NGA-Obio/Akpor_methanol — Nigeria

NGA-Obio/Akpor_methanol is a chemical plant in Nigeria. Its listed capacity is 656,304 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. By capacity it ranks #2 among 3 chemical plants in Nigeria. It emits about 219,041 t CO₂e a year from Climate TRACE. That is 0.66% of the CO₂e from the 25 facilities in Nigeria 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-33999017.

In context: how this facility compares

At 656,304 t of chemical, NGA-Obio/Akpor_methanol is around the median chemical plant in Nigeria (656,304 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

NGA-Obio/Akpor_methanol sits in a tropical monsoon climate zone (Köppen Am), at 4.8°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 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 1236 W/m² to ambient — roughly 0.95× 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.
