Abstract:
Bag (1) for application in an external container (2) for forming a pressure vessel (2) with two separate compartments (3,4), that is manufactured from an elastic and stretchable material that is such that the bag (1) can stretch from an unstretched state to a stretched state when the bag (1) is filled with a product (9) or when the bag (1) is inflated with air, whereby the stretching of the bag (1) is reversible and whereby the stretch is so substantial that the bag (1) can be used for constructing pressure vessels (2) of diverse dimensions.
Abstract:
The cartridge (1) contains fuel in a liquid phase (8) and in a vapour phase (9) with an additive (10) in the vapour phase and a small amount of additive (11) also dissolved in the liquid phase (8). As an additive, the hydrogen can be considered. Thanks to the invention, the power of the fastening tools operating with such a cartridge can be lowered.
Abstract:
A fluid tight container for storage and transportation of high pressure compressed gas, the container (110) having a first connection (112) which serves as an inlet and outlet for gas to be stored in the container, a flexible impermeable membrane (111) dividing the container into a first portion (115) for gas and communicating with the first connection, and a second portion (116) for liquid, in which the second portion communicates with a second connection (114) for introducing or withdrawing liquid from the second portion. The invention facilitates the charging and discharging of the gas at a controlled pressure.
Abstract:
In one arrangement there is provided a method of charging a fluid vessel (10). The vessel (10) comprises a rigid outer container, an expandable bladder (8) within the outer container in fluid communication with a release valve (9) of the fluid vessel (10). A cavity separates the rigid outer container and the bladder and the method comprises the steps of providing a first fluid (5a) to the cavity, for providing external pressure to the expandable bladder (8), and subsequently providing a second fluid (5) to the bladder (8) prior to use of the fluid vessel (10).
Abstract:
The invention relates to a method for producing a thermoplastic polymer bladder (2) for sealing the gases in a type IV composite reservoir (1), and to a type IV reservoir that can be obtained by said method. The inventive method consists of a step for polymerising a precursor monomer of said thermoplastic polymer into said thermoplastic polymer in a rotating mould which is heated to a working temperature higher than or equal to the melting temperature of the monomer and lower than the melting temperature of the polymer, in such a way as to form the inventive bladder (2) by polymerisation of the monomer, coupled to a rotational moulding, and without the obtained thermoplastic polymer melting.
Abstract:
A flotation device for floating a watercraft is provided. The flotation device comprises a cover releasably secured to the watercraft. A first collapsible tubing is positioned between the cover and the watercraft for removing at least a portion of the cover. At least one inflatable flotation bladder is positioned between the cover and the watercraft wherein upon inflation of the first collapsible tubing, the first collapsible tubing releases at least a portion of the cover from the watercraft.
Abstract:
Systems and methods are provided for managing health of electrolytes of redox flow battery system. Components of the system may include a redox rebalancing cells and a gas storage system. The redox rebalancing cell may be operated by plating iron on a plating electrode, treating a negative electrolyte of the redox flow battery system with the plated iron and returning the negative electrolyte to an electrolyte tank. The gas storage system may include a set of expandable gas storage tanks coupled to at least one electrolyte storage tank and an electrolyte rebalancing system of the redox flow battery system.
Abstract:
Embodiments of systems and methods for transporting fuel and carbon dioxide (CO2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO2. Insulation may provide temperature regulation for the fuel and CO2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO2.
Abstract:
A pressurized gas storage system is disclosed for maintaining a minimum pressure of a primary fluid (5). The system includes a pressurized gas tank (2) inside which is mounted a flexible bladder (4) which contains the primary fluid. The space between the gas tank and the bladder is considered a compression chamber (9) which contains a secondary fluid (7) that exerts pressure on the bladder to maintain a minimum pressure upon the primary fluid. The secondary fluid is supplied to and exits tank pressure chamber through a port (6). The flexible bladder is couple to inlet outlet port (8) extending to a pickup tube (10). The system also includes a pump (18), fluid reservoir (14), pressure relief valve (24) and controller (26) which functions to maintain the pressure of the secondary fluid. In a second embodiment, pressure is maintained through a second fluid absorbing and releasing material.
Abstract:
A liquid storage tank comprising an outer container wherein the outer container is rigid and has at least one inner container disposed within the outer container. The at least one inner container contains at least one stored liquid which may be refilled from a surface vessel or host facility. The at least one inner container is flexible and pressure balanced while the volume of the outer container remains fixed, and the volume of the at least one inner containers is variable. Disposed on the outer container is a balance assembly containing an isolation valve, a check valve, and a flexible bladder. The balance assembly allows for the hydrostatic pressure to be maintained during chemical dosing and tank raising operations.
