Hengyi Pulau Muara Besar Refinery — Brunei Darussalam
Refinery in Brunei Darussalam. Approximate location 4.99826, 115.11841.
RefineryBrunei DarussalamCO₂ estimate (modelled)
Hengyi Pulau Muara Besar Refinery is a refinery in Brunei Darussalam. Its listed capacity is 175,000 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 Zhejiang Hengli Group. By capacity it ranks #1 among 2 oil refineries in Brunei Darussalam. It emits about 2,360,689 t CO₂e a year from Climate TRACE. That is 88% of the CO₂e from the 3 facilities in Brunei Darussalam that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 57% above the national median for this sector.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3143763.

In context: how this facility compares
At 175,000 BBL per day, Hengyi Pulau Muara Besar Refinery is around the median refinery in Brunei Darussalam (175,000 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
Hengyi Pulau Muara Besar Refinery sits in a tropical rainforest climate zone (Köppen Af), at 5.0°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 1228 W/m² to ambient — roughly 0.94× 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.
