Full textAmong all kinds of atmospheric pollution, VOCs have raised a lot of interest recently. For high flow rates of low polluted gaseous effluents, one of the most suitable technologies seems to be biological treatment. However, industrial applications are limited because of impracticalities including short useful life or large plant size. In this situation, the use of the aero-ejector, a gas/liquid contactor with high transfer efficiency, is one solution for decreasing plant dimensions, if pressure drop is reduced. This research work deals with an evaluation of aero-ejector characteristics and performances and analyses the feasibility of a process associating the aero-ejector with a biological reactor for gaseous effluent treatment. Three model molecules were used ; the ethanol, the methyl ethyl ketone and the butyl acetate. The first section presents VOC treatment context, including existing technologies and their limitations. Descriptions of their application fields and costs allow comparison of these technologies. An analysis and optimisation of the aero-ejector performance as a mass transfer system is undertaken in the second section. Modifications of the internal geometry allowed the definition of a configuration suitable for industrial conditions concerning pressure drop and efficiency. A systematic study of the influence of operating conditions on transfer performances leads to the comprehension of the aero-ejector role in the contactor and to the definition of sizing criteria as a function of pollutants and technological constraints. Finally, in the third section, the system combining the aero-ejector with a biological reactor is studied for the complete treatment of a gaseous effluent polluted with several VOCs

Full textThis work of thesis approaches the problems of the development of packings intended for reactive distillation. Methodology to be followed is so applied in the case of ceramic foam in Silicon Carbide. The hydrodynamic behaviour was studied as well as the mass transfer efficiency demonstrating the possible application of ceramic foam as a packing for distillation. The aspect of the catalytic activation of the support was then developed in order to determine the most efficiency method in terms of catalytic activity making it possible to approach reference packing, the KATAPAK. The coating of Amberlyst 15 then appeared as the most interesting way for the possible application of coating foam as catalytic packing for reactive distillation

Full textThe purpose of this study is to propose to the industry and the technologies of the environment a device easy to build and upkeep which could be used for liquid and gas treatment, it is about a gas-liquid and gas treatment, it is gas-liquid contactor with immersed vertical jet. The first studies carried out (technique, hydrodynamics, mass transfer) provided a total point of view on the performances of this contactor. By approaching in a way applied enough the various aspects of the study, we could put in evidence the key points of this contactor. On the one hand, the high level of turbulences, created by impact of the jet, ensures a very homogeneous emulsion and mass transfer, on the other hand, the phenomenon of gas aspiration limits considerably the energy consumption. The works were then directly to the application of this apparatus in treatment of waste water. The obtained results showed that our device is well adapted to this type of treatment

Full textThe present work aims to explore the intensification of gas-liquid absorption processes. This study is applied to post combustion CO₂ capture by means of membrane contactors in comparison to packed columns. Microporous hollow fiber membrane contactors lead to high mass transfer but wetting problems are likely to occur and result in tremendous deterioration in performances with time. Our objective is to develop composite hollow fibers based on a microporous structure and a thin dense layer highly permeable to CO₂, in order to create a real barrier to liquid penetration and to limit mass transfer resistance. Super glassy polymers as PTMSP and Teflon AF2400 were selected for their extremely high CO₂ permeability and their chemical resistance to MEA (reference absorption liquid). Composite hollow fibers were made by coating and the dense layers obtained are thin (1 to 2 microns). Composite hollow fiber membrane contactors were tested for the separation of a CO₂/N2 mixture with an aqueous solution of MEA. Capture ratios achieved by composite hollow fibers are similar to those measured for microporous membranes and the dense layer prevents from wetting problems. Simulations based on 2D modeling of the mass transfer, show that the performances of composite hollow fiber membrane contactors, under operating conditions close to the industrial case, can lead to an intensification factor up to 6 compared to packed columns
