Der volle Inhalt der QuelleOptical fibers with tailored spectral response are doped with luminescent ions, rare-earth ions (re), embedded in nanoparticles (np) formed in situ in silica glass through a phase separation process. This engineering requires to understand the relation between the np composition and the re environment. In molecular dynamics, the existing interatomic potentials fail to reproduce the phase separation as experimentally observed. The system xmgo-(1-x)sio2 exhibits a domain inside of which two mixed phases coexist, mg-rich either si-rich. Such a phase separation can only be modeled by an interatomic potential that takes into account bond ionicity, and the transferability isEnabled here by the adaptation of oxygen charges according to the local environment. This adaptive model allows for the 1st time to track the formation of amorphous np of few nanometers. Mixed and mg-rich, they separate from a si-rich matrix. The re doping (er3+ or eu3+) shows that re environment depends on the size of the containing np: the bigger it is, the more the proportions of embedded re and mg increase. Thus, this mg-rich environment enables re ions to increase their oxygen coordination and to no more aggregate to each other to satisfy this natural trend. A simulation of the high-temperature drawing of silica-glass confirms the existence of an anisotropy in optical fiber, explained by the persistent orientation that small silica rings acquire in this fiber, and manifests itself by an elastic anisotropy. The nontrivial effects induced on np by these extreme conditions of temperature and stress can be studied later. The crystal-field model can be used to correlate the changes of the re environment with their spectral response
Elgendi, Ayman Taha. „Préparation et étude de Membranes Asymétriques Polyalcoxyétherimides (PEI) pour la séparation de composés organiques de l'eau“. Thesis, Vandoeuvre-les-Nancy, INPL, 2010. http://www.theses.fr/2010INPL046N/document.
Der volle Inhalt der QuelleThe work aimed to prepare co-polyalkylether-imide (PEI) asymmetric membranes in order to get high flux water selective polymeric membranes suitable for the separation of organic molecules from aqueous mixtures by membrane processes. The separation of liquid mixtures (i.e. toluene – heptane, water – ethanol and low concentrated organic solute in aqueous solutions) was studied by pervaporation (PV) and by nanofiltration (NF) using homemade integrally skinned asymmetric PEI membranes. These membranes were prepared under controlled experimental conditions from DMF-H2O solutions of the corresponding polyamic acid (PAA) with respect to the ternary phase diagram; after the wet phase inversion in a water bath, the PAA membranes were imidized by thermal treatment. The membrane physical properties (IR, TGA) were characterized and the related morphologies, recorded by SEM, were used to optimize the asymmetric membrane preparation to improve the separation properties by tuning the thickness of the dense top layer. The performances of the pervaporation and nanofiltration separations were examined in the light of the influence of three sets of parameters, i.e. membrane elaboration parameters (dope composition, inversion bath temperature), experimental permeation conditions (temperature, applied pressure) and solute molecular properties (molecular weight, radius, polarity). The PV results showed that tight asymmetric PEI membranes could well be obtained, giving rise to a molecular selectivity in agreement with the solution-diffusion model. The NF results obtained with diluted organics in water (≈500ppm) have shown that the degree of rejection of the organic solutes was strongly linked to the PEI elaboration conditions and to the solute properties. The molecular cutoff values (MWCO) of the membranes were determined with a series of polyethyleneglycol (400 < Mw (g/mole) <6000) for an applied NF pressure up to 10 Bar; it was shown that the PEI membrane MWCO could be ranged between 400 and 1000g/mol at 30°C. It was also found with some PEI membranes that high permeation fluxes together with good separation selectivity could be obtained leading to interesting performances compared to literature data. Thus, it is expected that the development of these new asymmetric block copolyimide rubbery membranes might give rise to high performance membrane systems for applications in liquid-liquid separations, in particular in nanofiltration separations

