Ayoub, Elie. "Caractérisation des effluents d’expérimentations EOR (Enhanced Oil Recovery) grâce à des techniques de microfluidique analytique". Thesis, Sorbonne université, 2019. http://www.theses.fr/2019SORUS017.
Testo completoChemical Enhanced Oil Recovery (cEOR) is one of the methods used to meet the growing demand for oil. Among these methods we can find the surfactant flooding. Surfactant flooding consists in injecting an aqueous formulation, containing surfactants, in order to obtain ultra-low interfacial tensions (typically <10-2 mN / m) between water and oil and thus mobilize the oil trapped by capillary forces in the reservoir. Generally, a salinity-scan is performed, in the laboratory, to determine the optimal salinity (S*) of the formulation which corresponds to a minimum of interfacial tension. The optimal formulation is then evaluated through a "coreflood test" which is carried out on a rock sample under conditions (Pressure and Temperature) very close to those of the reservoir. The performance of a coreflood experiment is evaluated by determining the amount of oil recovered and the amount of surfactants retained in the reservoir (by adsorption). These two parameters are of prime importance to confirm the economic viability of the cEOR process. Currently, coreflood effluents are collected in tubes throughout the experiment and the analyses are performed offline. The quantity of oil recovered is measured by volumetry (water/oil ratio in the tubes) or RMN. Surfactants are dosed in the aqueous phase by hyamine assay or by HPLC. It is noteworthy that these analyses may be difficult to carry out experimentally since the effluents may contain emulsions that are difficult to separate. Moreover, it is unclear whether all surfactants are well in the aqueous phase, or whether they are partly trapped in the oil phase. To overcome these difficulties and quantify the two important parameters of coreflood experiments, we have developed an integrated online measurement technique based on microfluidic tools. The experimental setup includes: a dilution chip to transfer the surfactants in the aqueous phase, an observation chamber to quantify the water / oil ratio of the effluent by image analysis, a membrane-based separation device, and an on-line UV-visible spectrometer for surfactants quantification. This experimental setup was successfully validated with model fluid mixtures (decane, NaCl brines and sodium dodecyl benzene sulfonate SDBS), and was evaluated on real systems (crude oil and industrial surfactant formulations). Finally, it was tested under representative conditions of coreflood experiments, being directly connected to the output of a coreflood test. The results obtained during this thesis work proved the effectiveness of the experimental setup to facilitate the quantification of the surfactants in the effluents of the coreflood experiments, and the volume of oil recovered. They showed a clear improvement compared to the quantification protocols currently applied

Testo completoIn the field of cosmetics, many raw materials are used and natural extracts from plants represent a large part of them. Plant extracts can have different activities: antioxidants, anti-aging ... However, their color mainly due to pigments can be an obstacle to their use because they can have stability problems. Their degradation results in a change of color which may be incompatible with their formulation.The objective of the thesis is to find selective conditions in order to extract compounds of interest without pigments (mainly chlorophylls).Initially, a study of the stability of chlorophylls allowed identification of extraction and storage conditions in order to identify and quantify native chlorophylls and their degradation products according to the different operating approaches. This made it possible to identify extraction and storage conditions limiting their degradation. Secondly, modeling was carried out, mainly by supercritical chromatography, to determine selective extraction conditions, with supercritical fluids, of antioxidant molecules (carnosic and rosmarinic acids) on the one hand and chlorophyll pigments on the other hand from rosemary, without the need for numerous extraction experiments. Finally, a sequential supercritical CO2 extraction using conditions determined by the previous model was developed. An online extraction/chromatography system was developed to support this development through extraction kinetics studies. This extraction allowed the realization of four fractions respectively rich in carotenoids, carnosic acid, rosmarinic acid and chlorophylls
