Alternative Cement Would Save 6.69 Gigatons of Carbon by
Alternative cement places #36 on Drawdown''s list of climate solutions, with the potential to avoid 6.69 gigatons of atmospheric carbon dioxide by 2050. The shift would save US$174 billion, because such alternatives ultimately last longer. The trouble with conventional cement, Drawdown notes, is that fundamental to its strength is calcium oxide, produced by kilnroasting a mixture of
Advanced Process Control of kilns in the cement industry
The rotary cement kiln process is intrinsically unstable, there are long time delays and large perturbations acting on it. The control problem consists of maintaining a given temperature profile along the kiln plus obtaining good burning conditions. 2.0% energy saving, 2.0% production increase. Turkey. Increased efficiency with highquality
Being an energy intensive industry, this segment of industry typically accounts for 50–60% of total production costs . The typical electrical energy consumption of a modern cement plant is about 110–120 kWh per ton of cement . It has been proven that a thermal energy saving potential of 0.25–0.345 GJ/t, an

Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energyconsuming and greenhousegas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing
The production of cement is an energyintensive process. Annually the cement industry spends over $1 billion energy purchases. The production of cement results in the emission of carbon dioxide from both the consumption of fuels and from the calcination of limestone. This report briefly describes the various stages in the cement production process.
