emissions from the cement industry

May 09, 2012 · Cement Emissions. The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions. The direct emissions of cement occur through a chemical process called calcination

cement production - an overview | sciencedirect topics

Cement production is a thermal energy intensive process, which requires heating solid particles up to 1450°C and cooling it down. The process generates hot and CO 2 rich exhaust streams. Fin order to study energy efficiency of the process, authors like Mujumdar et al. (2006 , 2007) developed detail models of process units, while others

Summary of production process. Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of
