Tangshan (Nanbao) Chemical Complex — China

Tangshan (Nanbao) Chemical Complex is a chemical plant in China. Its listed capacity is 3,084,430 t of chemical. Chemical plants produce a wide range of industrial and specialty chemicals, many requiring precise temperature control and sustained heat input for reactions and separations. It is operated by Tangshan Sanyou Chemical Industries Co Ltd. By capacity it ranks #8 among 125 chemical plants in China. It emits about 1,020,182 t CO₂e a year from Climate TRACE. That is 0.04% of the CO₂e from the 1,485 facilities in China that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 77% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-45257188.

In context: how this facility compares

At 3,084,430 t of chemical, Tangshan (Nanbao) Chemical Complex is well above the median chemical plant in China (532,416 t of chemical). Subsector: chemicals. As chemical plant, it requires high process heat (typically 100–500°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Chemical plants produce a wide range of industrial and specialty chemicals, many requiring precise temperature control and sustained heat input for reactions and separations.

Local climate

Tangshan (Nanbao) Chemical Complex sits in a monsoon hot-summer continental climate zone (Köppen Dwa), at 39.2°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 1383 W/m² to ambient — roughly 1.06× 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.
