Wenshan Alumina Refinery & Smelter

Wenshan Alumina Refinery & Smelter is an aluminium smelter in China with a reported capacity of 1,400,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Yunnan Aluminium Co Ltd. By capacity it ranks #24 of 141 aluminium smelters tracked in China. It emits about 1,899,520 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 442,779 cars. Its CO₂ per unit of capacity is about 35% below the median aluminium smelter.

Nel contesto: come si confronta questo impianto

Con 1,400,000 t of alumina/aluminum, Wenshan Alumina Refinery & Smelter è ben al di sopra di la mediana di aluminium smelter in China (372,000 t of alumina/aluminum). Il suo CO₂ per unità di capacità è approssimativamente 26% al di sotto 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.
