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.

En contexto: cómo se compara esta instalación

Con 1,200,000 t of alumina/aluminum, Gramercy Alumina Refinery está muy por encima de la mediana de aluminium smelter en United States (187,000 t of alumina/aluminum). Su CO₂ por unidad de capacidad es aproximadamente 76% por debajo de la mediana de aluminium smelter. Subsector: aluminum. Como aluminium smelter, requiere calor de proceso intenso (típicamente 600–900°C) para sus operaciones industriales centrales — calor que debe ser suministrado por calderas, hornos o combustión directa, y las pérdidas a través de recipientes y tuberías sin aislar representan combustible desperdiciado. El aislamiento modular desmontable puede reducir esas pérdidas en un 80–96%, enfriando superficies a ≤45°C, con amortización a menudo inferior a 2 años. Las fundiciones de aluminio utilizan grandes corrientes eléctricas para refinar alúmina en aluminio fundido por encima de 900°C, y el metal caliente debe fluir a través de crisoles y equipos de colada.
