Zunyi Xian, Guizhou aluminium plant

Zunyi Xian, Guizhou aluminium plant is an aluminium smelter in China with a reported capacity of 260,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Aluminum Corporation of China . By capacity it ranks #89 of 141 aluminium smelters tracked in China. It emits about 474,896 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 110,698 cars. Its CO₂ per unit of capacity is about 13% below the median aluminium smelter.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-43765195.

En contexto: cómo se compara esta instalación

Con 260,000 t of alumina/aluminum, Zunyi Xian, Guizhou aluminium plant está por debajo de la mediana de aluminium smelter en China (372,000 t of alumina/aluminum). Subsector: aluminum. Como aluminium smelter, requiere calor de proceso intenso (típicamente 600–900°C) para sus operaciones industriales centrales — calor que debe ser suministrado por calderas, hornos o combustión directa, y las pérdidas a través de recipientes y tuberías sin aislar representan combustible desperdiciado. El aislamiento modular desmontable puede reducir esas pérdidas en un 80–96%, enfriando superficies a ≤45°C, con amortización a menudo inferior a 2 años. Las fundiciones de aluminio utilizan grandes corrientes eléctricas para refinar alúmina en aluminio fundido por encima de 900°C, y el metal caliente debe fluir a través de crisoles y equipos de colada.
