CSN Volta Redonda steel plant

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.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32440381.

Em contexto: como esta instalação se compara

Com 6,251,000 t of steel, CSN Volta Redonda steel plant é bem acima de a mediana de steel plant em Brazil (1,000,000 t of steel). Seu CO₂ por unidade de capacidade é aproximadamente 117% acima de a mediana de steel plant. Subsetor: iron-and-steel. Como steel plant, requer calor de processo intenso (tipicamente 800–1500°C) para suas operações industriais centrais — calor que deve ser fornecido por caldeiras, fornos ou combustão direta, e as perdas através de vasos e tubulações não isolados representam combustível desperdiçado. O isolamento modular removível pode reduzir essas perdas em 80–96%, esfriando superfícies a ≤45°C, com payback geralmente inferior a 2 anos. As usinas de aço queimam carvão em altos-fornos ou usam arcos elétricos para derreter sucata; em ambos os casos, o metal fundido deve ser mantido acima de 1.500°C e transferido através de tubulações e vasos de calor extensos.