Der volle Inhalt der QuelleCurrently, the emission of CO₂, which is the primary contributor to global warming, is increasing at an alarming rate. Consequently, there is a growing global need for cutting-edge technologies that can effectively separate and capture CO₂. In the present work, a series of PSF/IL and PES/IL composite membranes for CO₂ separation were investigated. Six ILs ([Meim][TFSO₃], [Vim][TFSO₃], [Meim][Tf₂N], [Vim][Tf₂N], Li(DOBA)[Tf₂N] and Li(HDA)[Tf₂N]) were synthesized successfully and characterized by FT-IR, 1H NMR, TGA and DSC. Composite membranes with different IL loadings were fabricated by solution casting method and exhaustively studied by FT-IR, TGA, DSC, SEM, F-mapping, surface energy, tensile tests, and gas permeation (CO₂, N₂ and O₂). Under 25°C and 4 bar, PES/10[Vim][Tf₂N] membrane showed a CO₂ permeability of 1.92 Barrer with improved CO₂/N₂ and CO₂/O₂ selectivities of 20.4 and 6.1, respectively

Der volle Inhalt der QuelleComposite membrane structures are inevitable for the next step of mixed matrix membrane development as the commonly used asymmetric membrane design would mean majority of the fillers to be wasted in the bulk porous substrate layer. In this research, the possibility of using poly(4-methyl-1-pentene) (PMP) as substrate – gutter layer in composite membrane was compared with commonly used polydimethylsiloxane (PDMS) as gutter layer, supported on lithium chloride (LiCl) modified polyethersulfone (PES) porous substrate of varying surface pore architectures. Composite PES/PDMS was able to obtain permeance as high as 26.6 ± 2.6 GPU for N2 and 354.4 ± 27.9 GPU for CO2 at about 1 µm minimum coating thickness. Nevertheless, this value is lower than asymmetric dense skin PMP membrane at 84.6 ± 6.2 GPU for N2 and 607.3 ± 31.3 GPU for CO2. Despite that PDMS has intrinsic permeability far higher than PMP, PES/PDMS composite suffers from solution intrusion & geometric restriction problem at its dense – substrate interface, which reduces its permeance efficiency as low as only 4% of its supposedly ideal permeance, at low coating thickness. It is further elucidated that substrate surface uniformity also significantly affects the resulting composite permeance. In comparison, asymmetric PMP with thin dense surface layer was noted to be advantageous as the substrate – gutter layer as it mitigates the interfacial problem noted earlier for composite membranes while still being highly permeable to minimize resistance. Hence, N2/CO2/CH4 gases were chosen as the model permeants for further composite fabrication with P84 polyimide (PI) as selective layer. Nevertheless, low surface energy of PMP limit its compatibility to form a composite layer. However, it was noted that PMP is compatible to form a bilayer through dip coating with P84 PI, without the need for pre-treatment. Hence, P84 PI of various concentration was dip coated at 5 mm/s onto PMP-based dense skin hollow fiber membrane and tested for gas permeation performance. Results showed that ideal selectivity as high as 42.36 ± 19.08 for CO2/CH4 and 18.55 ± 6.06 for CO2/N2 was achieved at 14 wt.% P84 PI coating. Nevertheless, despite of PMP’s resistibility to the harsh N-methyl-2-pyrrolidone (NMP) solvent used for P84 PI solvation, introduction of P84 PI at low concentration (2 – 10 wt.%) damages the thin, dense skin layer of the PMP’s membrane surface which jeopardize the composite’s separation performance. It is hypothesised that P84 PI’s shrinkage during drying teared the underlying PMP layer which caused this degradation. Hence, there exist a minimum P84 PI polymer concentration in which a defect free selective layer can be made (which is at about 14 wt.%). At this concentration, dip coating speed can be manipulated to obtain a thinner defect-free selective layer suitable for composite membrane fabrication, although dewetting of the coating solution still occurred and magnified as the coating thickness is reduced

