Tiwai Point aluminium plant

Tiwai Point aluminium plant is an aluminium smelter in New Zealand with a reported capacity of 330,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by New Zealand Aluminium Smelters . It emits about 707,542 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 164,928 cars.

文脈内で：この施設がどのように比較されるか

330,000 t of alumina/aluminumで、Tiwai Point aluminium plantはNew Zealandのaluminium smelterの中央値約 330,000 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。

容量およびCO₂強度の比較はClimate TRACEの産業施設データから計算されました。セクターの役割は工学リファレンスに基づいています。
