STAR Aliaga Oil Refinery — Türkiye

STAR Aliaga Oil Refinery is a refinery in Türkiye. Its listed capacity is 240,000 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 State Oil Company of Azerbaijan Republic. By capacity it ranks #1 among 5 oil refineries in Türkiye. It emits about 2,720,977 t CO₂e a year from Climate TRACE. That is 3.3% of the CO₂e from the 94 facilities in Türkiye that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 32% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3144143.

In context: how this facility compares

At 240,000 BBL per day, STAR Aliaga Oil Refinery is around the median refinery in Türkiye (226,000 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

STAR Aliaga Oil Refinery sits in a hot-summer Mediterranean climate zone (Köppen Csa), at 38.8°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 1342 W/m² to ambient — roughly 1.03× 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.
