Full textIn order to reduce greenhouse gases emissions, CO2 release due to human activities should be better controlled. CO2 capture by adsorption is considered as one ot the potential options. In this work, different commercialized activated carbons (AC) were evaluated as a potential adsorbent for CO2 capture by pressure modulation and were compared to commercialised zeolites. Adsorption isotherms, materials aging and gas separation were determined and evaluated. Relations between physical properties and adsorption capacities are founded. These relations were used in order to determine the adsorbent demonstrating the best adsorption regeneration capacities depending on the operating conditions applied. CO2 transportation from production places to storage locations is presently accomplished by liquid or supercritical phase, which generate large costs and emissions. This final part of this work considers the possibility to transport CO2 in adsorbed phase (with considered materials) and analyzes its cost as a function of transported quantities, transport conditions and transportation means. CO2 transport by ship in adsorbed phase on small distances was seen as being competive to ship transportation in liquid phase. The CO2 emissions generated by CO2 transport in adsorbed phase were evaluated in all cases (transportation means, distances, conditions) to be much smaller than the ones generated by liquid phase transport

Full textOrgano-mineral associations play a key role in the long-term sequestration of organic matter in forest soils. However, knowledge about the contribution of the different types of organo-mineral associations and the microbial processes involved in soil organic matter stabilisation is scant. To solve it, stable isotope techniques have been combined with the sequential density fractionation of organo-mineral associations. Isolated fractions were investigated in field and in lab, at different temporal (from 8 hours to 12 years) and spatial scales (macro-, submicron- and molecular scales).Four types of organo-mineral associations were distinguished: plant debris with little mineral attached, plant aggregates, microbial aggregates and mineral grains. Isotopically labeled beech leaf litters were tracked at a decadal time-scale to reveal transfers in between organo-mineral associations. Both litter-derived carbon and nitrogen entered the soil as plant fragments to progressively pass through plant and microbial aggregates. Aggregates appeared particularly meaningful for the stabilisation of litter-derived carbon and nitrogen at a decadal time-scale. Little of the litter-derived carbon and nitrogen was found quickly stabilized to mineral grains. Microbial activities appeared as a major controlling factor for the evolvement of organo-mineral associations, responsive for the transfers of litter-derived carbon and nitrogen. Indeed, plant debris colonized by microorganisms are progressively trapped into plant aggregates. As decomposition proceeds, plant aggregates disrupt into denser microbial aggregates. These aggregates are loaded with lesser organic matter, but enriched in stable microbial materials.Stabilisation by soil microorganisms has been studied at the macro-, submicronand molecular- scales, using mostly NanoSIMS and LC-IRMS. Microbial stabilization operated (i) directly through immobilization in microbial cells and, (ii) indirectly through large production of extracellular microbial products. By calibrating the NanoSIMS for accurate C/N ratios, extracellular microbial products have been shown to be stabilized onto organo-mineral associations without apparent control of the mineral-attached organic matter chemistry. The incorporation of 13C tracers into amino sugars, biomarkers of bacterial and fungal biomasses, revealed that living microorganisms grow where the resource is, but accumulate in microbial aggregates. Microbial biomasses moved from plant debris to microbial aggregates, likely along with the transfers of decaying litter residues as described above.This work points aggregates as meaningful organo-mineral associations for the sequestration of litter-derived carbon and nitrogen at the decadal time-scale. It also revealed the role of microorganisms in the transfers and stabilization of litterderived carbon and nitrogen within organo-mineral associations

Full textCO2 underground storage as an option for reducing greenhouse gases emissions consists of trapping industrial CO2 and injecting it into deep geological formations such as saline aquifers and hydrocarbons reservoirs. This study aims at assessing leakage processes and evaluating storage capacities. To this end, two leakage phenomena were considered, caprock capillary breakthrough and diffusional transport. The former involves interfacial properties of the brine/CO2/mineral system: brine/CO2 interfacial tension and rock wettability under dense CO2. Chapter one presents a series of IFT measurements performed at temperatures and pressures up to 45 MPa-110°C. Results show a great decrease of IFT with pressure in the 0-to-20 MPa range beyond what it tends to stabilize at values in the order of 25-30 mN. M-1. Chapter two deals with rock wettability. Dynamic contact angles were measured on muscovite mica and quartz up to 10 MPa. Results highlight an alteration of wettability with pressure that was accounted for by means of a DLVO based model. Direct capillary entry pressures on a clay stone sample are proposed in chapter three. Diffusion, is treated in chapter four. We used the Taylor dispersion method to measure D up to 40 MPa. Results indicate low values in the order of 2. 10-9 m2. S-1. Chapter five discuses the consequences of the previous parameters in terms of storage capacity

