Steel Plant in Portugal. Approximate location 38.62303, -9.07312.

Steel PlantPortugalCO₂ reported

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.

В контексте: как это предприятие сравнивается

На мощности 1,100,000 t of steel SN SEIXAL Siderurgia Nacional steel plant — это примерно медианная steel plant в Portugal (1,100,000 t of steel). Подсектор: iron-and-steel. Как steel plant, оно требует высокотемпературного технологического тепла (обычно 800–1500°C) для основных промышленных операций — тепла, которое должно подаваться котлами, печами или прямым сжиганием, и потери через неизолированные сосуды и трубопроводы представляют потраченное впустую топливо. Съёмная модульная теплоизоляция может снизить эти потери на 80–96%, охладив поверхность оборудования до ≤45°C, с окупаемостью часто менее 2 лет. Сталелитейные заводы сжигают уголь в доменных печах или используют электрические дуги для плавления лома; в обоих случаях расплавленный металл должен находиться выше 1500°C и транспортироваться через обширные горячие трубопроводы и сосуды.

Сравнение производительности и интенсивности CO₂ рассчитано на основе данных промышленных объектов Climate TRACE; роль сектора основана на инженерных справочниках.
