Celbi Caima Dissolving Pulp Mill

Celbi Caima Dissolving Pulp Mill is a pulp & paper mill in Portugal. Its listed capacity is 115,000 t of pulp & paper. Pulp and paper mills generate their own steam for the pulping process and paper dryers, running large-scale boiler systems where heat loss directly reduces efficiency. It is operated by The Navigator Co. By capacity it ranks #5 among 6 pulp & paper mills in Portugal. It emits about 62,377 t CO₂e a year from Climate TRACE, roughly comparable to the annual emissions of 15k passenger cars.

In context: how this facility compares

At 115,000 t of pulp & paper, Celbi Caima Dissolving Pulp Mill is below the median pulp & paper mill in Portugal (333,000 t of pulp & paper). Subsector: pulp-and-paper. As pulp & paper mill, it requires high process heat (typically 150–250°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. Pulp and paper mills generate their own steam for the pulping process and paper dryers, running large-scale boiler systems where heat loss directly reduces efficiency.

Local climate

Celbi Caima Dissolving Pulp Mill sits in a hot-summer Mediterranean climate zone (Köppen Csa), at 39.5°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 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 1337 W/m² to ambient — roughly 1.03× the loss at a 20 °C reference; removable insulation recovers about 1270 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 pulp & paper mill, the main modular-insulation targets are digesters, dryers, evaporators, steam lines, hot-water systems. Typical hot-surface ranges used for screening: 80–200 °C.

Indicative recoverable energy

A first-pass insulation screen suggests about 4,600 MWh/year of recoverable heat-loss reduction and about 920 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.
