RefineryIraqCO₂ estimate (modelled)
INOC Diwaniya Refinery is a refinery in Iraq. Its listed capacity is 20,000 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 Iraq National Oil Co. By capacity it ranks #12 among 14 oil refineries in Iraq. It emits about 47,189 t CO₂e a year from Climate TRACE, roughly comparable to the annual emissions of 11k passenger cars. Its CO₂ per unit of capacity is 73% below the national median for this sector.

At 20,000 BBL per day, INOC Diwaniya Refinery is below the median refinery in Iraq (40,000 BBL per day). Subsector: oil-and-gas-refining. As refinery, it requires high process heat (typically 200–600°C) for its core industrial operations — 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. 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.

At its reported 47k t CO₂e/yr (Scope 1), INOC Diwaniya Refinery carries no domestic carbon price; refinerys are not a CBAM-covered good, so there is no border-carbon liability. At the EU ETS reference price (€75/t) the emissions carry an indicative carbon value of €3.6M/yr. The fastest decarbonization lever is energy efficiency: eliminating heat loss on hot equipment (removable insulation, steam & waste-heat recovery) typically cuts 2–5% of fuel-related CO₂ — here ≈944 t–2k t/yr, worth €71k–€178k, with payback up to 2 years. No domestic carbon price — but cement, steel, aluminium, fertilizer and hydrogen exported to the EU face CBAM at €75/t (rising to 100% by 2034).

INOC Diwaniya Refinery sits in a hot desert climate zone (Köppen BWh), at 31.5°N in the northern hemisphere.
Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
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 benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1259 W/m² to ambient — roughly 0.97× the loss at a 20 °C reference; removable insulation recovers about 1196 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.

For a refinery, the main modular-insulation targets are crude & vacuum distillation columns, fired heaters, heat exchangers, steam lines, valves & flanges. Typical hot-surface ranges used for screening: 150–550 °C.
A first-pass insulation screen suggests about 31,000 MWh/year of recoverable heat-loss reduction and about 6,200 t CO₂e/year of avoided emissions. Screening estimate scaled from installed process-heat projects and surface-temperature reduction data.

Screening calculation from facility class, capacity and open emissions/energy context. Engineering survey required before procurement.
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.
