Resonac Oita, KK Oita

Resonac Oita, KK Oita is a petrochemical in Japan with a reported capacity of 618,000 t of ethylene. It cracks hydrocarbon feedstocks into building-block chemicals such as ethylene and propylene. It is operated by Resonac . By capacity it ranks #3 of 12 petrochemical plants tracked in Japan. It emits about 868,888 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 202,538 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-731958.

En contexte: comment cette installation se compare

À 618,000 t of ethylene, Resonac Oita, KK Oita est bien au-dessus de la médiane des petrochemical en Japan (493,000 t of ethylene). Sous-secteur: petrochemical-steam-cracking. Comme petrochemical, elle nécessite une chaleur de procédé intensive (typiquement 300–800°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 usines pétrochimiques craquent les hydrocarbures à des températures très élevées pour produire l'éthylène, le propylène et d'autres produits chimiques de base — l'un des processus industriels les plus intensifs en chaleur.
