### Use of an Energy Balance around the Mill Sump to Estimate ...

energy balance around the mill discharge sump will be described. If a measurement of the density and volu metric flowrate of the slurry flowing from the sump is available, then the flowrate of solids in this stream can be calculated. At steady-state this will be equal to the solids flowrate from the mill. It remains

### Energy Balance of Kraft Pulp (KP) Mill

In case of kraft pulp and stone mills energy sources are 15.8% of purchased energy and 84.2% of black liquor. Analyzing energy balance, we could operate the KP mill using black liquor only, if we save the energy by 6.6%. Case studies of save the energy which we are trying now, shows as follows ; (1) Making higher black liquor consistency.
