Steel PlantBrazilCO₂ reported

CSN Volta Redonda steel plant is a steel plant in Brazil with a reported capacity of 6,251,000 t of steel. It produces crude steel from iron ore (blast furnace) or scrap (electric arc furnace). It is operated by Companhia Siderúrgica Nacional SA. By capacity it ranks #2 of 22 steel plants tracked in Brazil. It emits about 7,646,497 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 1,782,400 cars. Its CO₂ per unit of capacity is about 126% above the median steel plant.

في السياق: كيف يتم مقارنة هذا المنشأة

عند 6,251,000 t of steel، يكون CSN Volta Redonda steel plant أعلى بكثير من متوسط steel plant في Brazil (1,000,000 t of steel). CO₂ لكل وحدة سعة هو تقريباً 117% أعلى من متوسط steel plant. القطاع الفرعي: iron-and-steel. كـ steel plant، يتطلب حرارة عملية مكثفة (عادة 800–1500°C) لعملياته الصناعية الأساسية — حرارة يجب توفيرها بواسطة الغلايات أو الأفران أو الاحتراق المباشر، والخسائر من خلال الحاويات والأنابيب غير المعزولة تمثل وقود مهدر. يمكن للعزل المعياري القابل للإزالة أن يقلل هذه الخسائر بمقدار 80-96٪، وتبريد الأسطح إلى ≤45°C، مع فترة استرجاع غالباً أقل من سنتين. تحرق مصانع الصلب الفحم في الأفران العالية أو تستخدم الأقواس الكهربائية لصهر الخردة؛ في كلا الحالتين يجب الاحتفاظ بالمعدن المذاب فوق 1,500°C ونقله عبر الأنابيب والحاويات الساخنة الواسعة.

مقارنة السعة وكثافة CO₂ محسوبة من بيانات منشآت Climate TRACE الصناعية؛ دور القطاع بناءً على مرجع الهندسة.
