Mitsubishi Chemical Kashima, Kashima (Unit 2) — Japan

Mitsubishi Chemical Kashima, Kashima (Unit 2) is a petrochemical plant in Japan. Its listed capacity is 485,000 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 Mitsubishi Chemical Corp. By capacity it ranks #8 among 12 petrochemical plants in Japan. It emits about 681,894 t CO₂e a year from Climate TRACE. That is 0.42% of the CO₂e from the 105 facilities in Japan 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-731954.

In context: how this facility compares

At 485,000 t of ethylene, Mitsubishi Chemical Kashima, Kashima (Unit 2) is around the median petrochemical plant in Japan (493,000 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

Mitsubishi Chemical Kashima, Kashima (Unit 2) sits in a humid subtropical climate zone (Köppen Cfa), at 35.9°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 a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1352 W/m² to ambient — roughly 1.04× 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.
