Повний текст джерелаThe simulation of bubble column reactors under industrial operating conditions is an exciting challenge. The main objective of this work is to predict the bubble size, in turn interconnected to the reactor hydrodynamic conditions, with computational models, by modelling bubble breakage and coalescence. Experimental data is collected for model validation, including bubble size measurements with an innovative cross-correlation technique. Experiments are carried out with tap water and demineralized water, with or without the addition of ethanol, and gathered results show that additives reduce coalescence and lower the mean bubble size. Two different spargers are used, in order to decouple the investigation of breakage and coalescence. The experimental data set is used to validate out unsteady three-dimensional Eulerian-Eulerian CFD simulations. A drag law for oblate bubbles is considered, together with a swarm factor, that accounts for the swarm effect. Several turbulence models are tested. The contribution of bubble induced turbulence (BIT) to scalar mixing is assessed. To predict bubble size, a population balance model is coupled to the hydrodynamic model and is solved with the quadrature method of moments. A set of breakage and coalescence kernels is proposed, capable of predicting the bubble size for different operating conditions. Scale-up effects are also investigated

Повний текст джерелаSimulations are becoming an essential tool to design and improve processes in the field of biotechnologies. They are especially relevant to facilitate the scale-up of biological cultures from laboratory to industrial scales which is a key difficulty as of now. This thesis focuses on developping a model structure for fermenters, which does not neglect either mixing issues known to occur in industrial bioreactor, nor biological complexity inherent to micro-organisms, while enabling fast and low-cost simulations. To account for all coupled and dynamic phenomena that occur in bioreactors, the developed approach couples (i) a dynamic metabolic model to describe cells behaviour, (ii) a population balance model tracking biological cell-to-cell diversity and (iii) a compartment model to account for fermenter hydrodynamics. A structure for low-cost dynamic metabolic model has been developed, applied to E. coli and S. cerevisiae and successfully challenged against experimental data. Among multiple numerical methods tackling population balance equations, the EQMOM method has been selected for its stability and precision, and its algorithm has been improved by reducing its cost by a factor 10. The gas-liquid hydrodynamics of an industrial fermenter has been obtained through CFD simulations, and tools have been developed to extract compartment model from these simulation results. Finally, the coupling between all these modeling blocks has been demonstrated by simulating an actual industrial culture. This work paves the way to the emergence of fast bioreactor simulation tools, which will then enable new enginnering studies for designing and optimising industrial bio-processes

Повний текст джерелаThis work aims to model the formation of whey protein aggregates during continuous thermo-mechanical treatment (heat exchanger) with integration of the physicochemical properties (protein content and mineral content). This simulation work is supported by knowledge from literature and experimentation carried out in addition with literature.A two-step work was done at two scales. At laboratory scale, the samples were submitted to well controlled and almost homogenous thermo-mechanical treatments. This was used as data base to develop a mechanistic model of transformation for the irreversible aggregation of beta-lactoglobulin in solution in function of time/temperature/shear. This first step allows obtaining a model for one profile but not for a pilot-scale heat treatment. The hypothesis is that the dispersion of aggregate sizes in continuous heat treatment is partly due to distribution of residence times: proteins in the slowest parts of the fluid have more time to aggregate. Experiments were carried out on a continuous pilot of heat treatment

Повний текст джерелаGetting constant quality products is a major issue for the pharmaceutical industry. This objective can be achieved by controlling the process and by understanding the physical mechanisms. Now, recent in-situ monitoring technologies have been developed. They make it possible to analyse the crystalliszation process in real time. In this script we have shown how in-situ Raman spectroscopy and on-line image recording have been used to study the crystalliszation and solvent mediated phase transition of citric acid. The different physical mechanisms involved during the process (nucleation growth and dissolution) have been investigated. A crystallization model solving a system of two populations balance equations has been programmed. It allows us to simulate isothermal seeded crystallizations and polymorphic phase transitions. A set of kinetic parameters has been estimated from the experimental data (solid phase composition, solute concentration and Crystal Zize Distribution). An optimization routine has been implemented to get significant numerical values

Повний текст джерелаIn this thesis we are concerned with the mathematical modeling of crystallization processes in order to understand, simulate, optimize and control them. We first present the principles of modeling, the fundamentals of crystallization and the numerical exploitation of models of crystallization. We then discuss exemplary a mathematical model of crystallization of KCl in continuous operational mode with dissolution of fines and product classiffication. This model is described by a hyperbolic partial differential equation coupled with an integro-differential equation. To justify the theoretical model, we prove existence and uniqueness of solutions using the method of characteristics and the Banach fixed-point theorem. We then present numerical simulations of the studied processes. In a third part of the thesis we develop and present a mathematical model of solvated crystallization of a-lactose monohydrate in semi-batch operational mode. We justify the model by proving global existence and uniqueness of solutions. Finally, we study the optimal control of crystallization of a-lactose monohydrate in semi-batch mode using the solvers ACADO and PSOPT. Optimal cooling and filling strategies are computed in order to enhance the properties of the solid

Повний текст джерелаThis thesis deals with the experimental study of gas-solid flows and the modeling of fluidized bed reactors. The industrial application investigated in this work corresponds to the carbochlorination of zirconium dioxide (ZrO2), which is an essential step for the production of zirconium metal. The main objective is to develop a model of the industrial reactors and provide a better understanding of their behavior. The approach consists first in studying the hydrodynamics of fluidized bed carbochlorination reactors. The results show that the carbon black acts as a flow conditioner (glidant) and improves the flow properties of the ZrO2/C mixture. The presence of tiny spherical carbon nanoparticles on the surface of relatively large oxide particles reduces the interparticle forces and friction between adjacent particles. A good dispersion of the carbon nanoparticles is needed to enhance their ability to act as a glidant and also increase the resistance to segregation of the resulting mixture. From the experimental data, different methods and correlations are developed to predict the agglomerate size and density, the minimum fluidization velocity, the bed expansion and the elutriation flow rate. Then, a carbochlorination reactor model is developed by coupling hydrodynamics and kinetics. This model allows the resolution of unsteady-state mass and energy balance equations as well as population balance equations. It is thus possible to predict the chlorine conversion, the composition of the product gas, the elutriation flow rate and the particle size distribution in the bed depending on the operating conditions
