CNOOC Huizhou Refinery — China
Refinery in China. Approximate location 22.75224, 114.59056.
RefineryChinaCO₂ estimate (modelled)
CNOOC Huizhou Refinery is a refinery in China. Its listed capacity is 440,000 BBL per day. Refineries heat, fractionate and chemically transform crude oil into fuels and petrochemical feedstocks through energy-intensive distillation and cracking — extremely demanding on steam generation and heat recovery. It is operated by CNOOC. By capacity it ranks #2 among 65 oil refineries in China. It emits about 5,467,956 t CO₂e a year from Climate TRACE. That is 0.21% of the CO₂e from the 1,485 facilities in China that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 44% above the national median for this sector.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3143820.

In context: how this facility compares
At 440,000 BBL per day, CNOOC Huizhou Refinery is well above the median refinery in China (90,450 BBL per day). Subsector: oil-and-gas-refining. As refinery, it requires high process heat (typically 200–600°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Refineries heat, fractionate and chemically transform crude oil into fuels and petrochemical feedstocks through energy-intensive distillation and cracking — extremely demanding on steam generation and heat recovery.

Carbon cost and Scope 1 emissions
At its reported 5.5M t CO₂e/yr (Scope 1), CNOOC Huizhou Refinery carries no domestic carbon price, and its products are not CBAM-covered goods, so there is no border-carbon liability. At the EU ETS reference price (€75/t) the emissions carry an indicative carbon value of €412M/yr.

Local climate
CNOOC Huizhou Refinery sits in a humid subtropical (dry winter) climate zone (Köppen Cwa), at 22.8°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 1282 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.
