Boké Prefecture

Boké Prefecture is an aluminium smelter in Guinea with a reported capacity of 555,356 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. By capacity it ranks #2 of 3 aluminium smelters tracked in Guinea. It emits about 1,160,546 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 270,524 cars.

Nel contesto: come si confronta questo impianto

Con 555,356 t of alumina/aluminum, Boké Prefecture è attorno a la mediana di aluminium smelter in Guinea (555,356 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.
