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.

Nel contesto: come si confronta questo impianto

Con 1,700,000 t of cement, Ouinhi Cement Plant è attorno a la mediana di cement plant in Benin (1,700,000 t of cement). Sottosettore: cement. Come cement plant, richiede calore di processo intenso (tipicamente 800–1400°C) per le sue operazioni industriali essenziali — calore che deve essere fornito da caldaie, forni o combustione diretta, e le perdite attraverso recipienti e tubazioni non isolati rappresentano carburante sprecato. L'isolamento modulare removibile può ridurre queste perdite dell'80–96%, raffreddando superfici a ≤45°C, con payback spesso inferiore a 2 anni. Le cementerie riscaldano il calcare a 1.400°C in forni rotativi — uno dei processi industriali più caldi — e devono controllare la temperatura con precisione lungo l'intera lunghezza del forno.
