発生源でトンを削減する

高温の産業設備? 熱損失を削減しましょう。

ボイラー、キルン、熱交換器、バルブ、蒸気ラインは継続的にエネルギーを失います。Inzonexは次を作ります: 特許取得済み(UK GB2508992.1)の取り外し可能モジュール式断熱 — 温度区分ごとに設計されたスナップ留めのカバー、汎用の既製の被覆ではなく:

熱損失を最大90%削減 断熱された表面から
表面温度 ≤45 °C — 作業者にとって接触安全(EN ISO 13732-1)
6倍速いメンテナンスアクセス 固定式の切断・溶接の被覆よりも — 数分で外して再装着、破壊なし
検査可能 — 断熱下腐食(CUI)の点検のために外れ、その後新品同様に再装着します(汎用の被覆はしばしば取り外しに耐えません)
典型的な投資回収 2年未満 (一部9〜11か月)

FAQ

質問

How many petrochemicals (steam cracking) facilities does Japan have with tracked emissions?

12 facilities carry satellite-based CO2 estimates in our dataset (Climate TRACE 2023), totalling ≈8,814,008 t CO2/yr.

What is the largest petrochemicals (steam cracking) emitter in Japan?

Keiyo Ethylene , Ichihara, Chiba — ≈970,117 t CO2/yr (est. 2023). Estimates are modelled, not verified declarations.

What would this CO2 cost at the EU price?

≈€682M per year at €77.4/t — indicative full-price value; actual cost depends on free allocation and the local instrument.
