Liquid cryogen delivery and injection control apparatus
A delivery apparatus and method for delivering liquid cryogen to a chilling application includes a liquid cryogen feed tank; a liquid cryogen conduit in fluid communication between the feed tank and the application, wherein the feed tank is in fluid communication with a vessel which is in fluid communication with the conduit between the feed tank and the application; a weight measurement device for controlling the weight of liquid cryogen to be delivered to the application through the conduit; a flow controller for controlling the speed of delivery of the liquid cryogen to the application; wherein the application utilizes the liquid cryogen and produces an exhaust gas; a device for measuring the temperature of the exhaust gas, the device in operative communication with the flow controller; wherein the flow controller is configured to vary the speed of delivery of liquid cryogen from the vessel through the conduit in response to the temperature of the exhaust gas.
Dual stirling cycle liquid air battery
The invention relates to a liquid air energy storage system. The storage system includes a cryocooler, a dewar, and a Sterling engine. The cryocooler cools a tip of a cold head to cryogenic temperatures, the cryocooler further includes a heat sink to reject heat from the cryocooler and a cold head that protrudes into a dewar through a cryocooler cavity, the cold head to condense ambient air to create liquified air in the dewar. The dewar holds the liquified air at low temperatures, the dewar having the cryocooler cavity and a Stirling cavity. The Stirling engine drives an electric generator, the Stirling engine further including a cold finger protruding into the dewar through the Stirling cavity, the cold finger to move the liquified air from the dewar to a Stirling heat sink; the Stirling heat sink to expand the liquified air; and the electric generator to generate output electricity.
Thermally-insulating sealed tank
The invention relates to a tank wall (1) fixed onto a supporting wall (3) wherein the secondary insulating barrier comprises a plurality of secondary rows (A, B, C) parallel to a first direction and juxtaposed in a second direction at right angles to the first direction according to a repeated pattern. The secondary sealed membrane comprises a plurality of strakes (21) parallel to the first direction, the size of the repeated pattern of the secondary rows (A, B, C) being an integer multiple of the size of a strake (21) in the second direction. The primary insulating barrier (5) comprises a plurality of primary rows parallel to the first direction, and the primary sealed membrane has first corrugations (56) parallel to the first direction and spaced apart by a first regular spacing (58), wherein the size of the repeated pattern of the primary rows is an integer multiple of said first regular spacing (58).
Motor vehicle having a pressure vessel, and operating method for a motor vehicle
A motor vehicle with a pressure vessel system includes at least a first pressure vessel arranged in a first region of the motor vehicle and at least one second pressure vessel arranged in a second region of the motor vehicle having a lower intrusion probability than the first region. Fuel is preferentially removed first primarily from the at least one first pressure vessel. When the lower limit of fuel level or fuel temperature is reached in the at least one first pressure vessel, fuel is removed from the at least one second pressure vessel. If the fuel supply rate from the at least one first pressure vessel is lower than an overall fuel supply rate for an energy converter, fuel is removed from the at least one second pressure vessel to meet the overall fuel supply rate needed by the energy converter.
Cryogenic trench/trough apparatus and method
A method of installing a trench for containing a cryogenic spill, including the step of constructing multiple precast concrete sections at a first location, each section preferably having a bottom wall and spaced apart side walls connected to and extending up from the bottom wall. Each section preferably has end portions that enable connection to another said concrete section. The method includes applying a polymeric concrete material to the bottom wall and side walls of each concrete section preferably using a spray application. The concrete sections are connected together using connections that preferably join one end portion of a concrete section to and end portion of another concrete section. An epoxy grout or non-sag seal can be preferably applied to the connections.
SYSTEM AND METHOD FOR VAPORISING LIQUIFIED NATURAL GAS FOR MEASUREMENT THEREOF
A method of vaporising liquefied natural gas (LNG) for measurement of its constituent components may include receiving LNG from a main pipeline into a pressurising device. The method may also include via the pressurising device, pressurising a the LNG beyond a critical pressure thereof. The method may further include directing a first portion of the pressurised LNG to a heater. The method may still further include via the heater, heating the first portion of pressurised LNG beyond a critical temperature thereof, and directing the pressurised and heated LNG to a vaporising device. The method may also include via the vaporising device, depressurising the heated LNG to a pressure below the critical pressure so as to vaporise the LNG.
TANK AND METHOD OF MANUFACTURING THE SAME
A tank includes a liner that includes a barrel portion in a cylindrical shape and a pair of dome portions provided at both ends of the barrel portion in the axial direction, and a reinforcing layer that covers the liner and that is formed from a fiber reinforced resin formed by impregnating a fiber bundle with a resin. A portion of the reinforcing layer that covers the dome portions includes a radial arrangement layer in which fibers of the fiber bundle are arranged radially along the radial direction of the dome portions when seen in the direction of an axis of the tank.
METHOD AND SYSTEM FOR CONTAINING A SMALL ATOMIC STRUCTURE GAS
In a hydrogen or helium container and method for containing the gas, a double-walled housing is provided, which defines an inter-space between the inner and the outer walls, the inter-space being filled with a fluid at a higher pressure than the pressure of the hydrogen or helium contained within the inner wall.
STORAGE TANK FOR LIQUID HYDROGEN
A storage tank for liquid hydrogen comprises first and second shells each constructed of laminate material, the second shell being disposed outwardly of the first shell with respect to the centre of the storage tank. The first and second shells are mechanically connected by a first plurality of pins each of which passes through at least some layers of the second shell and at least some layers of the first shell. The storage tank may be constructed using a simpler manufacturing process involving less tooling and fewer process steps than is the case for known tanks for storing liquid hydrogen. The storage tank has also has a lower mass and reduced thermal losses compared to tanks of the prior art. The plurality of pins allows for the shells to be thinner, and hence lighter, than similar shells in tanks of the prior art.
DEVICE FOR STORING AND TRANSPORTING LIQUEFIED GAS
A device for storing and transporting liquefied gas, including a first inner reservoir extending in a longitudinal direction, a second outer reservoir, the device having a system for holding the first reservoir in the second reservoir having a first rigid connection between the first reservoir) and the second reservoir at a first longitudinal end, and, at a second longitudinal end of the device, a mechanism for suspending the first reservoir inside the second reservoir having an assembly of tie rods, a first end of the tie rods being attached to a sheath that is secured to the first reservoir via a washer(s) and nut assembly, these being fitted around the tie rod, a second end of the tie rods being attached to a sheath that is secured to the second reservoir via a washer(s) and nut assembly.
