Karmoy aluminium plant

Karmoy aluminium plant is an aluminium smelter in Norway with a reported capacity of 270,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Norsk Hydro ASA. By capacity it ranks #2 of 7 aluminium smelters tracked in Norway. It emits about 583,940 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 136,117 cars.

Nel contesto: come si confronta questo impianto

Con 270,000 t of alumina/aluminum, Karmoy aluminium plant è ben al di sopra di la mediana di aluminium smelter in Norway (200,000 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.
