RefineryJapanCO₂ reported

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.

En contexte: comment cette installation se compare

À 70,000 BBL per day, Idemitsu Kosan Keihin Refinery est en dessous de la médiane des refinery en Japan (145,000 BBL per day). Son CO₂ par unité de capacité est approximativement 28% au-dessus de la médiane des refinery. Sous-secteur: oil-and-gas-refining. Comme refinery, elle nécessite une chaleur de procédé intensive (typiquement 200–600°C) pour ses opérations industrielles essentielles — chaleur qui doit être fournie par des chaudières, fours ou combustion directe, et les pertes par les récipients et tuyauteries non isolés représentent du combustible gaspillé. L'isolation modulaire amovible peut réduire ces pertes de 80–96%, refroidissant les surfaces à ≤45°C, avec des délais d'amortissement souvent inférieurs à 2 ans. Les raffineries chauffent, fractionnent et transforment chimiquement le pétrole brut en combustibles et matières premières pétrochimiques par distillation et craquage gourmands en énergie — extrêmement exigeants pour la génération de vapeur et la récupération de chaleur.
