Abstract:
A fail safe container and container insert are disclosed. A flexible container insert may convert energy from a catastrophic event, including but not limited to collisions, accidents, impacts, pressure container failures or explosions such as detonations, or other catastrophic incidents, into a stretching of an internal structure of a fail-safe container insert to minimize or prevent failure of the container insert and/or the container. The stretchability of the container insert may accommodate both temperature and shape changes to protect a container, including but not limited to a pressure vessel, from rupture or other failure. Accordingly, a container insert may be considered self-healing in that it may absorb the effects of catastrophic events to prevent failure, may return to a generally previous condition, and/or may seal or otherwise reduce or minimize breaches when they do occur.
Abstract:
A system that can offload compressed gas from a storage tank to a customer site. The system can have a fluid circuit that is configured to fit within a container structure, like a trailer, for mobility to remote locations. This fluid circuit can include a transfer unit to automatically switch between tanks. The transfer unit can couple with a heat exchanger. Downstream of the heat exchanger, the fluid circuit can reduce pressure of fluid from the tanks through multiple pressure reduction stages. Each of the pressure reduction stages can include a throttling device, for example, a pilot-type fluid regulator and a control valve assembly. The throttling device may be selected to maintain flow of fluid at least at, e.g., 35,000 scfh, in accordance with pressure drops in the incoming fluid from the tanks.
Abstract:
This invention relates to a multiple containment unit of compressed gas cylinders, in particular for marine transport, comprising: - a support frame (10) with support base (11) and side containment structures (12) that define an inner containment volume (13); and - cylinders (20) for containing compressed gas connected to said frame in order to maintain a stable position therein. The support base has a plurality of support feet (14) designed to be rigidly anchored to a portion of a means of transport. The support base is connected to each of said support feet by means of an elastic joint (15). The set of elastic joints creates a discontinuity in the transmission of the stresses and deformations between the support feet (14) and the support base. These elastic joints are dimensioned to allow relative displacements between the feet and support base on a plane parallel to the base itself, damping displacements orthogonal to that plane.
Abstract:
A method for releasing a fluid from a pressure vessel assembly, the method including the steps of providing:—a pressure vessel; a piezo electric device; and an electric field generator; arranging the piezo electric device in a sealed relationship with a part of the pressure vessel, thereby providing the pressure vessel assembly, providing a fluid contained within the pressure vessel assembly under pressure, and using the electric field generator to apply an electric field to the piezo electric device, such that the piezo electric device fails, thereby releasing the fluid from the pressure vessel assembly.
Abstract:
The invention relates to a method for optimizing the cryogenic pressure tank (2) fill level which can be achieved during a refill in a motor vehicle, in particular a cryogenic pressure tank (2) in a motor vehicle. A heating device (3) for heating a gas in the pressure tank (2) has at least two modes, namely a regular operating mode, in which the heating device (3) heats the gas in the pressure tank (2) such that a specified pressure of the gas in the pressure tank (2) is reached, and a continuous operation mode in which the heating device (3) constantly heats the gas in the pressure tank (2) such that the pressure of the gas in the pressure tank (2) rises above the specified pressure. The method has the following steps: detecting the density of the gas in the pressure tank (2); comparing the detected density of the gas in the pressure tank (2) with a specified density value; and if during the comparison it is determined that the detected density falls below the specified density value, either operating the heating device (3) in the regular operating mode or switching the heating device (3) from the regular operating mode to the continuous operation mode, in particular on the basis of a specified path to the destination of the motor vehicle and the service stations provided on the specified path to the destination for refilling the pressure tank (2) with gas.
Abstract:
The invention relates to a tap for a pressurised fluid tank including a coupling (7) for filling and optionally drawing off, the coupling (7) forming a recess on the body (1) that is intended for receiving a filling tool, the circuit (3) of the tap including: an isolating valve (8) and a pressure reducing valve (9), the pressure reducing valve (9) including a mechanism comprising a piston (10) that is translatably movable in a predetermined longitudinal direction (A) relative to a seat in order to open or close the circuit (3), the piston (10) being biased by a return member (11) towards the seat in a closed position of the circuit (3), an upstream end of the piston (10) leading into the bottom of the recess defined by the coupling (7), the upstream end of the piston (10) being located at a predetermined reference distance (L2) relative to the reference surface (13) in the longitudinal direction (A), characterised in that the reference distance (L2) is between 17 and 30 mm and preferably between 22 and 27 mm.
