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.

1,100,000 t of steel'de, SN SEIXAL Siderurgia Nacional steel plant Portugal'daki steel plant'lerin medyanı yaklaşık 1,100,000 t of steel'dir. Alt sektör: iron-and-steel. steel plant olarak, temel endüstriyel işlemleri için yoğun proses ısısı (tipik olarak 800–1500°C) gerektirir — kazanlar, fırınlar veya doğrudan yanma ile sağlanması gereken ısı, ve izolasyon yapılmamış kaplar ve boruların kayıpları harcanan yakıtı temsil eder. Modüler çıkarılabilir yalıtım bu kayıpları %80–96 oranında azaltabilir, yüzeyleri ≤45°C'ye soğutabilir, geri ödeme süresi genellikle 2 yıldan azdır. Çelik fabrikaları yüksek ocaklarda kömür yakar veya hurda ergitmek için elektrik ark kullanır; her iki durumda da eritilmiş metal 1.500°C'nin üstünde tutulmalı ve geniş sıcak borular ve kaplar aracılığıyla aktarılmalıdır.

Kapasite ve CO₂ yoğunluğu karşılaştırması Climate TRACE endüstriyel tesis verilerinden hesaplanmıştır; sektör rolü mühendislik referansına dayanmaktadır.
