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.

Im Kontext: wie sich diese Anlage vergleicht

Bei 618,000 t of ethylene ist Resonac Oita, KK Oita deutlich über dem Medianwert von petrochemical in Japan (493,000 t of ethylene). Untersektor: petrochemical-steam-cracking. Als petrochemical benötigt es intensive Prozesswärme (typischerweise 300–800°C) für seinen Kernbetrieb — Wärme, die durch Dampfkessel, Öfen oder direkte Verbrennung geliefert werden muss, und Verluste durch ungedämmte Behälter und Rohrleitungen stellen verschwendeten Brennstoff dar. Modulare abnehmbare Dämmung kann diese Verluste um 80–96% senken, Oberflächen auf ≤45°C kühlen, mit Amortisationszeiten oft unter 2 Jahren. Petrochemische Anlagen spalten Kohlenwasserstoffe bei sehr hohen Temperaturen auf, um Ethylen, Propylen und andere Basischemikalien zu erzeugen — einer der wärmeintensivsien Industrieprozesse.
