Described is a cylinder (1) for high pressure compressed fluids comprising a first hollow body (2) having an opening (2a) towards the outside (100) forming with the relative internal cavity a first housing space (2b) for a compressed fluid; at least one second hollow body (3) having an opening (3a) towards the outside (100) and forming with the relative internal cavity a second housing space (3b) for a compressed fluid which is separate and different from the first housing space (2b). The second hollow body (3) is housed inside the first hollow body (2) in such a way as to define a first housing chamber (6) and a second housing chamber (7). The first and second chambers (6, 7) have, respectively, an opening (2a, 3a) towards the outside (100) at the head end (4) of the cylinder (1) and at least the first or the second hollow body (2, 3) has at a bottom end (5) a bottom opening (“C”) which is normally closed.

A heat-insulating container being used under an environment where exposure to water of liquid is possible, includes a container main body having a substance holding portion which holds a substance at a temperature which is lower than a normal temperature on the inside of the substance holding portion; and a heat-insulating structure body which is provided in the container main body and includes at least a vacuum heat-insulating material. In addition, the vacuum heat-insulating material includes an outer cover material and an inner member sealed in a tightly closed and decompressed state on an inside of the outer cover material. In addition, the inner member is configured of a material which does not generate hydrogen in a case of coming into contact with the moisture of the liquid.

An LN storage tank is disclosed. The LNG storage tank includes: a lower insulation board for insulating LNG from the outside; a heating member placed on the lower insulation board; a main secondary barrier attached on the heating member; an upper insulation board attached on part of the main secondary barrier; and an auxiliary secondary barrier attached on the other part of the main secondary barrier, wherein a first adhesive layer may be interposed between the main secondary barrier and the auxiliary secondary barrier.

A cryogenic tank assembly includes a cryogenic tank having an internal volume that is configured to contain liquefied natural gas (LNG). The cryogenic tank includes an inlet and an outlet that are each fluidly connected to the internal volume. The assembly includes a recirculation conduit coupled in fluid communication between the inlet and the outlet. The recirculation conduit extends along a path between the inlet and outlet external to the internal volume of the cryogenic tank such that the path is configured to be exposed to an ambient environment of the cryogenic tank. The recirculation conduit is configured to: receive a flow of LNG from the internal volume through the outlet; transfer heat from the ambient environment to the LNG flow to change the LNG flow to a flow of natural gas; and inject the natural gas flow into the internal volume of the cryogenic tank through the inlet.

A portable cryogenic container includes a porous material configured to absorb a cryogenic coolant such as liquid nitrogen. The coolant-absorbing material at least partially defines a storage cavity in the container that is configured to accept and support a cassette or other type of contents container in which a product to be cryogenically stored is contained. With cryogenic coolant absorbed into the container, the temperature within the storage cavity can be maintained sufficiently close to the boiling point of the cryogenic coolant to preserve post-thaw viability of the stored product for several hours.

This invention relates to methods and systems for reliable ultra-high purity (UHP) helium gas supply and maintaining dedicated onsite inventory. Specifically, the invention employs multiple ISO containers whereby vaporized UHP helium in the standby ISO container(s) is used to build-up pressure in the online ISO container. The thermal shields of the ISO containers can be used to decrease heat leaks into the backup ISO container thereby decreasing helium vaporation rate and the amount of gas needed to be withdrawn in order to maintain the maximum allowable working pressure (MAWP) of the vessel. An even lower supply rate is possible by drawing UHP helium gas using an economizer valve but maintaining liquid in the ISO container. This makes it possible to efficiently manage the supply rate, from low flows to higher flow requirements, and to optimize UHP helium draw rate from the storage vessels. A further advantage is that UHP helium gas sent to the customer is of higher purity since it comes directly from a liquid source. The UHP helium gas can be used in semiconductor manufacturing, e.g., as a carrier gas to introduce precursors into deposition chambers during thin film deposition on the wafers.
