چکیده انگلیسی
Population balance models (PBM) have been used traditionally to model high shear wet granulation (HSWG) with wet binder addition where the binder is pre-dissolved in a liquid and added to the granulator. However, wet granulation with dry binder addition can not accurately be modeled with the models developed for wet binder addition since it involves the additional step of dissolution of the dry binder present in the granulator in the pure liquid added during liquid addition stage. In this work, a reduced order multi-compartment population balance model integrated with binder dissolution model was developed to address the differences in average diameter of particles obtained from dry and wet binder addition. Experimental data were generated on a 10-L PMA granulator using wet and dry binder addition modes. The experimental data were used to estimate the model tuning parameters to validate the model which was further used as predictive tool. This model showed good agreement with experimental data in capturing the trends in average particle diameter for two different binders, hydroxypropyl cellulose (HPC) and polyvinylpyrrolidone (PVP). The model was also able to accurately predict the average diameter for both the wet binder and dry binder addition cases.
