A recovery cryostat, external to a cryogen storage tank, uses a cryocooler to condense vapor of cryogen from the storage tank and return the cryogen to the storage tank as a liquid. The process may be continuous or cyclical depending on the orientation of the recovery cryostat. If the recovery cryostat is located such that liquid can drain back to the storage tank, the process can be continuous. If the liquid cannot be drained back, a valve on the liquid return line is closed while the cryocooler condenses the vapor, a valve on the vapor supply line is then closed, the valve on the liquid return line is opened, and pressure in the recovery cryostat is increased to drive the liquid out. The storage tank is a type that can have vapor that boils off external to the tank be returned to the vapor space above the liquid in the tank.

Container systems for the transportation and/or storage of Liquefied Natural Gas (LNG) are provided. The container systems include: a) an outer shell; b) an inner pressurized container, wherein the inner pressurized container comprises a first chamber having a first vent and at least one other chamber having a second vent; c) at least one heat exchange zone in thermal communication between the first chamber and the at least one other chamber; and d) an interstitial space between the outer shell and the inner pressurized container including at least a partial vacuum. Methods for transporting and/or storing LNG using the aforementioned container systems are also provided.

A method and system for forming a compressed gas and dispensing it to a compressed gas receiver. The compressed gas is formed from a process fluid provided at a cryogenic temperature. The forming includes pressurizing the process fluid, feeding the pressurized process fluid at still a cryogenic temperature to a heat exchanger and heating it in indirect heat exchange with a thermal fluid which is provided in a reservoir at a thermal fluid temperature above the cryogenic temperature of the pressurized process fluid. Once heated to a suitable temperature the compressed gas may be dispensed to the compressed gas receiver or stored in one or more compressed gas storage vessels for later use.

The invention relates to a gas container equipped with a gas distribution valve having an electronic device for measuring gas autonomy. Flow selection means allow a desired gas flow to be selected. The electronic device includes a pressure sensor. Signal processing means allow gas autonomies to be determined on the basis of the pressure signal and of the selectable gas flows. A selection component cooperates with the signal processing means in order to successively display, on data display means and in response to successive digital activations by the user of the selection component, the various selectable flow values and the various corresponding autonomies, with each flow value being simultaneously displayed with a corresponding autonomy.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

A sensor mounting assembly is configured for use with a vessel arrangement including at least four vessels. The assembly includes first and second elongated frame members, first and second rollers, and first and second sensors. The first sensor is attached to the first elongated frame member and is configured to contact the surface of the first vessel upon actuation in a first direction. The second sensor is attached to the second elongated frame member and is configured to contact the surface of the second vessel upon actuation in a second direction that is substantially orthogonal to the first direction. This disclosure also describes a method of mounting at least six sensors for use with a vessel arrangement including at least four vessels, the vessel arrangement disposed in a container in a two-by-two stacked configuration having a central space.

A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit including a collection of valve shutter(s) comprising at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve including a mechanism for manually controlling the collection of valve shutter(s), the control mechanism being mounted with the ability to move on the body between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control mechanism actuates the collection of valve shutter(s) into a position in which the circuit is open to a first bore section.

A valve for pressurized fluid, including a body having a front face and a rear face and housing an internal fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit including a collection of valve shutter(s) including at least one shutoff valve shutter for closing or opening the circuit, the valve comprising a member for manually controlling the collection of valve shutter(s).

The invention relates to a pressurized gas container, in particular a gas cylinder, having an internal volume for gas storage, a fluid-distributing valve, a pressure sensor and microprocessor-based control means. The microprocessor-based control means are configured to detect filling of the gas container with gas, by comparing said at least one pressure value measured by the pressure sensor with at least one predefined and stored reference pressure threshold value; then to initiate a timer on the basis of a detection of filling of the gas container with gas; and to trigger a warning when the timer exceeds a given period calculated from the initiation of the timer.

An energy utilization system can initially store a plurality of different fuels in a fuel storage pod before choosing a fuel ratio with a blend module connected to the fuel storage pod. The fuel ratio chosen in response to an electrical generation parameter tracked by the blend module. The supply of at least two of the plurality of different fuels to a power generator with the chosen fuel ratio allows for the combustion of the supplied fuels with the electrical power generator to create electricity.
