PetrochemicalUnited StatesCO₂ estimate (modelled)
Chevron Phillips Chemical, Sweeny,Tex is a petrochemical plant in United States. Its listed capacity is 1,950,000 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 #5 among 26 petrochemical plants in United States. It emits about 2,642,544 t CO₂e a year from Climate TRACE. That is 0.47% of the CO₂e from the 1,910 facilities in United States that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-18648310.

In context: how this facility compares
At 1,950,000 t of ethylene, Chevron Phillips Chemical, Sweeny,Tex is well above the median petrochemical plant in United States (1,134,000 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
Chevron Phillips Chemical, Sweeny,Tex sits in a humid subtropical climate zone (Köppen Cfa), at 29.1°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 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 1292 W/m² to ambient — roughly 0.99× 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.
