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.

MASS BALANCES

2 Mass balances take several forms. In some systems, no material enters or leaves the CV, and the rate of change is not considered important. In such systems, the mass balance simply states that everything that was present in the system at some initial time

Heat and Mass Balance

Heat and mass balance is a document produced by process design engineers while designing a process plant. Sometimes heat and mass balance is not a separate document but appears alongside the Process Flow Diagram (PFD). A heat and mass balance sheet represents every process stream on the corresponding PFD in terms of the process conditions.
