  7. 5. Novel process integration opportunities in existing kraft pulp mills with low water consumtion

    Författare :Cecilia Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; excess heat; evaporation; pinch technology; pulp and paper; energy; system consequences; process integration;

    Sammanfattning : The economic opportunities for energy savings due to process integration of the evaporation plant have proven to be good in model mills with low water consumption. This is due to the fact that the temperature level of excess heat is higher compared with pulp mills with larger water consumption. LÄS MER
