Karmoy aluminium plant

Karmoy aluminium plant is an aluminium smelter in Norway with a reported capacity of 270,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Norsk Hydro ASA. By capacity it ranks #2 of 7 aluminium smelters tracked in Norway. It emits about 583,940 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 136,117 cars.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3673113.

文脈内で：この施設がどのように比較されるか

270,000 t of alumina/aluminumで、Karmoy aluminium plantはNorwayのaluminium smelterの中央値はるかに上 200,000 t of alumina/aluminum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。
