(Shazand) Arak Petrochemical, Arak,Marzaki — Iran

(Shazand) Arak Petrochemical, Arak,Marzaki is a petrochemical plant in Iran. Its listed capacity is 306,000 t of ethylene. Petrochemical plants crack hydrocarbons at very high temperatures to produce ethylene, propylene and other building-block chemicals — one of the most heat-intensive industrial processes. It is operated by Atie Saba Investment Co. By capacity it ranks #6 among 7 petrochemical plants in Iran. It emits about 429,674 t CO₂e a year from Climate TRACE. That is 0.35% of the CO₂e from the 126 facilities in Iran that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 8% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-731908.

In context: how this facility compares

At 306,000 t of ethylene, (Shazand) Arak Petrochemical, Arak,Marzaki is below the median petrochemical plant in Iran (520,000 t of ethylene). Subsector: petrochemical-steam-cracking. As petrochemical plant, it requires high process heat (typically 300–800°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Petrochemical plants crack hydrocarbons at very high temperatures to produce ethylene, propylene and other building-block chemicals — one of the most heat-intensive industrial processes.

Local climate

(Shazand) Arak Petrochemical, Arak,Marzaki sits in a hot-summer Mediterranean continental climate zone (Köppen Dsa), at 34.0°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 1388 W/m² to ambient — roughly 1.07× 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.
