Sao Luis Alumina Refinery and Aluminum Smelter

Sao Luis Alumina Refinery and Aluminum Smelter is an aluminium smelter in Brazil with a reported capacity of 3,850,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Alcoa Corp. By capacity it ranks #2 of 6 aluminium smelters tracked in Brazil. It emits about 6,392,925 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 1,490,192 cars. Its CO₂ per unit of capacity is about 21% below the median aluminium smelter.

En contexto: cómo se compara esta instalación

Con 3,850,000 t of alumina/aluminum, Sao Luis Alumina Refinery and Aluminum Smelter está muy por encima de la mediana de aluminium smelter en Brazil (480,000 t of alumina/aluminum). Su CO₂ por unidad de capacidad es aproximadamente 26% 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.
