Malaysian Refining Company Melaka II Refinery

Malaysian Refining Company Melaka II Refinery is a refinery in Malaysia. Its listed capacity is 170,000 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 Petroliam Nasional Bhd. By capacity it ranks #1 among 5 oil refineries in Malaysia. It emits about 1,479,426 t CO₂e a year from Climate TRACE. That is 3.4% of the CO₂e from the 39 facilities in Malaysia that have an emissions figure in IndustryAtlas.

In context: how this facility compares

At 170,000 BBL per day, Malaysian Refining Company Melaka II Refinery is well above the median refinery in Malaysia (124,000 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

Malaysian Refining Company Melaka II Refinery sits in a tropical rainforest climate zone (Köppen Af), at 2.3°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 an extreme marine/tropical environment (estimated ISO 9223 class CX — Extreme), with marine salt corrosion 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.
