G-factor and initial EA charge in the style of Hatton equation can predicate final pulp viscosity. Dynamic models generated by effective alkaline (EA) and temperature profile information can be used to predicate pulp viscosity at any time during pulping process. Viscosity online real-time prediction is made possible by this model through an online NIR sensor, which has been well calibrated to measure black liquor EA and temperature.展开更多
