National Refinery Limited (NRL) Refinery — Pakistan

National Refinery Limited (NRL) Refinery is a refinery in Pakistan. Its listed capacity is 64,000 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 Attock Oil Company Ltd. By capacity it ranks #3 among 5 oil refineries in Pakistan. It emits about 226,268 t CO₂e a year from Climate TRACE. That is 0.42% of the CO₂e from the 55 facilities in Pakistan that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 59% below the national median for this sector.

In context: how this facility compares

At 64,000 BBL per day, National Refinery Limited (NRL) Refinery is around the median refinery in Pakistan (64,000 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

National Refinery Limited (NRL) Refinery sits in a hot desert climate zone (Köppen BWh), at 24.8°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 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 1242 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.