Der volle Inhalt der QuelleThis work is conducted in the framework of cuttlefish Sepia officinalis by-products up-grading from conditioning industries. It concerns the implementation of the enzymatic hydrolysis and the membrane separation processes to obtain valuable compounds such as peptides and lipids. The techniques used in this study belong to « clean technologies », environmentally sound involving moderate investment and low energy consumption. Hydrolysis of cuttlefish viscera had been carried out in two steps. The first one had objective to determine the efficiency of the enzymes on the matrixes investigated as well as the study area. Once the enzyme had been chosen, the second step was to optimize enzymatic hydrolysis using experimental designs, in order to obtain the highest small peptides recoveries the soluble phase and an antimicrobial activity. The fractionation on the protein hydrolysate according to the charge upon ion exchanging columms allowed determining the ionic profile of the antimicrobial peptides. Membrane fractionation (ultrafiltration) was then used as a second lever to act (i) on size distribution of peptides and (ii) on the activity level of the hydrolysates. First, small-scale fractionation was carried out on polyethersulfone and regenerated cellulose membranes with molecular weight cut-offs ranging from 1000 to 100 000 Da. Then, an scaling-up methodology was investigated by ultrafiltration of the hydrolysate on a pre-industrial pilot plant. The originality of this PhD work is (i) the enrichement of cuttlefish viscera hydrolysates with valuable compounds such as essential amino acids and the enhancement of the antimicrobial activity and (ii) the possibility to up-scale enzymatic hydrolysis and ultrafiltration integrating them in the conception of a complete industrial process

Der volle Inhalt der QuelleTHE MAIN GOAL OF THIS WORK WAS TO UP-GRADE SARDINE (SARDINA PILCHARDUS) BY-PRODUCTS USING MILD PROCEDURE, ENVIRONMENTALLY SOUND, IN ORDER TO OBTAIN VALUABLE COMPOUNDS INVOLVING MODERATE INVESTMENT AND LOW ENERGY CONSUMPTION. HYDROLYSIS AND ULTRAFILTRATION TECHNIQUES HAVE BEEN INVESTIGATED. FIRSTLY, SELECTED ENZYMES HAVE BEEN CALIBRATED IN ORDER TO DETERMINE THEIR OPTIMAL CONDITIONS WITH A MODEL SUBSTRATE AND TO PERMIT THE COMPARISON BETWEEN THEM. THEN, HYDROLYSIS ON SARDINE HEAD AND VISCERA HAVE BEEN CARRIED OUT IN TWO STEPS. THE FIRST ONE HAD THE OBJECTIVE TO DETERMINE THE ENZYME EFFICIENCY AND THE STUDY AREA. THE SECOND STEP WAS TO OPTIMISE ENZYMATIC HYDROLYSIS USING EXPERIMENTAL DESIGNS. THE AIM OF THIS SECOND STEP WAS TO OBTAIN THE HIGHEST LIPID RECOVERY IN THE LIQUID FRACTIONS USING THE VARIATION OF THE INFLUENTS HYDROLYSIS PARAMETERS SUCH AS TEMPERATURE, HYDROLYSIS TIME AND ENZYME CONCENTRATION. THE SOLUBLE PHASE OBTAINED AFTER THIS OPTIMISED STEP HAVE BEEN FILTERED USING ULTRAFILTRATION TECHNIQUE IN ORDER TO SEPARATE LIPIDS FROM PEPTIDES. LIPIDS FROM SARDINE BY-PRODUCTS HAVE BEEN MAINLY RECOVERED IN THE LIQUID FRACTIONS OF THE HYDROLYSATES. MOREOVER, AQUEOUS FRACTION HAS SHOWN A HIGH CONTENT OF PHOSPHOLIPIDS. W3 FATTY ACIDS REPRESENT AROUND 20% OF THE TOTAL FATTY ACIDS INTO THOSE FRACTIONS. REGARDING VISCERA, WHICH IS A HARDLY CRUSHING MATRIX, THE LIPID EXTRACTION YIELDS HAVE BEEN IMPROVED USING ENZYMATIC TREATMENT COMPARED TO TRADITIONAL EXTRACTION. THE ULTRAFILTRATION TREATMENT OF THE SOLUBLE PHASE HAS ALLOWED, AFTER THE DETERMINATION OF OPERATING CONDITIONS, TO SEPARATE LIPIDS FROM PEPTIDES AND TO CONCENTRATE THE PHOSPHOLIPIDS IN THE RETENTATE

