Energy balance and cogeneration for a cement plant
The cement industry is an energy intensive industry consuming about 4 GJ per tonne of cement produced. A thermodynamic analysis for cogeneration using the waste heat streams is not easily available. Data from a working 1 Mt per annum plant in India is used to obtain an energy balance for the system and a Sankey diagram is drawn. It is found that about 35% of the input energy is being lost

The mass and energy balances for the cement plant concepts with carbon capture were used furthermore to evaluate the key plant performances. The designs were optimized by performing a heat integration analysis (using pinch technique) for maximization of the overall energy efficiency (Smith, 2005).As an illustrative example, Figure 1 presents the hot and cold composite curves for the calcium

ENVIRONMENTAL IMPACTS OF CEMENT PRODUCTION
Most of the balance is lost from the process as carbon dioxide emissions to air in the calcination reaction (CaCO3→ CaO + CO2) [1]. The amount of clinker needed to produce a given amount of cement can be reduced by the use of supplementary cementitious materials such as coal fly ash, slag, and natural pozzolans (e.g., rice husk ash and volcanic ashes). The addition of these materials into
