The kraft chemical recovery process is a mature, effective technology that provides for recycling of the pulping chemicals, efficient generation of steam and electrical
power from the fuel value of the black liquor, and effective disposal of dissolved wood substances. The process now faces significant challenges with respect to air emissions, effluent discharge, and the need for improved energy recovery and utilization. New technology may result in significant energy benefits, and precise planning is essential for new or modified power plants.
A reliable heat balance and performance model is a key factor for any successful pulp and paper project: At early project stages it is necessary to determine whether and how the requirements can be achieved. At later stages in serves for identification of operational limits and to determine optimum operating points.
Previously, separate process modeling packages were typically used for the steam and power cycles and the kraft recovery sections of pulp and paper plants, but with its open and flexible framework, and its robust and comprehensive model libraries, IPSEpro can be used to model a complete, integrated pulp and paper plant. IPSEpro is the ideal platform for creating heat balance and performance models for pulp and paper plants, integrating both the kraft recovery and the steam and power cycles.
