Idemitsu Kosan Keihin Refinery

Idemitsu Kosan Keihin Refinery is a refinery in Japan with a reported capacity of 70,000 BBL per day. It processes crude oil into fuels and petrochemical feedstocks through distillation, cracking and reforming. It is operated by Idemitsu Kosan Co Ltd. By capacity it ranks #20 of 21 oil refineries tracked in Japan. It emits about 767,457 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 178,894 cars. Its CO₂ per unit of capacity is about 30% above the median refinery.

Bağlamda: bu tesis nasıl karşılaştırılır

70,000 BBL per day'de, Idemitsu Kosan Keihin Refinery Japan'daki refinery'lerin medyanı altında 145,000 BBL per day'dir. Kapasite başına CO₂'si refinery'nin medyanı üstünde kabaca 28%'dir. Alt sektör: oil-and-gas-refining. refinery olarak, temel endüstriyel işlemleri için yoğun proses ısısı (tipik olarak 200–600°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. Rafineriler, enerji yoğun destilasyon ve kraking yoluyla ham petrolü yakıtlara ve petrokimya hammaddelerine ısıtır, fraksiyonlar ve kimyasal olarak dönüştürür — buhar üretimi ve ısı geri kazanımı için son derece taleplidir.

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