Fuji Oil Sodegaura Refinery

Fuji Oil Sodegaura Refinery is a refinery in Japan with a reported capacity of 143,000 BBL per day. It processes crude oil into fuels and petrochemical feedstocks through distillation, cracking and reforming. It is operated by Fuji Oil Company Ltd. By capacity it ranks #11 of 21 oil refineries tracked in Japan. It emits about 736,584 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 171,698 cars. Its CO₂ per unit of capacity is about 39% below the median refinery.

在上下文中：该设施如何比较

在143,000 BBL per day时，Fuji Oil Sodegaura Refinery是Japan中refinery的中位数约 145,000 BBL per day。 其单位容量的CO₂约为refinery中位数的低于 40%。 子部门：oil-and-gas-refining。 作为refinery，它需要强烈的工艺热量（通常200–600°C）来进行其核心工业操作——必须通过锅炉、炉或直接燃烧供应的热量，通过未隔热的容器和管道的损失代表浪费的燃料。可拆卸模块化绝缘可以将这些损失减少80-96%，将表面冷却至≤45°C，投资回收期通常不到2年。 炼油厂通过能源密集型蒸馏和裂化加热、分馏和化学转化原油为燃料和石化原料——对蒸汽发生和热回收要求极高。

Heat loss & insulation profile

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.

Indicative recoverable energy

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 40,000 MWh/yr (≈ 8,000 t CO₂/yr) — scaled to this site's reported CO₂ within its sector. Bare or damaged surfaces recover several times more.

See Inzonex insulation → Estimate your site →

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.

Safety & the no-regret first step

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.

Japan: funding & obligation

Funding. Subsidies to cut upfront cost of energy-saving equipment for industry/commercial; some tied to 'specified business operator' status + S/A benchmark class.

Obligation. Factories/operators with large energy use are designated 'specified business operators': must appoint energy managers, report, and file mid-to-long-term efficiency plans. (applies as a rule above the stated threshold — we don't hold this site's metered energy use).
