Idemitsu Kosan Chiba, Chiba

Idemitsu Kosan Chiba, Chiba is a petrochemical in Japan with a reported capacity of 414,000 t of ethylene. It cracks hydrocarbon feedstocks into building-block chemicals such as ethylene and propylene. By capacity it ranks #11 of 12 petrochemical plants tracked in Japan. It emits about 582,070 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 135,681 cars. Its CO₂ per unit of capacity is about 5% above the median petrochemical.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-731950.

En contexto: cómo se compara esta instalación

Con 414,000 t of ethylene, Idemitsu Kosan Chiba, Chiba está alrededor de la mediana de petrochemical en Japan (493,000 t of ethylene). Subsector: petrochemical-steam-cracking. Como petrochemical, requiere calor de proceso intenso (típicamente 300–800°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 plantas petroquímicas agrietan hidrocarburos a temperaturas muy altas para producir etileno, propileno y otros químicos básicos — uno de los procesos industriales más intensivos en calor.
