Energy consequences in minimum effluent market kraft pulp mills
Paper i proceeding, 2002
The integration of kidneys involving evaporation without affecting the live steam demand in kraft pulp mills is discussed. The excess heat for evaporation is used to reduce the steam demand for the mill and reduce the cooling need. The making of excess heat available and use it, after process integration is completed, to reach energy savings is also discussed. The grand composite curves (GCC) were evaluated from the the process integration and identify the the potential for process modification through the curves.
