Hilcorp Energy Prudhoe Bay Refinery — United States
Refinery in United States. Approximate location 70.25359, -148.37813.
RefineryUnited StatesCO₂ estimate (modelled)
Hilcorp Energy Prudhoe Bay Refinery is a refinery in United States. Its listed capacity is 6,500 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 Hilcorp Energy Co. By capacity it ranks #114 among 119 oil refineries in United States. It emits about 45,092 t CO₂e a year from Climate TRACE. Its CO₂ per unit of capacity is 19% below the national median for this sector.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1753384.

In context: how this facility compares
At 6,500 BBL per day, Hilcorp Energy Prudhoe Bay Refinery is below the median refinery in United States (89,200 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
Hilcorp Energy Prudhoe Bay Refinery sits in a Mediterranean subarctic climate zone (Köppen Dsc), at 70.3°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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1611 W/m² to ambient — roughly 1.24× 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.
