In an average cement plant, the production of one ton of cement results in the emission of approximately 0.5–0.9 tons of CO 2 (Rubenstein 2012). The exact amount of emission varies depending on the production process, heat recovery methods, clinker–cement ratio, raw materials and fuels (Plaza et al. 2020). The cement industry …

But IPCC tier 3 is impractical in many cement plants. In general, the test carbonate content of raw material is a complex process. However, in many cement plants the homogenized mass flow of raw meal is routinely monitored including its chemical analysis for the purpose of process and product quality control.
Combustion and the Cement Process. Pyro-processing is the heart of the cement-making process. It is usually the major cost element and kiln performance dictates the efficiency, plant output, emissions, product quality, and plant run factors.
This application note explains how ABB's gas analyzers can measure false air in cement production, reducing energy consumption and emissions.
Thus, the first material flow route for cement plants was examined in this study. Additionally, a cement plant was surveyed to quantify the amount of material consumed during the cement processing stages by using the mass calculation method discussed in section 3. In the surveyed cement plant, three balances are established …
