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.

Im Kontext: wie sich diese Anlage vergleicht

Bei 70,000 BBL per day ist Idemitsu Kosan Keihin Refinery unter dem Medianwert von refinery in Japan (145,000 BBL per day). Sein CO₂ pro Kapazitätseinheit liegt ungefähr 28% über dem Medianwert von refinery. Untersektor: oil-and-gas-refining. Als refinery benötigt es intensive Prozesswärme (typischerweise 200–600°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. Raffinerien wärmen auf, fraktionieren und chemisch transformieren Rohöl durch energieintensive Destillation und Cracken in Brennstoffe und petrochemische Rohstoffe — extrem anspruchsvoll für Dampfzeugung und Wärmenutzung.
