Portland aluminium plant

Portland aluminium plant is an aluminium smelter in Australia with a reported capacity of 268,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Alcoa Portland Aluminium Pty Ltd. By capacity it ranks #14 of 15 aluminium smelters tracked in Australia. It emits about 574,610 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 133,942 cars.

En contexto: cómo se compara esta instalación

Con 268,000 t of alumina/aluminum, Portland aluminium plant está por debajo de la mediana de aluminium smelter en Australia (974,163 t of alumina/aluminum). Su CO₂ por unidad de capacidad es aproximadamente 63% por encima 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.
