Mariel Cement Plant

Mariel Cement Plant is a cement plant in Cuba with a reported capacity of 1,000,000 t of cement. It burns limestone in high-temperature rotary kilns to make clinker and cement. It is operated by Empresa Mixta Cementos Curazao SA. By capacity it ranks #2 of 4 cement plants tracked in Cuba. It emits about 330,718 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 77,090 cars. Its CO₂ per unit of capacity is about 8% below the median cement plant.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32438302.

En contexto: cómo se compara esta instalación

Con 1,000,000 t of cement, Mariel Cement Plant está alrededor de la mediana de cement plant en Cuba (1,000,000 t of cement). Su CO₂ por unidad de capacidad es aproximadamente 9% por debajo de la mediana de cement plant. 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.
