Efficiency decline in the recovery cycle of Kraft pulp and paper mills can create dynamic conditions that lead to evaporator scaling and poor combustion properties at the recovery boiler. In extreme cases, these dynamic conditions can evolve into production disruptions and mill shutdowns. Currently, operational strategies are often evaluated with steady-state models without the capability to simulate dynamics, leading to misinformed operational decisions. Dynamic modelling offers the opportunity to provide accurate real-time information to operators to pre-emptively manage dynamic conditions before shutdowns are required. To this end, this research project developed a dynamic model of a Canadian softwood/hardwood pulp mill using CADSIM Plus with model calibration from a mill-wide sampling campaign. Time and impact estimates of common dynamic conditions were determined to inform and improve existing operational strategies. Further, linking the model to mill measurements would equip operators with real-time chemistry measurement leading to optimized process control.
