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.

Em contexto: como esta instalação se compara

Com 519,000 BBL per day, S-Oil Onsan Refinery é bem acima de a mediana de refinery em South Korea (256,000 BBL per day). Seu CO₂ por unidade de capacidade é aproximadamente 111% acima de a mediana de refinery. 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.
