ExxonMobil Chemical Co. , Mossmorran Fife — United Kingdom

ExxonMobil Chemical Co. , Mossmorran Fife is a petrochemical plant in United Kingdom. Its listed capacity is 770,000 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 Exxon Mobil Corp. It emits about 696,425 t CO₂e a year from Climate TRACE. That is 2.7% of the CO₂e from the 44 facilities in United Kingdom that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 31% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-18648379.

In context: how this facility compares

At 770,000 t of ethylene, ExxonMobil Chemical Co. , Mossmorran Fife is around the median petrochemical plant in United Kingdom (770,000 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

ExxonMobil Chemical Co. , Mossmorran Fife sits in a temperate oceanic climate zone (Köppen Cfb), at 56.1°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 1417 W/m² to ambient — roughly 1.09× 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.
