Shizuoka (Shimizu) Alumina Refinery

Shizuoka (Shimizu) Alumina Refinery is an aluminium smelter in Japan with a reported capacity of 381,020 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Nippon Light Metal Co Ltd. By capacity it ranks #1 of 2 aluminium smelters tracked in Japan. It emits about 796,230 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 185,601 cars.

En contexto: cómo se compara esta instalación

Con 381,020 t of alumina/aluminum, Shizuoka (Shimizu) Alumina Refinery está alrededor de la mediana de aluminium smelter en Japan (381,020 t of alumina/aluminum). 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.
