A hydrogen refueling station evaluation device includes a socket that is supplied with hydrogen, a hydrogen tank that stores the hydrogen supplied through the socket, and a discharge pipeline that discharges hydrogen from the hydrogen tank to the atmosphere. A discharge valve adjusts open and closed states of the discharge pipeline. A tank protection valve achieves a state in which the socket and the hydrogen tank are connected to each other, a state in which the socket and the discharge pipeline are connected to each other and the hydrogen tank is closed, and a state in which all of the socket, the hydrogen tank, and the discharge pipe are connected to one another. A gas supplier supplies an inert gas to the socket and a controller operates the tank protection valve, the discharge valve, and the gas supplier.

The liquid nitrogen conveying pipeline includes a first pipeline and a second pipeline. The first pipeline connects the lower part of the liquid nitrogen storage tank, the gasification device, and the upper part of the liquid nitrogen storage tank sequentially in that order. The second pipeline connects the liquid nitrogen storage tank, an input end of the liquid nitrogen spray gun, and a first input end of the mixed spray gun. The mixed spray gun includes a first input end, a second input end, a liquid nitrogen nozzle, and a spray pipe. The spray pipe includes a contraction section, an expansion section, and an acceleration section.

Device for storing and supplying fluid fuel, comprising a tank for liquefied fuel gas balanced with a gaseous phase, in particular a hydrogen gaseous phase, a circuit for filling the tank, at least one circuit for extracting fluid from the tank, at least one circuit for controlling the pressure in the tank, the circuits for filling, extracting and controlling the pressure comprising a valve assembly arranged in a housing which is separate from the tank, the housing being detachably connected to the tank via a removable mechanical coupling system, the extraction circuit, the pressure control circuit and the filling circuit comprising an assembly of removable fluid connections which are located at the junction between the tank and the housing and configured to enable separation between the portions of circuits located in the tank and in the housing when removing the housing from the tank.

Provided is a valve for high-pressure gas, wherein a sheet member is provided inside a through hole formed in a valve body of the valve, wherein the sheet member constitutes a channel for high-pressure gas inside the through hole, wherein the sheet member is fixed inside the through hole by a pressing member, wherein an end opening of the through hole is closed by a lid member, wherein a gasket is provided at a peripheral part of the end opening of the through hole, wherein the gasket is sandwiched between the lid member and the valve body, wherein the lid member is pressed toward the valve body by a plug, and wherein a bearing is provided between the plug and the lid member.

Pressurized gas tanks are filled from at least one gas source using a transfer circuit, a set of buffer storage tanks and at least one compressor. The set of buffer storage tanks may be filled with pressurized gas from the at least one gas source by pressure balancing via balancing lines without going through the at least one compressor. The set of buffer storage tanks may also be filled with pressurized gas from the at least one gas source that is compressed by the at least one compressor.

This invention relates to a method and system for improved gas delivery for regulating gas at a substantially constant delivery pressure on a consistent basis. The system includes an automated redundant pressure regulation safety feature that is specifically configured along a flow network to significantly reduce the occurrence of pressure surges due to failure of the gas to be regulated to the delivery pressure. By reducing the occurrence of pressure surges and utilizing higher pressure package gas sources, the frequency of changeouts can be lowered.

The gas supply system of this invention is furnished with a cylinder apparatus having a pneumatic valve that supplies process gas to a process chamber, and a solenoid valve that opens or closes said pneumatic valve by supplying or stopping the flow of valve actuating gas to said pneumatic valve; and a gas supply control apparatus that controls the actuation of the solenoid valve. In addition, said gas supply control apparatus comprises a main controller that controls the actuation of said solenoid valve during normal operation, and a sub-controller that senses an abnormal state of said main controller and if an abnormality is sensed, controls the actuation of said solenoid valve instead of said main controller.

A fluid cargo handling system with a standoff system includes a floating marine platform having an elongated first platform side, an elongated second platform side and a buoyant hull with a hull bottom. A fluid cargo transfer hose is carried on a hose reel mounted on the platform. A drive system maintains the marine platform at an offset distance from another marine platform, preventing physical contact therebetween. The drive system has at least two drive devices adjacent the first platform side and at least two drive devices adjacent the second platform side, with each of the drive devices along the first side engaging a separate driveline extending from the hull bottom adjacent the first side towards the second platform side and each of the drive devices along the second side engaging a separate driveline extending from the hull bottom adjacent the second side towards the first platform side.
