A gas burner for burning a gas with a low calorific value. The gas burner may be for burning a synthesis gas issuing from the gasification of biomass.

Lean gas burner

A fixed bed gasification system to convert solid organic matter (also called biomass), into synthesis gas. This gas can be burned in an engine, turbine, oven or boiler, which makes it possible to valorize the thermal energy that it harbors.

Method and apparatus for fixed bed gasification

A system for energy storage, in particular for mechanical energy, including a system for quasi-isothermal compression of a gas via a hydraulic fluid. The mechanical energy stored is then released by quasi-isothermal expansion of the gas. The system is also configured to store electrical energy, in particular from intermittent sources such as photovoltaic or wind energy. The storage of excess electrical energy can also be considered for use during consumption peaks.

A cogeneration method and device by turbine, particularly by gas turbine, uses a compression section, at least one expansion section, and a combustion chamber. A combustion agent including oxygen is compressed in the compression section; in the combustion chamber, one combustion step is carried out under pressure with a mixture of combustion agent compressed with a fuel; at least some of the hot gases obtained by pressurized combustion are used to effect an exchange with an external facility; and at least one postcombustion step is carried out of a mixture of hot gases coming from combustion with a fuel, prior to the exchange, and at least one other postcombustion step of a mixture of hot gases, coming from the exchange, with a fuel, in order to obtain hot gases that are sent to the expansion section.

Cogeneration method and device using a gas turbine comprising a post-combustion chamber

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, HS can be partially combusted and the products of the partial combustion, including HS, H, SOand sulfur, mixed with the used absorbent prior to the regeneration-filtration stage.

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.

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.

Process for generating heat to reduce the emission of oxides of sulphur and reduce adsorbent consumption

Process for recovering a solvent from a gas coming from a treating process using the solvent, the gas having a low temperature Ta and a high temperature Td, the difference Td-Ta being sufficient to carry out an adsorption step and a desorption step. The process is characterized in that/ a) a first solvent-containing gas stream is sent to an adsorption step, this gas being at a temperature Ta, at the end of this step the gas is practically solvent-free and the solvent is collected in a first adsorber, b) a second gas stream at a temperature Td, this gas being solvent-free, is sent to carry out desorption of a second adsorption means loaded with solvent during a previous step a), and c) the solvent is sent at least partly to a step of the treating process using the solvent.

The invention is a device for sampling and/or injecting a fluid which evolves according to a reversible reaction, that enables the fluid to be restored to its initial state. The device inside a fluid sampling enclosure produces a counterpressure value necessary for restoring the fluid to its initial state without causing a change in its composition.

Process for selective hydrogenation of a hydrocarbon cut containing at

Described is a process for degasolining by refrigeration of a gas containing condensable hydrocarbons, which is effected in the presence of methanol to avoid the formation of hydrates, said process making it possible to at least partially recover the methanol entrained in the gas, by washing same by means of a liquid hydrocarbon fraction. The process described thus makes it possible to avoid having to compensate for the loss of methanol by a continuous make-up, as is the case with conventional processes. It accordingly enjoys enhanced levels of performance and economy.

A method of treating a fluid containing at least methane and at least one acid gas and producing the acid gas or gases in liquid form. The method includes a step of regenerating the solvent, operated at a pressure whose value is at least equal to the bubble pressure of the mixture of acid gases produced in liquid form, a step in which the gaseous fraction from the regeneration step is rectified in a contact zone by separating at least some of the solvent from the gaseous fraction, a step in which the gaseous fraction from the modification step is cooled to a given temperature to cause at least some of the gaseous faction to condense forming at least one liquid fraction enriched with liquid acid gases and a step during which the liquid fraction of gases is separated from the remaining gaseous fraction.
