Grande Baie aluminium plant

Grande Baie aluminium plant is an aluminium smelter in Canada with a reported capacity of 236,000 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 #9 of 11 aluminium smelters tracked in Canada. It emits about 501,533 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 116,907 cars.

Nel contesto: come si confronta questo impianto

Con 236,000 t of alumina/aluminum, Grande Baie aluminium plant è al di sotto di la mediana di aluminium smelter in Canada (314,000 t of alumina/aluminum). 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.
