The present invention relates to a cryogenic vessel (300a, 300b) having an inner container (301), an outer container (302), an intermediate space (303) between the inner container (301) and the outer container (302) which can be evacuated, and having at least one fluid distribution container (200), which has an internal volume which extends proceeding from one wall of the inner container (301) into the intermediate space (303), is arranged at least partially within the intermediate space (303) and is fluidically connected to the inner container (301), wherein the internal volume of the fluid distribution container (200) is delimited by a wall which has openings (211, 212, 213) that are designed for the connection of one line (311, 312, 313) each or are each connected with one such line (311, 312, 313). The wall (121, 221) has a convex section (101, 201), wherein a wall thickness of the wall at at least one point is less than 90% of a wall thickness of the inner container (301). The invention also relates to a fluid distribution container (100, 200) and to a method for producing a cryogenic vessel (300a, 300b).

A system and method for supplying a backup product in an air separation device, as well as a system and method for supplying a lower-pressure product to a user by means of pressurization of a cryogenic liquid pump during normal operation of an air separation device, i.e., when the cryogenic liquid pump is in the cold standby state. By means of the system and method, a cryogenic liquid product taken from a storage tank is pressurized by the cryogenic liquid pump to produce a lower-pressure product by taking full advantage of the low-speed operation of the cryogenic liquid pump in the cold standby state, and the lower-pressure product is transmitted to product supply lines of a user, to achieve the function of supplying the lower-pressure product to the user. The system and method not only reduce the energy loss of the cryogenic liquid pump in the cold standby state for a long time, but also avoid the bleeding rate of the cryogenic liquid product generated by sending a part of the cryogenic liquid product back to the storage tank, so that the advantage of quickly starting the cryogenic liquid pump from the cold standby state is ensured, and the requirements of the user to the higher-pressure product and the lower-pressure product can be satisfied.

The invention relates to a liquefied-fluid storage tank including a storage wall the inner surface of which defines a storage volume for liquefied fluid, the tank including an exchanger for cooling the fluid contained in the tank in particular to condense vapors of said fluid. The invention is characterized in that the cooling exchanger includes a body of metal, in particular aluminum, in which at least one pipe of a coolant circuit is integrated in order to cool said body and in that the body is in contact with and attached to the outer surface of the storage wall.

A gas displacement assembly includes a storage container, a pump that pumps a pressurized gas material into the storage container, a cooling chamber that houses a coolant and cools the gas material to a cryogenic temperature, and a coolant line that transports coolant through the cooling chamber to cool the gas material.

An arrangement comprising at least one liquefaction plant for liquefying a gaseous medium to produce a liquefied medium; and at least one storage tank for storing the liquefied medium. A first transfer line is provided which is connected between the liquefaction plant and the storage tank, for transferring liquefied medium from the liquefaction plant into the storage tank. A second transfer line is connected between the liquefaction plant and the storage tank, for transferring gaseous medium from the storage tank into the liquefaction plant. The second transfer line, which used for transferring medium from the storage tank into the liquefaction plant, is arranged so that it is routed at least partially through the area of the storage tank in which the liquefied medium is stored in use.

A compressed gas energy storage system may include an accumulator for containing a layer of compressed gas atop a layer of liquid. A gas conduit may have an upper end in communication with a gas compressor/expander subsystem and a lower end in communication with accumulator interior for conveying compressed gas into the compressed gas layer of the accumulator when in use. A shaft may have an interior for containing a quantity of a liquid and may be fluidly connectable to a liquid source/sink via a liquid supply conduit. A partition may cover may separate the accumulator interior from the shaft interior. An internal accumulator force may act on the inner surface of the partition and the liquid within the shaft may exert an external counter force on the outer surface of the partition, whereby a net force acting on the partition is less than the accumulator force.

A system to convert and dispense pressurized gas(es) of cryogenic liquids of gas(es), and systems and methods to efficiently convert liquid natural gas (LNG) to compressed natural gas (CNG) and low pressure natural gas (NG) and other cryogenic liquids of gas. The system requires one dedicated pressure vessel of horizontal and vertical elements at the dispensing location to convert, retain, store, and dispense multiple pressures of gas from a cryogenic liquid supply such as a non-dedicated high pressure cryogenic personal supply tank. The system efficiently modifies and controls parameters of volume, pressure, and temperature in conversion scale to retain all converted product under human control to dispense without process required waste for use in commercial, industrial, and in particular single family residential applications and service can be accomplished by pickup truck and trailer, where semi trucks, big rig trucks and process pollution are not welcome.

The invention relates to a tank container (100; 100) for the transport and storage of cryogenic liquefied gas, comprising a framework (120) and a cylindrical vessel (110) connected to the frames work (120), wherein the vessel (110) is covered by a superinsulation arrangement (130) based on an aerogel composition, and the vessel (110) is connected to the framework (120) by a clamping device (30) which is adapted to allow for a relative movement between the framework (120) and the vessel (110) due to thermal expansion or contraction of the vessel (110).

A method for replenishing the supply of cryogenic liquid from a storage tank (2) includes: pressurizing a container (14) with cryogenic gas at a first pressure, said container having passing through it a first cryogenic fluid flow line referred to as the cold line and a second cryogenic fluid flow line referred to as the hot line, passing cryogenic liquid at a second pressure through the cold line (12), and supplying the container (14) with cryogenic gas at least partially from cryogenic liquid pumped from the storage tank (2) and vaporized. A device is also provided for the method hereinabove.
