摘要:
After passing into reaction section R, the hydrocarbon feedstock C mixed with hydrogen H is expanded in device D. The expansion is brought about by a single-phase turbine until a gas volume ratio of 5% is reached, then expansion is brought about in a two-phase turbine of the rotodynamic type.

A skin and a method for restructuring the inner surface of a tube of long length includes manufacturing a skin, in a material with expansion rate greater than 50%, the external surface of which includes a restructuring print determined in order to take into account the longitudinal and radial expansions that the skin is going to undergo, and as a function of the desired final surface state for the tube to be restructured, longitudinally expanding the skin up to the required length for the tube, longitudinally introducing expanded skin inside tube to be restructured, and radially expanding the skin to realize the restructuring.

The fumes from gas turbine TG are cooled by heat exchangers E1, E2, E01, E02 and E03 and compressed by compressors C1 and C2. The cold and high-pressure fumes are depleted in carbon dioxide in treating plant 10. The fumes depleted in carbon dioxide are heated by heat exchangers E1 and E2, and expanded by turbines T2, then T1. The energy recovered in form of heat in exchangers E01, E02 and E03 is converted into mechanical energy by the engine cycle used by turbine T, condenser E and pump P. The mechanical energy is available at the shaft of turbine T.

A compression-pumping system for a multiphase fluid (GLR) includes a compression section, a pumping section, a shaft and a separator. The compression section is sealed off from the pumping section, and the pumping section and the compression section are included in the same enclosure and mounted on the same shaft. The compression-pumping system is associated with a liquid level control system situated at the level of the separator.

The device 1 for determining the hydraulic roughness of the internal surface of a pipe 2 has a trolley 4 with wheels 3. Drum 5 is mounted to be rotationally movable on trolley 4. The roughness is determined by measuring the resisting torque of drum 5 or by measuring the dynamic pressure given by Pitot tubes 11. The translationally movable trolley 4 has the advantage of being able to measure the roughness at different points in pipe 2.
摘要:
The gas to be processed, flowing in through line 10, contains impurities. This gas is contacted in column C1 with a solvent flowing in through line 18. The scrubbed gas is discharged through line 19. The impurity-laden solvent recovered through line 12 is regenerated by expansion, then by distillation in column C2. The invention proposes carrying out expansion by means of two-phase turbines T1 and T2.
摘要:
A gas compression device for compressing and separating a gas including a liquid phase and a gas phase, includes at least one inlet pipe for the wet gas, at least one compressed gas outlet pipe, a shaft and several compression stages. The device includes at least one compression stage suited for separation of the liquid phase and of the gas phase, one or more pipes designed for discharge of an essentially liquid phase resulting at least partly from the separation performed in a suitable compression stage. The device can be used for wet gas transportation in the petroleum field.
摘要:
The invention relates to a device which determines aerodynamic characteristics of a wall. The device comprises a drum secured to a shaft, an enclosure defining with the drum at least one test zone (10a; 40a), a test fluid delivery line communicating with this test zone and means which determines a parameter representative of the friction factor of the fluid in the at least one test zone. The at least one test zone has a determined width 1 or gap width, for a given rotating speed of the drum and a test fluid having known characteristics (visosity, density . . . ), so that the fluid has a turbulent flow in the vicinity of the wall(s) to be tested, the turbulent flow corresponding to a given Reynolds value Re.
