Abstract: Process and device for regeneration of a used absorbent from a desulfurization zone or from the desulfurization of a gas containing sulfur oxides, comprising regeneration simultaneously with filtering of the absorbent, in a reducing atmosphere, wherein partial combustion of a regeneration gas is also carried out upstream from regeneration, the products of the partial combustion being mixed with the used absorbent prior to the regeneration-filtration stage. The absorbent may be, e.g., solid absorbents based on magnesium oxide. The regeneration gas may be hydrogen sulfide and/or a hydrocarbon. For example, H2S can be partially combusted and the products of the partial combustion, including H2S, H2, SO2 and sulfur, mixed with the used absorbent prior to the regeneration-filtration stage.

Abstract: The invention concerns a method for analyzing a sample of a complex molecule relatively to a reference batch of the same complex molecule. Said method is characterized in that it consists in breaking up the complex molecule into at least two molecular sub-entities; in determining, on the basis of the atomic sites of said products of the breakup involved in the breakup reactions, the isotope(s) to be analyzed; and in establishing, for at least part of the breakup products, their isotopic profile; and in comparing the isotopic profile of the products of the breakup with the isotopic profile of the raw material(s) previously indexed and/or with the isotopic profile of the reference complex molecule subjected to the same breakup reactions. The invention is useful for detecting counterfeiting in manufacturing processes.

Abstract: The invention consists of an application of radiant burners to furnaces for heat treatment of hydrocarbon feedstocks in which the feedstock that is to be treated circulates inside an exchange tube bundle that receives the heat that is emitted by the burners essentially by radiation and for which a strict monitoring of the temperature profile along the exchange bundle is necessary. Applied to steam-cracking furnaces, the invention makes it possible to increase the propylene yield to iso ethylene yield. It also makes it possible to increase the compactness of the furnace and the longevity of the exchange bundle and to reduce the NOx emissions.

Abstract: The invention relates to a method for decreasing the level of carbon dioxide present in the fumes discharged by a power generator burning a mixture of a combustive agent and of a fuel containing hydrocarbons, wherein a gaseous mixture comprising at least part of said combustive agent and at least part of said fumes is compressed, all or part of the carbon dioxide present in the compressed gaseous mixture is eliminated by absorption, a fuel is mixed with the gaseous mixture, the resulting mixture of fuel and gaseous mixture is burnt and the fumes from the combustion process are expanded. The invention also relates to a power generator for implementing said method.

Abstract: The invention relates to a thermal generator comprising a furnace tube (2) wherein a fuel is burnt, recombustion means (14, 15) for reducing the nitrogen oxides content present in said fumes and means (3) for recovering the heat of the fumes resulting from said combustion.

Abstract: The present invention relates to a device for injecting a liquid fuel into a pressurized air flow (7), in particular for a combustion chamber, comprising a hollow cylindrical body (10) of longitudinal axis (YY′) delimiting a substantially cylindrical central volume (11), fluid veins (12) substantially radial in relation to the longitudinal axis of body (10) and arranged on the periphery of said body to allow passage of said flow, and axial fuel injection pipes (5) arranged inside said fluid veins and connected to at least one fuel inlet (3) by at least one supply point (16). According to the invention, pipes (5) are pierced with openings (9) that open onto central volume (11) of said body (10) and which are oriented substantially in the direction of the flow in fluid veins (12).

Abstract: The invention relates to a method for regenerating a used solid absorbent from a desulphurization zone wherein partial combustion of a regenerating gas, regeneration of the absorbent by contacting, in a chamber, said absorbent with the gas effluents derived from the combustion, cooling the gas mixture resulting from regeneration to a temperature higher than the liquid sulphur formation temperature, and filtering the cooled mixture to separate the solid particles of regenerated absorbent from the gas fraction of said mixture is carried out. The invention also relates to an installation for implementing said method.
