Gramercy Alumina Refinery

Gramercy Alumina Refinery is an aluminium smelter in United States with a reported capacity of 1,200,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. By capacity it ranks #1 of 9 aluminium smelters tracked in United States. It emits about 610,790 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 142,375 cars. Its CO₂ per unit of capacity is about 76% below the median aluminium smelter.

Nel contesto: come si confronta questo impianto

Con 1,200,000 t of alumina/aluminum, Gramercy Alumina Refinery è ben al di sopra di la mediana di aluminium smelter in United States (187,000 t of alumina/aluminum). Il suo CO₂ per unità di capacità è approssimativamente 76% 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.
