heiße Rohrleitungen und Behälter geleitet werden.
