Ryukyu Cement Nago Cement Plant

Ryukyu Cement Nago Cement Plant is a cement plant in Japan with a reported capacity of 650,000 t of cement. It burns limestone in high-temperature rotary kilns to make clinker and cement. It is operated by Ryukyu Cement Co Ltd. By capacity it ranks #26 of 27 cement plants tracked in Japan. It emits about 245,696 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 57,272 cars. Its CO₂ per unit of capacity is about 5% above the median cement plant.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1897354.

Em contexto: como esta instalação se compara

Com 650,000 t of cement, Ryukyu Cement Nago Cement Plant é abaixo de a mediana de cement plant em Japan (1,890,000 t of cement). Subsetor: cement. Como cement plant, requer calor de processo intenso (tipicamente 800–1400°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 cimenteiras aquecem calcário a 1.400°C em fornos rotativos — um dos processos industriais mais quentes — e devem controlar a temperatura com precisão em todo o comprimento do forno.
