2. Energy Efficient Evaporation in Future Kraft Pulp Mills
Abstract : In the future, the technical and economic conditions for energy savings in the pulp and paper industry will change. More excess heat will be available in future mills above 80°C than in existing mills, increasing the potential for process integration, and governmental actions for reducing CO2 emissions and the deregulation of electricity markets will change the economic conditions for investments aimed at saving energy.

3. Process Integration in Model Kraft Pulp Mills. Technical, Economic and Environmental Implications
Abstract : The technical and economic conditions for reducing the energy consumption cost-efficiently and thereby releasing a surplus of biomass fuel in the pulp and paper industry are changing. For example, new environmental restrictions increase the need for closed water loops and other system modifications, which can lead to increased opportunities for energy savings. READ MORE

4. Novel process integration opportunities in existing kraft pulp mills with low water consumtion
Abstract : 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. READ MORE

5. Energy Export Opportunities from Kraft Pulp and Paper Mills and Resulting Reductions in Global CO2 Emissions
Abstract : With increasing energy prices and increasing demand for CO2-lean energy sources, energy savings in the pulp and paper industry become ever more relevant. Significant energy savings in kraft mills can be made by e.g. improved heat integration and installation of an energy-efficient evaporation plant. READ MORE
