Computational Fluid Dynamics and Population Balance Modeling of Particulate Systems
… The models focus on the combination of population balance equations and computational fluid dynamics software. For the simulation of antisolvent crystallization, knowledge of kinetics at high supersaturation are necessary. Chapter 2 describes the concentration profile within a …

Multidimensional population balance modeling and optimization of continuous reactive crystallization
… rate. This thesis presents a multidimensional population balance model (PBM) framework that models CSD with two independent characteristic lengths or 2D PBM. Compare with the 1D PBM, the extra characteristic length in the 2D PBM provides enough degrees of freedom to model needle-, plate-, and …

Multiscale Modeling and Mechanistic Analysis of Crystallization and Particulate Processes
… molecular dynamics simulations, microkinetic modeling, and population balance modeling are used to investigate crystallization phenomena across molecular, mesoscale, and continuum scales. We observed that antisolvent crystallization and oiling-out are governed by disruption of hydration shells …

Vibrations for improving multiphase contact
… size distribution were also investigated and population balance modeling was performed to explain the experimental observations. Performance of a novel three phase POMR was studied for two reactions: hydrogenation of alpha-methyl styrene to cumene and partial hydrogenation of soybean oil using …

Crystallization process development and spherical agglomerates for pharmaceutical processing applications
… with both high yield (>90%) and purity (>99%). Population balance modeling was performed and experimental data were fit to the model to obtain kinetic parameters for crystal growth and nucleation for both systems. The models were used to optimize crystal purity and yield of the products. In …

A Comprehensive Dynamic Model of the Column Flotation Unit Operation
… obtained from fundamental material and/or energy balances, or from phenomenological derivations based on knowledge about the behavior of the system. A phenomenological approach referred to as population balance modeling was employed here. Initially, a two-phase model was formulated, which …

Stochastic modeling of nonisothermal antisolvent crystallization processes
… to choice a stochastic approach instead of a population balance modeling has been developed to find a simple and an alternative way to describe the evolution of the Crystal Size Distribution (CSD), without consider complex thermodynamic and kinetic aspects of the process. An important …