Der volle Inhalt der QuelleThis work is placed in the study of molecular dynamics at glass transition for polar polymers. Firstly, we have studied the characterization of few polymer serials. Secondly, we are interested to the study of molecular relaxation in the glassy state and in the glass-forming liquid state. So, we have studied three serials of materials: EVA with different content of VA, EVA hydrolyzed with different reaction time, blends of PVC/EVA. We have determined the glass transition, cristallinity and thermal degradation for each material. These results allow knowing the structure of polymers. In collaboration with chemistry laboratory UMR 6522, we correlated the material structure with the permeation properties. Indeed, these polymers used in packaging for food and good selectivities of these membranes are very interesting. Moreover, three materials (EVA containing 70% in weight of VA, PVC and a blend of these two polymers have been studied for determine the molecular dynamic at glass transition. The glass state has been characterized by Tool-Narayanaswami-Moynihan model, thus permit to understand the structural relaxation in glass. For the glass-forming liquid, we have used the Vogel-Tamman-Fulcher model and Arkhipov model. This last tries to explain all the relaxation phenomena in the glass-forming liquid. In one hand, we demonstrated that this model allow to determine the distribution of cooperative rearranging regions at glass transition in material and the a relaxation cooperativity. In regard to the fragility concept, the energy landscape is good predicted by the Random Walk Model. In another hand, we have demonstrated that the molecular dynamic is strongly correlated at the polarity of materials

Der volle Inhalt der QuelleLimiting carbon dioxide (CO2) emissions is a major global issue, particularly for the energy, chemical and metallurgical industries. To this end, CO2 capture technologies have been developed in recent decades. In this study, we focused on three types of CO2 capture technologies: chemical absorption by MEA, membrane separation and activated carbon adsorption. The CO2 considered is emitted by a coal-fired power station and then directly valorized within a manufacturing process on the same site. The objective of this study was to quantify the environmental benefits of installing a CO2 capture technology in comparison to the current configuration, without CO2 capture. Our approach combined process modeling and life cycle assessment. The methodology adopted was to model the complete system (the power plant, the manufacturing process and the various capture units) using a flowsheeting software (Aspen Plus), then to determine the environmental impacts by LCA. The results show that the MEA chemical adsorption process is strongly penalized by the use of the solvent, both regarding the energy consumption and the environmental impacts. The membrane process exhibits significant environmental impacts, despite a much lower energy consumption, due to the massive use of polymers (membrane materials). Finally, the activated carbon adsorption process has lower environmental impacts than the other two processes in the vast majority of impact categories

Der volle Inhalt der QuelleIn a sustainable context, methodologies for multi-criteria optimization of green processes for the recovery of antioxidant polyphenols from by-products have been proposed, taking into account the total polyphenols yield, the antioxidant activity of the extracts obtained from chicory ground and the energy consumption of the equipment during processing time. Study on ultrasound-assisted extraction has helped to highlight the gains in processing time and energy through the application of ultrasounds. A comprehensive model was developed as a tool for multi-criteria optimization (total polyphenols yield, antioxidant activity and energy consumption) of extraction conditions (including time, temperature, solvent composition and power of ultrasounds). After preliminary studies on extract's enrichment using different adsorbents, the Amberlite XAD 16 resin was chosen as the most suitable for the adsorption of polyphenols extracted from chicory ground. An integrated process for simultaneous extraction and purification allowed enrichment in polyphenols of 2 to 4 times of chicory ground extracts. A model for multi-criteria optimization of this process has been proposed taking into account the amount of recovered polyphenols, the antioxidant activity of the extracts and the energy consumption of the equipment in function of operating conditions: processing time, aqueous phase flow and chicory ground-adsorbent ratio

