RefineryCubaCO₂ reported
CUPET Hermanos Diaz Refinery is a refinery in Cuba with a reported capacity of 22,000 BBL per day. It processes crude oil into fuels and petrochemical feedstocks through distillation, cracking and reforming. It is operated by Cuba Petróleo SA. By capacity it ranks #2 of 3 oil refineries tracked in Cuba. It emits about 94,476 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 22,022 cars. Its CO₂ per unit of capacity is about 49% below the median refinery.

Com 22,000 BBL per day, CUPET Hermanos Diaz Refinery é em torno de a mediana de refinery em Cuba (22,000 BBL per day). Subsetor: oil-and-gas-refining. Como refinery, requer calor de processo intenso (tipicamente 200–600°C) para suas operações industriais centrais — calor que deve ser fornecido por caldeiras, fornos ou combustão direta, e as perdas através de vasos e tubulações não isolados representam combustível desperdiçado. O isolamento modular removível pode reduzir essas perdas em 80–96%, esfriando superfícies a ≤45°C, com payback geralmente inferior a 2 anos. As refinarias aquecem, fracionam e transformam quimicamente o petróleo bruto em combustíveis e matérias-primas petroquímicas através de destilação e craqueamento que consomem muita energia — extremamente exigentes em geração de vapor e recuperação de calor.

A refinery like this runs hot equipment that sheds heat continuously: crude & vacuum distillation columns, fired heaters, heat exchangers, steam lines, valves & flanges (surface/process temperatures around 150–550 °C). These surfaces lose energy to the air year-round; removable modular insulation cuts that loss, brings outer surfaces to ≤45 °C, and unclips for inspection.
On an already-insulated site (pipes & valves in cladding / jackets), closing the remaining gaps, flanges and damaged sections and switching to removable covers indicatively recovers about 31,000 MWh/yr (≈ 6,200 t CO₂/yr) — scaled to this site's reported CO₂ within its sector. Bare or damaged surfaces recover several times more.

Indicative, not a measurement. Conservative floor for an already-insulated plant; a TIPCHECK on-site audit gives a measured figure. Industry context: EiiF TIPCHECK — industrial insulation can save ~14 Mtoe/yr in EU, payback typically <2 years.
Bare hot surfaces here exceed the touch-safe limit (EN ISO 13732-1); insulation to ≤45 °C is a worker-safety and compliance win. And before electrification, fuel-switching or CCS, eliminating surface heat loss is the cheapest, fastest, lowest-risk step — audit the bare spots first, rip-and-replace later.
