Повний текст джерелаLignocellulosic biomass is considered as a renewable carbon resource with great potential for the energy and chemical recovery. Torrefaction is a thermal process carried out at temperatures below 300°C, under inert atmosphere, at atmospheric pressure, and with residence times for the solid biomass ranging from few minutes to several hours. Torrefied wood is a solid product constituted by more than 70% of the initial mass with properties close to those of coal. The 30% remaining part is a gaseous effluent, composed of about one third of non-condensable gases – carbon monoxide and carbon dioxide – and two thirds of condensable species. Currently, torrefied wood is the main product of interest and is usually transformed into energetic gases by the gasification process or directly used as coal for combustion. Conversely, gaseous by-products are considered at present time as a waste and in the best case are burned to provide energy to the process. Yet, the recovery and valorization of the condensable fraction as bio-sourced chemicals is worth considering. The aim of the thesis is to propose a separation-purification process for condensable chemicals of the waste gas. This condensable fraction is a predominantly aqueous phase, containing more than 150 identified organic species. Minority species are present in varying proportions depending on torrefied wood. Finally, it is a reactive and thermally unstable mixture, where different chemical equilibria are present. An analysis of the physicochemical characteristics of the condensable fraction allowed selecting a limited number of compounds to model the mixture. A representative model of the thermodynamic behavior of the reactive mixture has been selected and the binary interaction parameters identified. Experimental vapor-liquid equilibria data were acquired in part to validate this model. The target compounds and objectives of the recovery process were selected and several development strategies were developed and simulated in ProSim+ on the basis of thermodynamic modeling. This study assessed these different strategies in terms of energy efficiency and purity of the products for potential implementation on an industrial scale of this sector

Повний текст джерелаHydrothermal oxidation processes in supercritical fluid provide an innovating alternative for the management of energetic materials at the end of their "lifetime" and of the production's wastes. In order to evaluate and promote the development of this technology, two hydrothermal oxidation pilots were built. The first set up in batch mode; the reactor is protected by a lined titanium. It is dedicated to feasibility studies on real products such as propellants and the various elements of their composition. Concerning the second one, it operates in a continuous mode based on a new concept of reactor : a multi injection of oxygen along the hydrothermal oxidation reactor. This facility is devoted to the determination of data necessary to scale industrial reactors. Model molecules such as acetic acid, methanol and phenol were studied. A calculation method was developed to obtain reaction kinetics parameters, in particular the order compared to oxygen concentration. On the basis of theses kinetics data the software "Prosim Plus" was validated to simulate the hydrothermal oxidation process

Повний текст джерелаSubmicron 3D structures are required in many fields (photonics, optics, biology, etc.). Fabricating such structures is difficult. Multiphoton polymerization is a suitable technique, but current fabrication times are long (one day to fabricate a mm3 structure), making industrial production costly and limiting the development of these structures. We present our contribution to the development and optimization of a massively parallelised multiphoton polymerization fabrication process for these structures. Two parallelization techniques are investigated at IMT Atlantique: one using a diffractive optical element and another, studied in this thesis, using a spatial light modulator in an imaging configuration and an ultra-sensitive TTA resist (Triplet-Triplet Annihilation), enabling writing with 1920 × 1080 beams in parallel. The use of multiple write beams can lead to resolution limiting proximity effects. We present our numerical simulation model of the photochemical process to understand, predict and correct these effects. We present possible improvements based on these simulations and the improved understanding of the optical system. The fabrication method we have developed enables us to fabricate structures with a resolution of around one micrometer in X,Y and several tens of micrometers in height on surfaces of the order of cm2 in just a few minutes. Finally, examples of applications in biology and ophthalmology, adapted to the photoplotter performance are presented

Повний текст джерелаThe calcination-vitrification process has been used in France for over 30 years for the containment of high level nuclear waste arising from the spent fuel reprocessing. The use of numerical tools has proved to be essential for the process understanding and optimization. In the past ten years,numerical simulation works on the thermal, hydraulic and electromagnetic aspects involved in the vitrification process have been carried out in the context of the cold crucible development, a new type of furnace commissioned in 2010. As a continuation of these studies, the objective of the phd work is to add to the existing simulations, a modeling of the chemical aspects taking place during the nuclear glass synthesis, especially during the feeding with glass frit and calcine. In this perspective, a kinetic modeling of the reaction mechanism has been proposed based on data from thermal analyses. The coupling of this model with the magneto-thermo-hydraulic simulation tools was implemented and validated based on tests carried out at the mock-up scale and data from the industrial scale. Particular attention has been paid to identifying the nature of chemical reactions

Повний текст джерелаIn this work the modeling, simulation, dynamic optimization and control of a Plasma Assisted Reactive Evaporation process (PARE) for the deposition of Zinc Oxide (ZnO) thin films are proposed. Initially, a dimensional unsteady-state model was developed for the process, this model apply dynamic material balances to the process and accounting for diffusive and convective mass transfer, and bulk and surface reactions in order to establish the space-time evolution of the concentration of the species (O_2(g) , O_((g))^., O_((g))^-, 〖Zn〗_((g)), 〖Zn〗_((g))^+ and 〖ZnO〗_((g))) present throughout the reactor and compute the final film thickness. The case of study corresponds to a pilot reactor operated by the Semiconductor Materials and Solar Energy Research Group (SM&SE) of the Universidad Nacional de Colombia where the ZnO thin films are used for the fabrication of different kind of solar cells (inverted inorganic solar cells, organic solar cells and perovskite based solar cells). The equations are spatially discretized using finite difference methods and then implemented and solved in time using Matlab®. The simulation results are validated by means of COMSOL MULTIPHYSICS® which computes the same results; However, to complete the others objectives of the project it will keep using the finite difference method under Matlab® because it offers more flexibility in the perspective of dynamic optimization and control of PARE process. To corroborate the model, experimental measurements of ZnO film thickness were carried out using a thickness monitor on a pilot reactor designed and implemented by the Semiconductor Materials and Solar-Energy (SM&SE) Research Group at Universidad Nacional de Colombia. After 90 min of deposition time the simulated results and the experimental measurements exhibit a very good agreement, just around 20 nm discrepancy in the final thin film thickness hence showing the high accuracy of the developed model. The dynamic optimization problem is transformed into a non-linear programming (NLP) problem using the CVP method, i.e. the control variables are approximated by means of piecewise constant functions. It is then implemented within Matlab and solved using fmincon optimizer. Two different optimization problems are proposed., in the first problem Zn flow rate (V_(w,Zn)) is considered as control or manipulated variables u(t) and in the second problem both Zn flow rate (V_(w,Zn)) and Oxygen flow rate 〖(V〗_(w,O_2 )) are considered as manipulated variables. Quality constraints are established according to experimental studies that were performed in order to determinate the final product properties such as Transmittance, Resistivity, Film thickness and reactor parameters. Two optimization problems are solved taking as control variable the Zn flow rate and Oxygen flow rate in order to minimize batch time while some thin film desired properties (transmittance, resistivity and thickness) satisfy the defined constraints. The batch time was reduced in a 15% with respect to the current operating conditions used by the Semiconductor Materials and Solar Energy research Group. Finally, the optimal profiles of the Zn flow rate and Oxygen flow rate that were obtained in the optimization part were used to develop and simulated a regulatory control algorithm using the Simulink toolbox of Matlab®. The results obtained in the simulation of the control algorithm show that the designed controller has an appropriate performance by following the optimal flow trajectories and the ideal ratio of Oxygen and Zinc
