Texto completo da fonteAnaerobic digestion (AD) is a biological process capable of converting a wide variety of organic residues such as biowastes, agricultural residues and energetic crops into renewable energy (biogas) and a fertilizing product (digestate) rich in macro/micro nutrients. In recent years, the number of anaerobic digestion plants in France has risen considerably from around 300 units in 2013 to 1494 in 2023. The management of a growing volume of digestate and the environmental concerns associated with its land application are motivating the search for new valorization pathways. In this context, this thesis focuses on cyanobacteria culture as an innovative strategy for treating both liquid digestate and biogenic CO2 coming from AD, while producing a new biomass of interest at the same time. Due to its complex composition, digestate often needs to be diluted with water to reduce its toxicity for microalgae and cyanobacteria growth. In the first study, geothermal water was investigated as a substitute for fresh water to reduce the environmental footprint of the cultivation process. Four digestates from industrial plants were sampled and tested for A. platensis cultivation using several dilution factors and two types of water (demineralized vs. geothermal). Laboratory tests showed that the use of geothermal water did not significantly affect A. platensis growth profiles compared with demineralized water. The results were then validated in 6 L photobioreactors, incorporating pH regulation by CO2 injection. Productivities ranging from 81 to 136 mg/L/d were achieved during these assays.The second study explored the digestate pretreatment by ion exchange process to reduce its toxicity and decrease the required water for preparing culture media. Zeolite, a porous crystalline aluminosilicate material with high affinity for ammonium, was tested at laboratory (0.45 L) and at pilot (15.5 L) scales using packed adsorption columns. After 24 hours of treatment with 0.5 kg/L of zeolite, the initial ammonium concentration of 2250 mgN/L in the digestate was reduced below 120 mgN/L corresponding to a treatment efficiency of 95% and an average adsorption capacity of 4.1 mg/gzeolite at both scales. A. platensis cultures demonstrated the possibility of considerably reducing the dilution rate from 20x with the untreated digestate to 1x (no dilution) for the treated digestate. The scale-up experiment demonstrated that cultivation in 6 L photobioreactors using the treated and undiluted digestate was feasible. However, further optimization is necessary to maximize biomass productivity (33 mg/L/d) and nutrient assimilation, such as ammonium uptake where only 53% of removal was observed.All the results obtained in this thesis were used to set up digestate pre-treatment and A. platensis cultivation trials under outdoor weather conditions. A total of six treatments with zeolite (250 g/L) were carried out on a pilot scale to treat 53 L of digestate, showing efficient repeatability between treatments with an average ammonium removal of 81 ± 4%. As part of this study, two types of 100 L open (raceway) and closed (bubble column) reactors were studied and compared over 150 days of cultivation in an experimental greenhouse based in the South-West of France. Following this, digestate-based cultures were compared with conventional synthetic culture medium and two cultures strategies were investigated using fresh or acclimated inoculum in batch to batch systems. The systemic use of fresh A. platensis inoculum during repeated batches resulted in higher and more repeatable biomass productivities than with acclimated inoculum. In addition, open reactors led to an important loss of water due to evaporation throughout the experiment, accounting for 27± 9%Vtot. Finally, biomass productivity of 10 ± 3 mg/L/d were obtained in both reactors using zeolite pretreated digestate diluted 5 times with geothermal water

Texto completo da fonteThe presented work is focused on the study of a solar combisystem which meets domestic hot water and heating-cooling building energy needs. Solar heat is used as a priority for domestic hot water heating and when the preset water temperature is reached, excess solar energy is injected into the ground via boreholes. Solar energy can also be used to heat directly the building thanks to a direct solar floor. This system has the advantage of contributing to balancing the ground loads, increasing the operating time of the solar collectors and preventing overheating problems. This solar combisystem has been installed in a 180 m2 private residence. An experimental study, which has started 18 months ago, shows that the process is operational. The total electric consumption of the process (heat pump's compressor, domestic hot water extra heating, circulation pumps) has a value of 26 kWh/m² for the two heating seasons. The experimental study shows that the injection of heat into the ground has low impacts on the yearly energy balance of the process. Simulations of the numerical model of the process, developed with the TRNSYS software, shows that combined solar thermal collector with ground-coupled heat pump is not interesting for individual houses in term of performances. Nevertheless, using solar energy to reinject heat into the ground is a good solution for public buildings and tertiary sector for which the borehole heat exchangers concentration in the ground is more important. The process has been simulated in a public building (36 apartments, 96 occupants). These simulations show that if the solar heat injected into the ground is fewer than 45% of the heat extracted, there is a risk to freeze the water contained in the refill material and in the ground. If the cooling function of the heat pump is not used, 300 m² of solar thermal collectors allow to reinject into the ground 78% of the heat extracted and the risk of freezing is avoided. This surface of solar thermal collectors allows to stabilize the long term performances of the heat pump (diminution of the heat pump's COP of 6% after 20 years). This surface is oversized by 3 with respect to the domestic hot water requirements alone

Texto completo da fonteIt is important to know the subsurface thermal conductivity and the groundwater flow parameters (i.e. its velocity and orientation) when sizing a geothermal borefield. This master’s thesis presents a methodology and the conclusions of a numerical analysis of a novel thermal response test (TRT) concept for vertical geothermal heat exchangers. This configuration of TRT is able to measure both the hydraulic and the thermal properties of the ground. The main objective behind this work is to validate the concept and then to develop an efficient methodology to obtain from the thermal response of the TRT an estimation of the ground thermal conductivity along with the velocity and the orientation of groundwater flows. To achieve this, a numerical model of borehole was built using the finite element method. This model was then used to simulate the thermal response for various conditions. From these simulations, it has been possible to demonstrate the potential of the concept and to elaborate methodologies to find the desired properties. A graphical method is first presented. Following that, inverse problem techniques were applied to get a second measurement methodology. Results show that the suggested TRT is able to find the parameters in most of the cases.

Texto completo da fonteThermodynamic data of hydrated phyllosilicates, in particular clay minerals are not well known. The stability fields of these minerals are not well determined; following some authors they even do not exist. We have developed an experimental approach, in which a sequence of local equilibrium states between a fluid and minerals take place in a closed gold cell along a strong thermal gradient. The experiments were conducted in the chemical systems : Mg-Al-Si-H2O (MASH), K-Al-Si-H2O (KASH), and K-Mg-Al-Si-H2O (KMASH). The sequences of crystallization observed along the thermal gradient are the same if one exchanges the position of the cells containing the initial reacting materials with respect to the thermal gradient end-members. The crystallization sequences correspond to local equilibrium states. Following the temperature increase (from 200 to 350ʿC) one observes the following sequences : dioctahedral smectite ? trioctahedral smectite; kaolinite ? donbassite ? trioctahedral chlorite; smectite ? illite ? muscovite ; or even kaolinite ? illite + smectite ? donbassite ; commonly observed in hydrothermal systems. They allow to develop a thermodynamic model for hydrated phyllosilicates, taking into account their hydration state as a function of temperature. This model shows the stability fields of clay minerals between 200 and 350ʿC. The chemical and mineralogical dynamics showed in these experimental systems has been applied to predict the possible dissolutions and/or precipitations which may take place between the circulated hot fluid and the geothermal granitic reservoir in the geothermal system at Soultz-sous-Forêts. These processes may affect the duration of the geothermal reservoir, as a function of evolution in the morphology of the porosity. Our experimental approach shows that feldspars and smectites are forming the major part of the total volume of silicates which may precipitate in addition to carbonates already described in previous studies
