Abstract:
The invention relates to a protective cap for a pressurised fluid cylinder valve, comprising a hoop (1) defining a sheltered protected space, the lower end of the hoop (1) being secured to the generally annular base (2) that is intended to be mounted around the neck of a pressurised fluid cylinder. The cap is characterised in that the hoop (1) comprises a draw-formed metal sheet. The invention also relates to the corresponding method.

Abstract:
The invention relates to an installation for storage of a compressed gas, such as air, comprising a cavity (10) for containing the compressed gas, wherein the cavity (10) comprises an excavated blind hole in rock. Embodiments of the installation comprise a section (10) with a larger diameter, a pressure plug (15) or a flexible impermeable lining (13).
Abstract:
Procédé de remplissage d'un réservoir (1) de gaz via un injecteur (2), dans lequel la température T(t) moyenne du gaz dans le réservoir (1) est estimée en temps réel comme une fonction du premier degré de la température moyenne du gaz T(t-1) à l'instant précédent (t-1) et d'un coefficient d'échange chaleur kg(t-1) convectif entre le gaz et la paroi interne du réservoir (1) à l'instant (t-1), dans lequel le coefficient d'échange chaleur kg(t-1) est donné par la relation kg=(λg/Dint).Nuint dans laquelle λg est la conductivité thermique du gaz dans le réservoir, Dint est le diamètre interne du réservoir (1) et Nuint le nombre de Nusselt du gaz dans le réservoir (1), et dans lequel le nombre de Nusselt du gaz est exprimé en fonction du nombre de Reynolds (Red) relatif à la convection forcée dans le réservoir (1) et du nombre de Rayleigh (Radint) relatif à la convection naturelle interne dans le réservoir (1) selon une formule Nuint= a.Radint b + c.Red d dans laquelle a, b, c et d sont des nombres réels positifs sans dimension fonctions des dimensions connues du réservoir et de l'injecteur (diamètre, longueur).
Abstract:
A tamper-proof device (20) for compressed gas cylinder bundles comprises a belt-shaped securing section made of a flexible material which extends in the installed state over a removal valve (7) of a compressed gas cylinder bundle and prevents unauthorised removal of gas from the compressed gas cylinder bundle. Connecting sections (22, 22'), which are guided through bores (18, 19) in the support frame of the compressed gas cylinder bundle are provided at both ends of the device on the securing section. One or more predetermined breaking points (24, 24') in the securing section or the connecting sections ensure that the tamper-proof device cannot be removed from the compressed gas cylinder bundle without being damaged or destroyed in the process.
Abstract:
A system for the solid state storage of hydrogen in accordance with several exemplary embodiments is disclosed herein. The system includes a plurality of hydrogen storage containers. Each hydrogen storage container of the plurality of hydrogen storage containers has an inner chamber and an inlet. The inlet provides a pathway for introducing hydrogen gas into the inner chamber. The inner chamber having a solid hydrogen storage medium disposed therein. The system further includes an endplate manifold having a hydrogen receiving port, a plurality of hydrogen outlet ports, and a flow channel. The hydrogen flow channel is integrated into the endplate manifold. Each hydrogen outlet port is in fluid communication with the inlet of one of the plurality of hydrogen storage containers. The hydrogen flow channel provides fluid communication between the hydrogen receiving port and each hydrogen outlet port.
