Aluminium SmelterChinaCO₂ reported
Qinghai Xining aluminium plant is an aluminium smelter in China with a reported capacity of 675,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Qinghai Xinheng Hydro Power Development Co Ltd. By capacity it ranks #43 of 141 aluminium smelters tracked in China. It emits about 1,434,468 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 334,375 cars.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3672976.
Przy 675,000 t of alumina/aluminum, Qinghai Xining aluminium plant jest znacznie powyżej medianę aluminium smelter w China (372,000 t of alumina/aluminum). Jego CO₂ na jednostkę pojemności wynosi w przybliżeniu 16% powyżej medianę aluminium smelter. Podsektor: aluminum. Jako aluminium smelter, wymaga intensywnego ciepła procesowego (typowo 600–900°C) do swoich głównych operacji przemysłowych — ciepła, które musi być dostarczane przez kotły, piece lub spalanie bezpośrednie, a straty przez nieisolowane zbiorniki i rury stanowią zmarnowane paliwo. Modułowa izolacja demontowalna może zmniejszyć te straty o 80–96%, chłodząc powierzchnie do ≤45°C, z zwrotem inwestycji często poniżej 2 lat. Huty aluminium używają dużych prądów elektrycznych do rafinacji tlenku glinu w stopiony aluminium powyżej 900°C, a metal w stanie gorącym musi płynąć przez tygle i urządzenia do odlewania.

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.
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 2,800 MWh/yr (≈ 560 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.
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.
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.
