Refisan S.A. San Lorenzo Refinery — Argentina

Refisan S.A. San Lorenzo Refinery is a refinery in Argentina. Its listed capacity is 50,000 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 Refineria San Lorenzo SA. By capacity it ranks #4 among 7 oil refineries in Argentina. It emits about 510,748 t CO₂e a year from Climate TRACE. That is 2.4% of the CO₂e from the 33 facilities in Argentina that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 19% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3143727.

In context: how this facility compares

At 50,000 BBL per day, Refisan S.A. San Lorenzo Refinery is around the median refinery in Argentina (50,000 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

Refisan S.A. San Lorenzo Refinery sits in a humid subtropical climate zone (Köppen Cfa), at 32.7°S in the southern hemisphere.

Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1322 W/m² to ambient — roughly 1.02× 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.
