Abstract: A dosing vessel includes a reservoir having an inlet and an outlet and is configured to contain a supply of a cryogenic liquid with a headspace above. The outlet is configured to be connected to a dosing arm having a dosing head. A low pressure sensor is configured to detect a vapor pressure in the headspace. A high pressure sensor is configured to detect a pressure in a bottom portion of the reservoir. An inlet valve is in fluid communication with the inlet of the reservoir and is placed in communication with a source of cryogenic liquid. A controller is in communication with the high and low pressure sensors and the inlet valve and is configured to store a preset liquid level or a preset differential pressure corresponding to the preset liquid level, to determine a measured differential pressure based on data from the high and low pressure sensors and to control the inlet valve based on the measured differential pressure and the preset liquid level or the preset differential pressure so that a liquid level of a cryogenic liquid stored in the reservoir is generally maintained at the preset liquid level.

Abstract: A doser for dispensing a cryogenic fluid includes a doser body configured to receive the cryogenic fluid. A dosing arm has a proximal end and a distal end, with a central passage extending between the proximal and distal ends and configured to receive cryogenic fluid from the doser body. Multiple dosing heads are mounted to the distal end of the dosing arm with each of the dosing heads including a dosing valve. The dosing heads are configured to receive cryogenic fluid from the central passage of the dosing arm and to dispense the cryogenic fluid when the dosing valve is opened.

Abstract: A nozzle includes a nozzle bayonet with a warm seal positioned at a distal end and a nose seal positioned at a proximal end so that a distal passage is defined between the warm and nose seals. The nozzle also includes a nozzle poppet valve. Purge and vent lines are in fluid communication with the distal passage. A receptacle includes a receptacle poppet valve, a receptacle inner tube and a receptacle outer tube with a receptacle insulation space defined therebetween. A coupling space is defined between an outer casing and the receptacle outer tube. The receptacle coupling space receives the nozzle bayonet. The receptacle sequentially engages the warm seal and the nose seal of the nozzle during insertion of the nozzle bayonet into the receptacle coupling space with the nozzle and receptacle poppets engaging to open the nozzle and receptacle poppet valves when the nozzle bayonet is fully inserted into the receptacle coupling space.

Abstract: A storage tank system features a tank made of rigid material and an insulation assembly. The insulation assembly includes an inner membrane and an outer membrane wherein the inner membrane is located within the outer membrane and at least one of the inner membrane and outer membrane is made of a flexible material. An insulation medium is located in a space between the inner membrane and the outer membrane and a vacuum is applied to the space.

Abstract: A body structure has an inlet port that receives fluid, a first outlet port that connects to a top-fill line of a cryogenic tank, a second outlet port that connects to a bottom-fill line of a cryogenic tank and a slider tube cylinder. A cylinder housing connects to the body structure and has a pressure comparison cylinder with upper and lower volumes, with the latter in fluid communication with a cryogenic tank. A piston having a piston shaft slides within the pressure comparison cylinder. A pressure regulator is in fluid communication with the upper volume and the slider tube cylinder. A slider tube is connected to the piston shaft and slides within the slider tube cylinder. The slider tube cylinder selectively directs fluid to a top-fill line through the first outlet port or to a bottom-fill line through the second outlet port.

Abstract: A system for dispensing a cryogenic fluid includes a bulk storage tank configured to contain a supply of the cryogenic fluid. A heat exchanger coil is positioned in the headspace of at least one intermediate fluid tank, which contains an intermediate fluid, and is configured to receive and warm a cryogenic fluid from the bulk storage tank via heat exchange with intermediate fluid vapor in the headspace. A buffer tank receives fluid from the heat exchanger coil. A chiller coil is positioned within the intermediate fluid tank and is submerged within intermediate fluid liquid contained within the at least one intermediate fluid tank. The chiller coil receives fluid from the buffer tank and cools it via heat exchange with intermediate fluid liquid within which the chiller coil is submerged for dispensing.

Abstract: A system for cryogenic gas delivery includes a cryogenic tank configured to contain a cryogenic liquid and a gas within a headspace above the cryogenic liquid. The system also includes first and second vaporizers and a use outlet. A first pipe is configured to transfer gas from the headspace through the first vaporizer to the use outlet. A second pipe is configured to transfer liquid from the tank through the first vaporizer so that a first vapor stream is directed to the use outlet. A third pipe is configured to build pressure within the tank by transferring liquid from the tank through the second vaporizer so that a second vapor stream is directed back to the headspace of the tank. A first regulator valve is in fluid communication with the second pipe and opens when a pressure on an outlet side of the first regulator drops below a first predetermined pressure level. A second regulator valve is in fluid communication with the third pipe and opens when a pressure inside the tank drops below a second predetermined pressure level. The first predetermined pressure level is higher than the second predetermined pressure level.
