Kitimat aluminium plant

Kitimat aluminium plant is an aluminium smelter in Canada with a reported capacity of 435,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Rio Tinto Ltd. By capacity it ranks #4 of 11 aluminium smelters tracked in Canada. It emits about 924,435 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 215,486 cars.

在上下文中：该设施如何比较

在435,000 t of alumina/aluminum时，Kitimat aluminium plant是Canada中aluminium smelter的中位数远高于 314,000 t of alumina/aluminum。 子部门：aluminum。 作为aluminium smelter，它需要强烈的工艺热量（通常600–900°C）来进行其核心工业操作——必须通过锅炉、炉或直接燃烧供应的热量，通过未隔热的容器和管道的损失代表浪费的燃料。可拆卸模块化绝缘可以将这些损失减少80-96%，将表面冷却至≤45°C，投资回收期通常不到2年。 铝冶炼厂使用大电流将氧化铝精炼成900°C以上的熔融铝，热金属必须通过坩埚和铸造设备流动。

容量和CO₂强度比较从Climate TRACE工业设施数据计算得出；部门角色基于工程参考。
