Imperial Oil Sarnia Refinery

Imperial Oil Sarnia Refinery is a refinery in Canada with a reported capacity of 121,000 BBL per day. It processes crude oil into fuels and petrochemical feedstocks through distillation, cracking and reforming. It is operated by Exxon Mobil Corp. By capacity it ranks #7 of 18 oil refineries tracked in Canada. It emits about 1,625,111 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 378,814 cars. Its CO₂ per unit of capacity is about 59% above the median refinery.

Bağlamda: bu tesis nasıl karşılaştırılır

121,000 BBL per day'de, Imperial Oil Sarnia Refinery Canada'daki refinery'lerin medyanı yaklaşık 112,000 BBL per day'dir. Kapasite başına CO₂'si refinery'nin medyanı üstünde kabaca 35%'dir. Alt sektör: oil-and-gas-refining. refinery olarak, temel endüstriyel işlemleri için yoğun proses ısısı (tipik olarak 200–600°C) gerektirir — kazanlar, fırınlar veya doğrudan yanma ile sağlanması gereken ısı, ve izolasyon yapılmamış kaplar ve boruların kayıpları harcanan yakıtı temsil eder. Modüler çıkarılabilir yalıtım bu kayıpları %80–96 oranında azaltabilir, yüzeyleri ≤45°C'ye soğutabilir, geri ödeme süresi genellikle 2 yıldan azdır. Rafineriler, enerji yoğun destilasyon ve kraking yoluyla ham petrolü yakıtlara ve petrokimya hammaddelerine ısıtır, fraksiyonlar ve kimyasal olarak dönüştürür — buhar üretimi ve ısı geri kazanımı için son derece taleplidir.

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 52,000 MWh/yr (≈ 10,000 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.

External climate finance your country can access

Domestic energy-efficiency grants are limited here; industrial decarbonisation is mainly funded externally:

• Japan JCM (Joint Crediting Mechanism) — Japan co-finances diffusion of decarbonising tech incl. INDUSTRIAL ENERGY EFFICIENCY in partner countries, in exchange for carbon credits. Channels: MOEJ model projects, ADB trust funds, NEDO demonstrations.
• UK International Climate Finance (ICF / ODA) — ~GBP 6bn ODA over 3 yrs; industrial-decarbonisation flows via Climate Investment Funds (CIF) - Clean Technology Fund.
• Green Climate Fund (GCF) + ADB / World Bank / UNIDO — Concessional finance & grants for industrial energy efficiency. E.g. GCF $200M ADB-led India Green Finance Facility; World Bank FP071 'Scaling Up Energy Efficiency for Industrial Enterprises in Vietnam'; ASEAN ACGF energy-efficiency revolving funds incl. SMEs.
