Energy balance and cogeneration for a cement plant ...

2002-4-1  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.

ENVIRONMENTAL IMPACTS OF CEMENT PRODUCTION

2014-5-27  To produce 1 tone of clinker, the typical average consumption of raw materials in the EU is 1.52 tones. Most of the balance is lost from the process as carbon dioxide emissions to air in the calcination reaction (CaCO3→ CaO + CO2). 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 concrete not only reduces the amount of material landfilled (in case of industrials byproducts), but also reduces the amount of clinker required per ton of cement produced. Therefore cement

MASS BALANCES - University of Washington

2009-1-5  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 must be there at all later times, albeit perhaps in different forms. In systems with transport across the boundaries of the CV and/or where the rate of change is important, mass balances are written in terms of rates rather than absolute amounts: the rate at which material accumulates in the CV equals the net rate at which it is carried into the CV by flow (i.e., advection), plus the net rate at which it is injected into or generated inside the CV by non-advective processes. Such processes might include addition of a dry chemical to the solution (we consider advection to include only liquid streams) or, more often, chemical reaction inside the system. Those who have taken the CEE 3xx curriculum have seen mass balances

Calculation methods to perform mass balances of ...

Two different methods are proposed to perform the mass balance calculations of micropollutants in sewage treatment plants (STPs). The first method uses the measured data in both liquid and sludge phase and the second one uses the solid-water distribution coefficient (Kd) to calculate the concentrations in the sludge from those measured in the liquid phase.
