  • Cement production - Flue Gas cleaning | Carmeuse

    For many cement producers, meeting legislated standards for acid gases, particularly SO2, means adding an extra step in the control system. The cost of this added step can be minimized by the recycling of the by-product in the cement production. This eliminates the cost of by-product disposal. When selecting a flue gas cleaning solution, reliability, ease of use and cost efficiency are the key ...
