Abstract: Method for treating a gaseous feedstock containing molecular oxygen and one or more volatile compounds, which method comprises the following steps: a) bringing said gaseous feedstock containing molecular oxygen and one or more volatile organic compounds into contact with a monolith comprising silica and titanium dioxide, said monolith comprising a type-I macropore volume, of which the diameter of the pores is greater than 50 nm and less than or equal to 1000 nm, of between from 0.1 to 3 ml/g, and a type-II macropore volume, of which the diameter of the pores is greater than 1 μm and less than or equal to 10 μm, of between from 1 to 8 ml/g; b) irradiating said monolith with at least one irradiation source producing at least one wavelength lower than 400 nm in order to convert said volatile organic compounds into carbon dioxide, said step b) being carried out at a temperature between −30° C. and +200° C. and at a pressure between 0.01 MPa and 70 MPa.

Abstract: The invention is a method for the exploitation and/or monitoring of an underground formation having at least one reservoir comprising water, at least one gas species of interest and at least one atmospheric isotope of at least one rare gas present in dissolved form in the water of the reservoir. The method includes at least (1) taking at least one gas sample at the level of at least one collection of water from the reservoir, the collection being at the surface and the sampling being carried out to avoid any contamination with the air; (2) measuring at least the concentration of at least the gas species and the concentration of at least an atmospheric isotope of the rare gas in the gas sample; (3) determining the concentration of the gas species of interest dissolved in the water of the reservoir by a model which is a function at least of the concentrations of the gas species of interest and of the atmospheric isotope measured in the gas sample.

Abstract: A combustion chamber (18) of a thermodynamic cycle turbine with a recuperator, for electrical energy production, comprising a casing (56) housing a flame tube (64) with a perforated diffuser for passage of the hot compressed air, a primary zone (ZP) that receives part of the hot compressed air flow and where combustion takes place, and a dilution zone (ZD) where the burnt gases from the primary zone mix with the remaining part of the hot compressed air flow, said chamber further comprising an injection means (76) for injecting at least one fuel. The flame tube carries a flame stabilizer (82) comprising perforated diffuser (88), at least one combustion gas recirculation passage (98) and a mixing tube (94).

Abstract: The invention is a redox flow battery (1000) comprising n electrochemical cells 300 that are electrically connected in series (300) with each cell including a cathode (310) and an anode (320) that are separated by a membrane (330) and that are respectively passed through by a catholyte and an anolyte originating from a catholyte tank (110) and an anolyte tank (120). The cells are fluidically connected in parallel. The invention is also a system for decreasing bi-pass currents including means (700) for injecting a gas into the inlet ducts (401) and outlet ducts (501) of the cathode and anode of (n−1) cells to form gas bubbles; and a device (800) for removing the gas bubbles, placed, on the inlet ducts of the cathode and anode of the (n−1) cells, downstream of the means for injecting the gas and upstream of the cathode and anode of the cells.

Abstract: The present invention relates to a method for detecting the presence of gas hydrates and/or ice in a medium. The method comprises at least the following steps: measuring at least at one measurement point in said medium two characteristic values of Raman spectra corresponding to two distinct vibration modes of the OH bonds of water, and determining the ratio τ of said two characteristic values, determining the temperature T in said medium at said measurement point of said spectra, comparing ratio τ with a value τ0 corresponding to a predetermined threshold of formation of said crystals for said temperature T, and determining the presence or not of hydrate and/or ice crystals from said comparison.
