Aluminium SmelterChinaCO₂ reported

Gansu Longxi aluminium plant is an aluminium smelter in China with a reported capacity of 250,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Gansu Longxi Dongxing Smelter . By capacity it ranks #92 of 141 aluminium smelters tracked in China. It emits about 456,631 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 106,441 cars. Its CO₂ per unit of capacity is about 13% below the median aluminium smelter.

У контексті: як порівнюється це підприємство

При потужності 250,000 t of alumina/aluminum Gansu Longxi aluminium plant — це нижче медіана aluminium smelter у China (372,000 t of alumina/aluminum). Підсектор: aluminum. Як aluminium smelter, воно вимагає високотемпературного технологічного тепла (зазвичай 600–900°C) для основних промислових операцій — тепла, яке повинне подаватися котлами, печами або прямим спаленням, і втрати через неізольовані судини та трубопроводи представляють витрачене напразно паливо. Знімна модульна теплоізоляція може зменшити ці втрати на 80–96%, охолодивши поверхню обладнання до ≤45°C, з окупністю часто менше 2 років. Алюмінієві плавильні використовують великі електричні струми для рафінування глинозему в розплавлений алюміній вище 900°C, і розплавлений метал повинен текти через тиглі та ливарне обладнання.

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 2,100 MWh/yr (≈ 410 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.
