Industrial : Optimization for the Cement Industry

Cement Kiln Optimization Controlling a cement rotary kiln is a very difficult task. The process is intrinsically unstable and there are long time delays and large pertur-bations acting on it. Only a perfect mix of expe-rience, deep knowledge, mathematical tech-niques and state-of-the-art software can achieve optimal behaviour over long periods ...

Energy optimization in cement manufacturing

Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further

Parametric Studies of Cement Production Processes

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.
