GS Caltex Yeosu, Yeochun — South Korea

GS Caltex Yeosu, Yeochun is a petrochemical plant in South Korea. Its listed capacity is 750,000 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 Chevron Phillips Chemical. By capacity it ranks #8 among 8 petrochemical plants in South Korea. It emits about 1,017,159 t CO₂e a year from Climate TRACE. That is 0.66% of the CO₂e from the 51 facilities in South Korea that have an emissions figure in IndustryAtlas.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-731976.

In context: how this facility compares

At 750,000 t of ethylene, GS Caltex Yeosu, Yeochun is below the median petrochemical plant in South Korea (1,230,000 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

GS Caltex Yeosu, Yeochun sits in a humid subtropical (dry winter) climate zone (Köppen Cwa), at 34.9°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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1363 W/m² to ambient — roughly 1.05× 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.
