Keiyo Ethylene , Ichihara, Chiba

Keiyo Ethylene , Ichihara, Chiba is a petrochemical in Japan with a reported capacity of 690,000 t of ethylene. It cracks hydrocarbon feedstocks into building-block chemicals such as ethylene and propylene. It is operated by Sumitomo Chemical Co Ltd. By capacity it ranks #1 of 12 petrochemical plants tracked in Japan. It emits about 970,117 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 226,134 cars. Its CO₂ per unit of capacity is about 5% above the median petrochemical.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-731952.

Bağlamda: bu tesis nasıl karşılaştırılır

690,000 t of ethylene'de, Keiyo Ethylene , Ichihara, Chiba Japan'daki petrochemical'lerin medyanı çok üstünde 493,000 t of ethylene'dir. Alt sektör: petrochemical-steam-cracking. petrochemical olarak, temel endüstriyel işlemleri için yoğun proses ısısı (tipik olarak 300–800°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. Petrokimya tesisleri, etilen, propilen ve diğer temel kimyasalları üretmek için hidrokarbonları çok yüksek sıcaklıklarda kraker — en ısı yoğun endüstriyel işlemlerden biridir.

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