Abstract:
A liquefied natural gas (LNG) re-gasification unit wherein a buoy can be floated in the water for engaging a floating vessel for transport of LNG and a storage vessel can have a deep water gas storage system for storing a compressed gas. A inflexible thin single walled vessel can be for storing compressed gas under water in deep water, wherein the storage vessel is pressure equalized by water surrounding the inflexible thin single walled vessel. A compressed gas intake can be for admitting and discharging compressed gas to and from the inflexible thin single walled vessel. A water port can be for admitting and discharging water to the inflexible thin walled storage vessel and a valve disposed at the compressed gas intake to the inflexible thin single walled vessel for controlling compressed gas admission and discharge to the vessel.
Abstract:
An apparatus for compressing a gas and its uses are disclosed. The apparatus comprises a fixed-volume container having a hollow and a moveable element subdividing said hollow into a first variable-volume portion and a second variable-volume portion, the second variable-volume portion having an opening for introducing therein a hydraulic and/or pneumatic fluid under pressure, for causing an increase in the volume of said second variable-portion by moving said moveable element, thereby, consequently, decreasing the volume of the first variable-volume portion and compressing a gas contained therein.
Abstract:
Liquefied natural gas is stored under water in a submerged, jacketed container the interior of which is coupled to a balancing fluid in another container, the balancing fluid being in turn coupled to the water surrounding both containers. The containers are fastened together, and the assembly is ballasted as appropriate, or required.
Abstract:
Disclosed are a hydrogen tank and a method of operating the same. The hydrogen tank includes a tank vessel configured with an enclosed interior space for storing an admixture of carbon dioxide and gaseous hydrogen; and a tank port configured to fluidly contact the interior space of the tank vessel and including a semipermeable membrane, which is configured substantially permeable for the gaseous hydrogen and substantially impermeable for the carbon dioxide and is arranged to seal the tank vessel against the outside. The gaseous hydrogen can enter and leave the tank vessel through the tank port via the semipermeable membrane but carbon dioxide is kept in the tank vessel.
Abstract:
A storage device for storing a gas, in particular for storing gaseous hydrogen, having a first chamber for receiving the gas and a locking device for closing and opening a flow path connected to the first chamber. The storage device further has an adjustment unit for volume change of the first chamber. Further there is disclosed a gas storage unit which is the storage device wherein the gas is stored in the first chamber and to a method for the at least partial filling or emptying of the gas storage unit.
Abstract:
A pressure tank includes a metallic vessel, a plastic liner received in the metallic vessel, a flexible diaphragm, two connectors and a nozzle coupled to the nipples respectively. The metallic vessel includes upper and lower shells. The upper shell defines a first planar area on a side thereof and a second planar area on a top thereof. The lower shell defines a third planar area therebottom. The flexible diaphragm divides the metallic vessel into a storage space and a pneumatic room. Each of the connectors includes a nipple and an anti-leak assembly. The nipples of the connectors are mounted on the side and top of the upper shell respectively and are in communication with the storage space. The two anti-leak assemblies provide leakproof connection between the nipples and the plastic liner. Additionally, the nozzle is mounted on the third planar area to be in communication with the pneumatic room.

Abstract:
A tank especially suitable for use as a fuel or oxidizer tank in spacecraft is divided into two tank spaces by a membrane. A liquid is stored on one side of the membrane and a pressure gas is stored on the other side of the membrane. The pressure gas is to drive the liquid out of the tank. The membrane is made of a polymer material and is held by a spring ring in a recess on the outer wall of the tank. The spring ring has a substantially C-shaped cross-section to exert elastic spring holding forces on the membrane in the recess.
Abstract:
A pressure vessel includes: an outer container unit having an inner space and first and second supporting portions; a lining container disposed inside the outer container unit and having an end portion that corresponds to the first supporting portion; an elastic diaphragm disposed in and dividing the inner space into air and water chambers, and having retaining and extending sectors that correspond in position to the end portion and the second supporting portion respectively; and a pressing member disposed in the air chamber and having first and second pressing segments that press tightly the retaining sector and the end portion against the first supporting portion and the extending sector on the second supporting portion respectively.
Abstract:
Disclosed is a valve assembly for a fluid dispenser including a valve body and a valve stem slidably located in the valve body. The valve stem has at least one exit hole located at a tip of the valve stem. A valve stem adapter is located at the tip of the valve stem and affixed thereto. The valve stem adapter includes at least one adapter exit hole to allow exit of a dispensible fluid from the valve assembly. Further disclosed is a dispenser for a fluid including a cannister, an inner bag for dispensible fluid located inside of the cannister, and a valve assembly including a valve stem adapter is located at a tip of a valve stem and affixed thereto. The valve stem adapter includes at least one adapter exit hole to allow exit of a dispensible fluid from the valve assembly.
