Ouinhi Cement Plant

Ouinhi Cement Plant is a cement plant in Benin with a reported capacity of 1,700,000 t of cement. It burns limestone in high-temperature rotary kilns to make clinker and cement. It is operated by Nouvelle Cimenterie du Benin SA. By capacity it ranks #1 of 2 cement plants tracked in Benin. It emits about 739,900 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 172,471 cars. Its CO₂ per unit of capacity is about 21% above the median cement plant.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1895178.

En contexto: cómo se compara esta instalación

Con 1,700,000 t of cement, Ouinhi Cement Plant está alrededor de la mediana de cement plant en Benin (1,700,000 t of cement). Subsector: cement. Como cement plant, requiere calor de proceso intenso (típicamente 800–1400°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 de cemento calientan piedra caliza a 1.400°C en hornos rotativos — uno de los procesos industriales más calientes — y deben controlar la temperatura con precisión en toda la longitud del horno.
