IOCL Digboi Refinery

IOCL Digboi Refinery is a refinery in India with a reported capacity of 13,000 BBL per day. It processes crude oil into fuels and petrochemical feedstocks through distillation, cracking and reforming. It is operated by Indian Oil Corporation Ltd. By capacity it ranks #20 of 22 oil refineries tracked in India. It emits about 227,985 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 53,143 cars. Its CO₂ per unit of capacity is about 108% above the median refinery.

En contexte: comment cette installation se compare

À 13,000 BBL per day, IOCL Digboi Refinery est en dessous de la médiane des refinery en India (210,000 BBL per day). Son CO₂ par unité de capacité est approximativement 25% 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.
