S-Oil Onsan Refinery

S-Oil Onsan Refinery is a refinery in South Korea with a reported capacity of 519,000 BBL per day. It processes crude oil into fuels and petrochemical feedstocks through distillation, cracking and reforming. It is operated by Saudi Arabian Oil Co. By capacity it ranks #3 of 9 oil refineries tracked in South Korea. It emits about 6,196,517 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 1,444,410 cars. Its CO₂ per unit of capacity is about 41% above the median refinery.

En contexto: cómo se compara esta instalación

Con 519,000 BBL per day, S-Oil Onsan Refinery está muy por encima de la mediana de refinery en South Korea (256,000 BBL per day). Su CO₂ por unidad de capacidad es aproximadamente 111% por encima de la mediana de refinery. Subsector: oil-and-gas-refining. Como refinery, requiere calor de proceso intenso (típicamente 200–600°C) para sus operaciones industriales centrales — calor que debe ser suministrado por calderas, hornos o combustión directa, y las pérdidas a través de recipientes y tuberías sin aislar representan combustible desperdiciado. El aislamiento modular desmontable puede reducir esas pérdidas en un 80–96%, enfriando superficies a ≤45°C, con amortización a menudo inferior a 2 años. Las refinerías calientan, fraccionan y transforman químicamente el petróleo crudo en combustibles y materias primas petroquímicas mediante destilación y craqueo que consumen mucha energía — extremadamente exigentes en generación de vapor y recuperación de calor.