Full textTo limit emissions of greenhouse gases in the atmosphere, CO2 geological sequestration appears as a solution in the fight against climate change. The development of reliable monitoring tools to ensure the sustainability and the safety of geological storage is a prerequisite for the implementation of such sites. In this framework, a geochemical method using noble gas and carbon isotopes geochemistry has been tested on natural and industrial analogues. The study of natural analogues from different geological settings showed systematic behaviours of the geochemical parameters, depending on the containment sites, and proving the effectiveness of these tools in terms of leak detection and as tracers of the behaviour of CO2. Moreover, an experience of geochemical tracing on a natural gas storage has demonstrated that it is possible to identify the physical-chemical processes taking place in the reservoir to a human time scale, increasing interest in the proposed tool and providing general informations on its use

Full textThe project of this thesis relates the impact of initial variability of geological reservoir on the underground storage of CO₂. We use as a starting point the natural basins such as the carbonated Dogger of the Basin of Paris and sandy reservoirs of Ravenscar (the North Sea). Each of the rebuilt model reservoir was defined by the list of its minerals (calcite, dolomite, chlorite, potassic feldspath, kaolinite, quartz for example for the carbonate reservoir) and by his petrophysical properties (porosity and permeability). The variability of these parameters was simulated using multivariable geostatistic methods operating on their range, stage, and thresholding. We defined important operational parameters to summarize the main properties of storage (namely the quantity of carbon stored in the reservoir, the quantity of carbon precipitated in the form of dolomite, quantity of carbon evacuated by the mobile aquifer, quantity of carbon contained in the water of the reservoir as well as the variation of porosity in the reservoir). Deterministic responsive transfer simulations were then made following different storage scenarios: (a) case of the injection of the initial CO₂ in the tank that has enabled us to set the initial state of the tank, (b) case of an aquifer mobile moving in the tank containing saturated CO₂, and (c) the case of an acidic water moving in a tank containing an neutral aquifer). We have subsequently sought to study the influence variability on operational parameters storage settingsWe have thus highlighted that, compared to the homogeneous case, the heterogeneous field promotes the dolomite carbon storage and decreases the amount of carbon removed by the aquifer. The effect of high petrophysical range and the impact of mobile aquifer have also been studied. Finally, we set up a model of experimental plan, to study the impact of the variability of all input data on selected answers. The effect of numerical dispersion has been studied and we demonstrated their importance in some results. The experimental plan has highlighted the importance of dolomite spot on the carbon stored

Full textThe set-up of oxy-fuel combustion with flue gas recirculation raises questions about the design of adapted burners. The separation of the oxidant (O2) and inert gas (flue gas) allows either their injection with premixing of both flows, in burners with similar design than those used in classic air combustion, or separated injection, with the possibility to modify independently the injection parameters for each flow. Both injection strategies are studied and compared in the frame of a simplified academic study, led on CH4-fed multi-coaxial 25 kW burners, with O2 and CO2 (replacing the recirculation gases). These burners are composed of three to four coaxial injections, depending on the strategy: respectively CH4/ O2/(CO2+O2) for premixed strategy, and CH4/O2/CO2/O2 for separated injection strategy. A small primary oxy-fuel flame is maintained, and stabilizes behind the methane lip: four main flame types are observed thanks to chemiluminescence. The flame is continuous and homogeneous in terms of intensity (A type) for premixed burners. For separated injection burners, it may exhibit a localized decrease of intensity between the primary and the secondary flame (A’ or C type), or the secondary flame is lifted far above the primary oxy-fuel flame (B type). Mixing mechanisms leading to these structures are analyzed with PIV, and show that flame stability is favored by recirculation zones, by a small CO2 flow or co-flow (CO2+O2) velocity, associated to a large velocity ratio UO2/UCO2. The large velocity gradients favor the mixing and provide a stable flame, with controlled and acceptable thermal fluxes and temperatures distributions, and exhaust gases composition
