IOCL Bongaigaon Refinery — India
Refinery in India. Approximate location 26.51502, 90.53294.
RefineryIndiaCO₂ estimate (modelled)
IOCL Bongaigaon Refinery is a refinery in India. Its listed capacity is 54,000 BBL per day. Refineries heat, fractionate and chemically transform crude oil into fuels and petrochemical feedstocks through energy-intensive distillation and cracking — extremely demanding on steam generation and heat recovery. It is operated by Indian Oil Corporation Ltd. By capacity it ranks #14 among 17 oil refineries in India. It emits about 375,686 t CO₂e a year from Climate TRACE. That is 0.08% of the CO₂e from the 297 facilities in India that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 19% below the national median for this sector.

In context: how this facility compares
At 54,000 BBL per day, IOCL Bongaigaon Refinery is below the median refinery in India (161,000 BBL per day). Subsector: oil-and-gas-refining. As refinery, it requires high process heat (typically 200–600°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Refineries heat, fractionate and chemically transform crude oil into fuels and petrochemical feedstocks through energy-intensive distillation and cracking — extremely demanding on steam generation and heat recovery.

Local climate
IOCL Bongaigaon Refinery sits in a humid subtropical (dry winter) climate zone (Köppen Cwa), at 26.5°N in the northern hemisphere.
Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1255 W/m² to ambient — roughly 0.96× the loss at a 20 °C reference. Reference-surface calculation at a 150 °C surface from WorldClim climate normals (ASTM C680 / ISO 12241) — an indicative per-climate comparison, not a measurement of this site’s specific equipment. Open method dataset: DOI 10.5281/zenodo.20787408 (CC BY 4.0).
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
