文摘内容 Static and dynamic models were studied for bothsoftwood and hardwood viscosity loss during Kraftpulping process. G-factor and initial EA charge in thestyle of Hatton equation can predicate final pulpviscosity. Dynamic models generated by effectivealkaline (EA) and temperature profile informationcan be used to predicate pulp viscosity at any timeduring pulping process. Viscosity online real-timeprediction is made possible by this model through anonline NIR sensor, which has been well calibrated tomeasure black liquor EA and temperature。
