摘要： A process for separating ethane and ethylene from a hydrocarbon steam-cracking effluent is described. Effluent (1) is absorbed in an absorption column by a cooled solvent (9). At the bottom of the column, the liquid phase that contains the solvent and the C2+ hydrocarbons is recovered and hydrogenated (15). The hydrogenation effluent that contains the solvent is introduced into a first distillation column (16). Ethane-ethylene mixture (17) is drawn off laterally from the column, and a phase (19) that contains the solvent and hydrocarbons with at least 3 carbon atoms is drawn off at the bottom of the column. This phase (19) is separated in a second distillation column (22), and C3+ hydrocarbons and, at the bottom of the column, regenerated solvent (26) that is cooled and that is recycled (9, 52) in the absorption column are collected.

摘要： A process and a device for separating ethane and ethylene from a hydrocarbon steam-cracking effluent is described. Effluent (1) is absorbed in an absorption column (7) by a cooled solvent (9). At the bottom of the column, liquid phase (12) that contains the solvent and the C2+ hydrocarbons is recovered and hydrogenated (15). The hydrogenation effluent that contains the solvent is introduced into a first distillation column (70) where the solvent is regenerated. The solvent is cooled and recycled at the top of absorption column (7). The C2+ hydrocarbons are collected at the top, and a condensed liquid phase is distilled in a second distillation column (77) to recover a C2 fraction that consists of ethane and ethylene.

摘要： The present invention relates to a gas-turbine combustion chamber comprising at least a zone (11) referred to as pilot combustion zone into which at least a first pilot fuel injection means (3) and an associated first oxidizer injection means (4) open; a main combustion zone (12) into which at least a second main fuel injection means (7) and an associated second oxidizer injection means (8) open, all of it being maintained under a pressure P1 inside an enclosure (14). According to the invention, said chamber further comprises a mechanical means (15-19) for controlling the second flow of oxidizer, which reacts to the pressure difference between the inside (P1) and the atmospheric pressure (Po) outside enclosure (14), said pressure difference being directly linked with the engine speed.

摘要： A combustion chamber of a gas turbine working on liquid fuel includes a tubular enclosure (2) having at least one pressurized air inlet, a liquid fuel injection means (6) positioned on or in proximity to the longitudinal axis (XX′) of the tubular enclosure, and an outlet to the turbine. The fuel injection means (6) includes a series of orifices (62) arranged so as to create separate fuel jets, the jets being arranged in the direction of the generatrices of a cone with an angle ranging between 30° and 60° at the vertex thereof. The chamber includes at least two types of pressurized air inlets placed close to each other, the first one (7) taking in the air helically around the longitudinal axis of the combustion chamber, the second air inlet (8) being tangential to enclosure (2) so as to create, around the fuel jets, counterrotating flows intended to improve mixing of the air and of said fuel. The assembly preferably works at a pressure ranging between 2 and 30 bars and with a fuel/air ratio ranging between 0.4 and 0.8.
