Maputo aluminium plant

Maputo aluminium plant is an aluminium smelter in Mozambique with a reported capacity of 575,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by South32 Ltd. By capacity it ranks #1 of 2 aluminium smelters tracked in Mozambique. It emits about 1,272,345 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 296,584 cars. Its CO₂ per unit of capacity is about 6% above the median aluminium smelter.

在上下文中：该设施如何比较

在575,000 t of alumina/aluminum时，Maputo aluminium plant是Mozambique中aluminium smelter的中位数约 575,000 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。
