CEMEX CEMENT PLANT (Alicante, Spain)
Urban sludge facility with a 60,000 t/year capacity equipped with two driers with a capacity of 3,000 l/h of evaporated water per unit. The heat necessary for the drying process is generated using hot water (recovery of residual energy from the cement plant). Installation completed in 2011.
This facility is located at CEMEX’s San Vicente del Raspeig cement factory and is designed to be an external treatment centre (multi-management) for sludge from various treatment centres located in Alicante and its surrounding area.
The main innovation is that the heat used for drying is excess heat recovered from the cement factory.
This cuts down on CO2, as primary energy is not used in the drying process. The dried sludge can be used for agriculture or be sent to the cement plant for energy use.
