Download or read book Dynamic Modeling of Unsaturated Polyester Production from Maleic Anhydride and Propylene Glycol written by and published by . This book was released on 2010 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: To predict the effect of reaction temperature and the inert gas feed rate on condensation polymerization of unsaturated polyester between maleic anhydride and propylene glycol. The developed dynamic model consisted of three parts, the reactor model, the kinetic model and the mass transfer model. The simulated result was verified by comparing to the process identification from the experimental data. The comparison of the simulation and experiment gave a satisfaction and the developed model was valid. The simulation illustrated that the effect of reaction temperature and the inert gas flow were more complicate to the process parameters because of the changing in the bulk liquid properties during polymerization. Both of reaction temperature and the inert gas flow rate were influence to the process parameters via the exact and diverting paths. Increasing of reaction temperature would increase the rate of condensation polymerization by enhancement of rate constant. Increasing of inert gas flow rate would increase the polymerization rate by increasing of specific interfacial area for mass transfer. In both two cases, the reaction time should decrease.

Available in PDF, EPUB and Kindle. Book excerpt: Polyethylene is one of the most widely used plastics, and over 60 million tons are produced worldwide every year. Polyethylene is obtained by the catalytic polymerization of ethylene in gas and liquid phase reactors. The gas phase processes are more advantageous, and use fluidized-bed reactors for production of polyethylene. Since they operate so close to the melting point of the polymer, agglomeration is an operational concern in all slurry and gas polymerization processes. Electrostatics and hot spot formation are the main factors that contribute to agglomeration in gas-phase processes. Electrostatic charges in gas phase polymerization fluidized bed reactors are known to influence the bed hydrodynamics, particle elutriation, bubble size, bubble shape etc. Accumulation of electrostatic charges in the fluidized-bed can lead to operational issues. In this work a first-principles electrostatic model is developed and coupled with a multi-fluid computational fluid dynamic (CFD) model to understand the effect of electrostatics on the dynamics of a fluidized-bed. The multi-fluid CFD model for gas-particle flow is based on the kinetic theory of granular flows closures. The electrostatic model is developed based on a fixed, size-dependent charge for each type of particle (catalyst, polymer, polymer fines) phase. The combined CFD model is first verified using simple test cases, validated with experiments and applied to a pilot-scale polymerization fluidized-bed reactor. The CFD model reproduced qualitative trends in particle segregation and entrainment due to electrostatic charges observed in experiments. For the scale up of fluidized bed reactor, filtered models are developed and implemented on pilot scale reactor.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this thesis is the investigation of modeling and optimization particularities of tubular polymerization reactors. The original work is divided in two sections, the first treating a modeling and optimization study of tubular reactors for methyl methacrylate polymerization in solution, and the second, an experimental and theoretical study of L-lactide reactive extrusion. In the first section, reactor simulations in similar operating conditions were performed in order to select a representative kinetic model among the published kinetic models for MMA solution polymerization. Two widely used numerical algorithms, one based on Pontryagin's Minimum Principle and the other a Genetic Algorithm, were compared for an average-complexity optimization problem. The results showed a superior robustness of the Genetic Algorithm for this category of problems. The second part of the thesis deals with the modeling and optimization of L-lactide reactive extrusion. A kinetic model is proposed and its parameters estimated using nonlinear estimation numerical procedures based on experimentally measured data. Reactive extrusion experiments were performed in representative operating conditions. The Llactide/ polylactide flow in the extruder was characterized by simulation using the commercial software LUDOVIC®. The simulated residence time distributions characteristics are used to model the reactive extrusion process of two approaches, an axial dispersion model and a compartment model, based on compartments whose characteristics are deduced from the simulations using LUDOVIC®. The modeling results are in good agreement with the measured data in the same operating conditions.
