Kuala Tanjung aluminium plant

Kuala Tanjung aluminium plant is an aluminium smelter in Indonesia with a reported capacity of 300,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by PT Indonesia Asahan Aluminium . By capacity it ranks #3 of 5 aluminium smelters tracked in Indonesia. It emits about 580,039 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 135,207 cars. Its CO₂ per unit of capacity is about 7% below the median aluminium smelter.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3673069.

En contexto: cómo se compara esta instalación

Con 300,000 t of alumina/aluminum, Kuala Tanjung aluminium plant está alrededor de la mediana de aluminium smelter en Indonesia (300,000 t of alumina/aluminum). Su CO₂ por unidad de capacidad es aproximadamente 7% por debajo de la mediana de aluminium smelter. 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.
