ExxonMobil Singapore Refinery

ExxonMobil Singapore Refinery is a refinery in Singapore. Its listed capacity is 592,000 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 Exxon Mobil Corp. By capacity it ranks #1 among 3 oil refineries in Singapore. It emits about 5,634,555 t CO₂e a year from Climate TRACE. That is 30% of the CO₂e from the 7 facilities in Singapore that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 11% above the national median for this sector.

In context: how this facility compares

At 592,000 BBL per day, ExxonMobil Singapore Refinery is well above the median refinery in Singapore (290,000 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.

Local climate

ExxonMobil Singapore Refinery sits in a tropical rainforest climate zone (Köppen Af), at 1.3°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 1231 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.
