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.

文脈内で：この施設がどのように比較されるか

1,200,000 t of alumina/aluminumで、Gramercy Alumina RefineryはUnited Statesのaluminium smelterの中央値はるかに上 187,000 t of alumina/aluminumです。 容量あたりのCO₂は、aluminium smelterの中央値下約76%です。 サブセクター：aluminum。 aluminium smelterとして、その中核的な産業操業に対して激しいプロセス熱（通常600–900°C）が必要です。この熱はボイラー、炉、または直接燃焼によって供給される必要があり、未断熱容器および配管からの損失は無駄な燃料を表します。モジュール式脱着可能な断熱は、これらの損失を80～96%削減でき、表面を≤45°Cに冷却でき、回収期間は通常2年未満です。 アルミニウム製錬所は大きな電流を使用して、900°C以上の溶融アルミニウムにアルミナを精製し、高温金属は坩堝および鋳造装置を通じて流れなければなりません。
