Fábrica Cibra-Pataias (Ci) — Portugal

Fábrica Cibra-Pataias (Ci) is a lime plant in Portugal. Its listed capacity is 702,065 t of lime. Lime plants calcine limestone in kilns at 800–900°C; the quicklime they produce reacts with moisture and has to be kept dry. By capacity it ranks #3 among 5 lime plants in Portugal. It emits about 462,286 t CO₂e a year from Climate TRACE. That is 3.1% of the CO₂e from the 29 facilities in Portugal that have an emissions figure in IndustryAtlas.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-38467604.

In context: how this facility compares

At 702,065 t of lime, Fábrica Cibra-Pataias (Ci) is around the median lime plant in Portugal (702,065 t of lime). Subsector: lime. As lime plant, it requires high process heat (typically 600–900°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Lime plants calcine limestone in kilns at 800–900°C; the quicklime they produce reacts with moisture and has to be kept dry.

Local climate

Fábrica Cibra-Pataias (Ci) sits in a warm-summer Mediterranean climate zone (Köppen Csb), at 39.7°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 marine corrosion the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1354 W/m² to ambient — roughly 1.04× 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.