Der volle Inhalt der QuelleThe depletion of resources and the accumulation of pollutant gases in the atmosphere are nowadays of growing concern. The current energy transition requires that certain material and energy transformation processes be partially modified or profoundly reconsidered to fit more sustainable operating conditions. Low-carbon electricity and hydrogen can substitute fossil fuels, leading to an energy mix with a low greenhouse gas (GHG) footprint. In addition to hydrogen, the production of alternative fuels and high value-added products is another way to support the energy transition.Looking for optimal, sustainable and economical processes is therefore a major challenge that process engineers are facing. The present work has thus focused on the intensification of mass and energy transformation processes, through multifunctional units, which take advantage of the synergies between elementary functions of transformation (reaction, transfer, separation, etc.) within an intensive equipment. The concept of multifunctional reactors, coupling several elementary functions, has been a real success when historical demonstrators were created (Eastman-Kodak process, etc.), but their implementation has not been generalized, due to a lack of practical design methodology.This work focuses on the implementation of some intensification methodologies to understand and improve the performance of a process involving balanced exothermic reactions. The dimethyl ether (DME) direct synthesis from CO₂ and H₂ is considered as a case study. Different exploratory ways for the DME direct synthesis process development have been investigated based on modeling and simulation. Reactor- Heat exchanger, multifunctional reactor (reactor-heat exchanger-membrane separator), hybrid elementary block processes and a process involving the cooled reactor in a conventional process environment in the presence of additional unit operations and recycle loop are studied from different angles. Different optimization cases and strategies have been addressed which differ by the decision variables and the solving method. The different methodologies applied have demonstrated the relevance of the solutions obtained and the opening towards process innovation.At the equipment level, the profiles optimization represents the heart of the methodology. The results demonstrate the potential of multifunctional reactors: a CO₂ conversion per pass of 98%, a DME yield of 95% and the possibility to remove a distillation column are obtained. In order to assess the maximum achievable performance in a multifunctional reactor, a hybrid process of elementary blocks has been optimized. At the process scale, the reactor behavior has been studied to further understand the impact of the reactor integration in a recycle loop and to estimate the local and global effects on the multiple performance criteria. Based on various criteria (overall DME yield, overall CO₂ conversion, TRL, etc.), the comparison of the different designs revealed that a reduction of the equipment number by a factor of 11 is possible in the case of a multi-functional reactor choice

Der volle Inhalt der QuelleStimulated biodegradation is a depollution technique used to degrade hydrocarbons. Its monitoring is currently done thanks to very few expensive wells. This PhD research work proposes to improve bioremediation monitoring by combining geophysical electrical methods (induced polarization) and CO2 analyses (surface emissions and carbon isotopic ratio). These tools were tested at laboratory scale and then implemented on a pilot site under decontamination. Aerobic degradation of toluene in columns by a known bacterial strain (Rhodococcus wratislaviensis) was characterized by CO2 production, carbon isotopic fractionation and by an evolution of electrical complex resistivity of porous media, in correlation with microbiological and geochemical analyses. These results allowed to implement a monitoring at the site scale. The site is a gas station where gasoline and diesel leaked fifteen years ago. A trench supply oxygen to the water table in order to stimulate aerobic bacterial processes. Geophysical campaigns and CO2 analyses have been carried out since February 2014. The first results show a more conductive and chargeable area which corresponds to the contaminated zone defined by geochemical analyses in wells. Moreover in this area CO2 emissions have been measured with an isotopic signature typical of hydrocarbon biodegradation. These results show the interest of combining geophysical methods with gas analyses to monitor biodegradation and they have already allowed to provide a non-destructive and new methodology for in situ monitoring

Der volle Inhalt der QuelleTechnologies using high temperature oxygen transport through mixed conductor materials undergo thermal andchemical expansions. The industrial structures suffer from thermo-chemo-mechanical stresses which may be modeled to predict their mechanical reliability. This work is a step toward the development of design tools for mechanics of structure made of mixed conductor. The goal is to deal with measurable parameters such as temperature and oxygen partial pressure. The first aim is to provide a realistic macroscopic modelling of chemical expansion. The second one is to model the coupling between mechanics, oxygen transport and heat transfer. The oxygen bulk diffusion is described following the Wagner theory. The kinetics of surface exchange and their consequences in terms of chemo-mechanical shocks have been explored. In order to conduct computation of complex structures in three dimensions with steady and transient state, the models have been implemented in finite element analysis software (Abaqus). Comparison with analytical results is also reported. Finally, a semi-industrial catalytic membrane reactor for partial oxidation of methane to syngas is computed. The modelling helps to analysed the impact of operating conditions on the mechanical reliability of the whole structure
