Alma aluminium plant

Alma aluminium plant is an aluminium smelter in Canada with a reported capacity of 480,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Rio Tinto Ltd. By capacity it ranks #3 of 11 aluminium smelters tracked in Canada. It emits about 1,020,066 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 237,778 cars.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3672966.

En contexto: cómo se compara esta instalación

Con 480,000 t of alumina/aluminum, Alma aluminium plant está muy por encima de la mediana de aluminium smelter en Canada (314,000 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.
