Hejin Xian aluminium plant

Hejin Xian aluminium plant is an aluminium smelter in China with a reported capacity of 120,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by China Hongqiao Group Ltd. By capacity it ranks #121 of 141 aluminium smelters tracked in China. It emits about 219,183 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 51,092 cars. Its CO₂ per unit of capacity is about 13% below the median aluminium smelter.

В контексте: как это предприятие сравнивается

На мощности 120,000 t of alumina/aluminum Hejin Xian aluminium plant — это ниже медианная aluminium smelter в China (372,000 t of alumina/aluminum). Подсектор: aluminum. Как aluminium smelter, оно требует высокотемпературного технологического тепла (обычно 600–900°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. Алюминиевые плавильни используют большие электрические токи для рафинирования глинозёма в расплавленный алюминий выше 900°C, и расплавленный металл должен течь через тигли и литейное оборудование.

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