Zhengxing aluminium plant

Zhengxing aluminium plant is an aluminium smelter in China with a reported capacity of 50,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. By capacity it ranks #139 of 141 aluminium smelters tracked in China. It emits about 91,326 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 21,288 cars. Its CO₂ per unit of capacity is about 13% below the median aluminium smelter.

Nel contesto: come si confronta questo impianto

Con 50,000 t of alumina/aluminum, Zhengxing aluminium plant è al di sotto di la mediana di aluminium smelter in China (372,000 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.
