Abstract (en)
A fluid with a liquid proportion greater than or equal to 95% at a pressure P1 is expanded across a single-phase turbine to obtain a fluid with a liquid proportion less than or equal to 5% at a pressure P2. The second fluid is expanded again through a two- phase turbine to obtain a fluid at pressure P3. The two-phase turbine is a rotodynamic turbine. The single phase and two-phase turbines form a single machine with at least one single phase impulsor and distributor and at least one two-phase impulsor and distributor. The turbines, impulsors and distributors share a common shaft. Before the first expansion, part of the high pressure fluid is taken and expanded in a first device, then the rest of the fluid is expanded in a second device before entering the single-phase turbine. The low pressure fluid from the two- phase turbine is expanded in a third device. The first, second and third devices are expansion valves or turbines.
Abstract (fr)
Après passage dans la section de réaction R, la charge d'hydrocarbure C mélangée à l'hydrogène H est détendue dans le dispositif D. La détente est effectuée par une turbine monophasique jusqu'à atteindre un taux volumique de gaz de 5%, puis la détente est effectuée dans une turbine diphasique de type rotodynamique. <IMAGE>
