ONGC Petro Additions Limited (OPaL), Dahej, Gujarat

ONGC Petro Additions Limited (OPaL), Dahej, Gujarat is a petrochemical in India with a reported capacity of 1,100,000 t of ethylene. It cracks hydrocarbon feedstocks into building-block chemicals such as ethylene and propylene. It is operated by Oil and Natural Gas Corporation Ltd. By capacity it ranks #3 of 11 petrochemical plants tracked in India. It emits about 1,909,265 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 445,050 cars. Its CO₂ per unit of capacity is about 29% above the median petrochemical.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-40691244.

В контексте: как это предприятие сравнивается

На мощности 1,100,000 t of ethylene ONGC Petro Additions Limited (OPaL), Dahej, Gujarat — это значительно выше медианная petrochemical в India (800,000 t of ethylene). Его выброс CO₂ на единицу мощности примерно на 31% выше медианной petrochemical. Подсектор: petrochemical-steam-cracking. Как petrochemical, оно требует высокотемпературного технологического тепла (обычно 300–800°C) для основных промышленных операций — тепла, которое должно подаваться котлами, печами или прямым сжиганием, и потери через неизолированные сосуды и трубопроводы представляют потраченное впустую топливо. Съёмная модульная теплоизоляция может снизить эти потери на 80–96%, охладив поверхность оборудования до ≤45°C, с окупаемостью часто менее 2 лет. Нефтехимические заводы крекируют углеводороды при очень высоких температурах для производства этилена, пропилена и других базовых химикатов — один из самых теплоёмких промышленных процессов.

Сравнение производительности и интенсивности CO₂ рассчитано на основе данных промышленных объектов Climate TRACE; роль сектора основана на инженерных справочниках.
