Modellbasierte Rohmehlrezeptsteuerung für eine CO₂-optimierte Klinkerproduktion

The cement industry is facing the challenge of reducing its CO₂ footprint. One way to achieve this is through increased use of low-CO₂ alternative raw materials in clinker production. This article describes the development of an innovative process control system for optimizing raw meal production at the Wietersdorf cement plant. By employing inline analysis technologies and an optimization algorithm, various qualities of alternative raw materials can be simultaneously utilized to sustainably minimize CO₂ emissions. The tool is currently in the testing phase and has the potential to enhance product consistency while increasing the alternative raw material rate and as a result reducing the CO₂ footprint.
