Lusical, Companhia Lusitana De Cal Sa (Ci)

Lusical, Companhia Lusitana De Cal Sa (Ci) is a lime plant in Portugal. Its listed capacity is 538,759 t of lime. Lime plants calcine limestone in hot kilns at 800–900°C, and the hot quicklime must be handled in insulated vessels to prevent reaction with moisture. By capacity it ranks #4 among 5 lime plants in Portugal. It emits about 354,754 t CO₂e a year from Climate TRACE, roughly comparable to the annual emissions of 83k passenger cars.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-38467718.

In context: how this facility compares

At 538,759 t of lime, Lusical, Companhia Lusitana De Cal Sa (Ci) is below 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 — heat that must be supplied by boilers, furnaces or direct combustion, and losses through uninsulated vessels and piping represent wasted fuel. Removable modular insulation can cut those losses by 80–96%, surface-cooling equipment to ≤45°C, with payback often under 2 years. Lime plants calcine limestone in hot kilns at 800–900°C, and the hot quicklime must be handled in insulated vessels to prevent reaction with moisture.

Local climate

Lusical, Companhia Lusitana De Cal Sa (Ci) sits in a hot-summer Mediterranean climate zone (Köppen Csa), at 39.4°N in the northern hemisphere.

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

Site climate & environmental severity

The local climate sets how fast unprotected steel, protective coatings and the insulation on hot process equipment degrade at this site. It 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 1340 W/m² to ambient — roughly 1.03× the loss at a 20 °C reference; removable insulation recovers about 1273 W/m² of that. 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).

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.

Heat loss & insulation profile

For a lime plant, the main modular-insulation targets are kiln, preheater, hot-gas ducting, valves & dampers. Typical hot-surface ranges used for screening: 200–900 °C.

calcination-heavy like cement; fuel side only.

Indicative recoverable energy

A first-pass insulation screen suggests about 6,100 MWh/year of recoverable heat-loss reduction and about 2,100 t CO₂e/year of avoided emissions. Screening estimate scaled from installed process-heat projects and surface-temperature reduction data.

Safety & the no-regret first step

Start with a thermal survey of valves, flanges, doors and bends. Removable modular insulation keeps maintenance access open while lowering exposed-surface temperature and wasted heat.
