Hoyanger aluminium plant

Hoyanger aluminium plant is an aluminium smelter in Norway with a reported capacity of 65,000 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 #6 of 7 aluminium smelters tracked in Norway. It emits about 140,578 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 32,769 cars.

Bağlamda: bu tesis nasıl karşılaştırılır

65,000 t of alumina/aluminum'de, Hoyanger aluminium plant Norway'daki aluminium smelter'lerin medyanı altında 200,000 t of alumina/aluminum'dir. Alt sektör: aluminum. aluminium smelter olarak, temel endüstriyel işlemleri için yoğun proses ısısı (tipik olarak 600–900°C) gerektirir — kazanlar, fırınlar veya doğrudan yanma ile sağlanması gereken ısı, ve izolasyon yapılmamış kaplar ve boruların kayıpları harcanan yakıtı temsil eder. Modüler çıkarılabilir yalıtım bu kayıpları %80–96 oranında azaltabilir, yüzeyleri ≤45°C'ye soğutabilir, geri ödeme süresi genellikle 2 yıldan azdır. Alüminyum eritmeleri, alüminayı 900°C'nin üstündeki eritilmiş alüminyuma rafine etmek için büyük elektrik akımları kullanır ve sıcak metal pota ve dökme ekipmanı aracılığıyla akmalıdır.

Kapasite ve CO₂ yoğunluğu karşılaştırması Climate TRACE endüstriyel tesis verilerinden hesaplanmıştır; sektör rolü mühendislik referansına dayanmaktadır.
