Cement Plant in Benin. Approximate location 7.14185, 2.54525.

Cement PlantBeninCO₂ reported

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.

En contexte: comment cette installation se compare

À 1,700,000 t of cement, Ouinhi Cement Plant est autour de la médiane des cement plant en Benin (1,700,000 t of cement). Sous-secteur: cement. Comme cement plant, elle nécessite une chaleur de procédé intensive (typiquement 800–1400°C) pour ses opérations industrielles essentielles — chaleur qui doit être fournie par des chaudières, fours ou combustion directe, et les pertes par les récipients et tuyauteries non isolés représentent du combustible gaspillé. L'isolation modulaire amovible peut réduire ces pertes de 80–96%, refroidissant les surfaces à ≤45°C, avec des délais d'amortissement souvent inférieurs à 2 ans. Les cimenteries chauffent le calcaire à 1.400°C dans des fours rotatifs — l'un des processus industriels les plus chauds — et doivent contrôler la température avec précision sur toute la longueur du four.
