Aluminium SmelterChinaCO₂ reported

Emei aluminium plant is an aluminium smelter in China with a reported capacity of 350,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Leshan Hongjia Metal Co Ltd. By capacity it ranks #75 of 141 aluminium smelters tracked in China. It emits about 743,798 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 173,379 cars.

В контексте: как это предприятие сравнивается

На мощности 350,000 t of alumina/aluminum Emei aluminium plant — это примерно медианная aluminium smelter в China (372,000 t of alumina/aluminum). Его выброс CO₂ на единицу мощности примерно на 16% выше медианной aluminium smelter. 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.

Heat loss & insulation profile

A aluminium smelter like this runs hot equipment that sheds heat continuously: alumina calciner, casthouse furnaces, hot ducting (electrolysis itself is electric) (surface/process temperatures around 150–1,000 °C). These surfaces lose energy to the air year-round; removable modular insulation cuts that loss, brings outer surfaces to ≤45 °C, and unclips for inspection.

electrolysis is mostly electricity (Scope 2) + anode process; on-site combustion small - insulation mainly relevant to alumina refining/casthouse.

Indicative recoverable energy

On an already-insulated site (pipes & valves in cladding / jackets), closing the remaining gaps, flanges and damaged sections and switching to removable covers indicatively recovers about 2,300 MWh/yr (≈ 460 t CO₂/yr) — scaled to this site's reported CO₂ within its sector. Bare or damaged surfaces recover several times more.

See Inzonex insulation → Estimate your site →

Indicative, not a measurement. Conservative floor for an already-insulated plant; a TIPCHECK on-site audit gives a measured figure. Industry context: EiiF TIPCHECK — industrial insulation can save ~14 Mtoe/yr in EU, payback typically <2 years.

Safety & the no-regret first step

Bare hot surfaces here exceed the touch-safe limit (EN ISO 13732-1); insulation to ≤45 °C is a worker-safety and compliance win. And before electrification, fuel-switching or CCS, eliminating surface heat loss is the cheapest, fastest, lowest-risk step — audit the bare spots first, rip-and-replace later.

External climate finance your country can access

Domestic energy-efficiency grants are limited here; industrial decarbonisation is mainly funded externally:

CBAM. Exporters of cement, steel, aluminium, fertiliser, hydrogen and electricity to the EU face the Carbon Border Adjustment Mechanism — cutting embedded emissions (efficiency + insulation) lowers the levy.

Routed via national development banks / accredited entities — not a direct factory grant. Verified 2026.
