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.

Nel contesto: come si confronta questo impianto

Con 268,000 t of alumina/aluminum, Portland aluminium plant è al di sotto di la mediana di aluminium smelter in Australia (974,163 t of alumina/aluminum). Il suo CO₂ per unità di capacità è approssimativamente 63% al di sopra di la mediana di aluminium smelter. Sottosettore: aluminum. Come aluminium smelter, richiede calore di processo intenso (tipicamente 600–900°C) per le sue operazioni industriali essenziali — calore che deve essere fornito da caldaie, forni o combustione diretta, e le perdite attraverso recipienti e tubazioni non isolati rappresentano carburante sprecato. L'isolamento modulare removibile può ridurre queste perdite dell'80–96%, raffreddando superfici a ≤45°C, con payback spesso inferiore a 2 anni. Le fonderie di alluminio utilizzano grandi correnti elettriche per raffinare l'allumina in alluminio fuso sopra i 900°C, e il metallo caldo deve fluire attraverso crogioli e attrezzature di fonderia.
