Tiwai Point aluminium plant

Tiwai Point aluminium plant is an aluminium smelter in New Zealand with a reported capacity of 330,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by New Zealand Aluminium Smelters . It emits about 707,542 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 164,928 cars.

Nel contesto: come si confronta questo impianto

Con 330,000 t of alumina/aluminum, Tiwai Point aluminium plant è attorno a la mediana di aluminium smelter in New Zealand (330,000 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.
