Analysis on the CO₂ Emission of Calcium Carbide Sludge as Secondary Raw Material in Cement Clinker Production

Abstract:

With the development of economy, China has become one of the largest cement producers in the world. However, cement industry is a main contributor of global carbon emissions. Substituting calcium carbide sludge for limestone is an effective method for CO₂emission reduction in cement industry and has developed rapidly in recent years in China. The purpose of this study is to determine the life cycle CO₂ emission of cement clinker produced with calcium carbide sludge as secondary raw material. The results show that compared with general cement clinker, the life cycle CO₂ emission intensity of cement clinker produced with calcium carbide sludge will be decreased by 39.1% when substitution rate is 80%. And the CO₂ emission results from the procedure of cement clinker production accounts for 85.7% of the total emission, in this stage, the CO₂ emission declined by 42.2%.
