  • Publication number: 20220128195
    Abstract: A method and system for forming a compressed gas and dispensing it to a compressed gas receiver. The compressed gas is formed from a process fluid provided at a cryogenic temperature. The forming includes pressurizing the process fluid, feeding the pressurized process fluid at still a cryogenic temperature to a heat exchanger and heating it in indirect heat exchange with a thermal fluid which is provided in a reservoir at a thermal fluid temperature above the cryogenic temperature of the pressurized process fluid. Once heated to a suitable temperature the compressed gas may be dispensed to the compressed gas receiver or stored in one or more compressed gas storage vessels for later use.

  • Patent number: 11287089
    Abstract: The invention relates to a process for fueling of vehicle tanks with compressed hydrogen comprising splitting ammonia into hydrogen and nitrogen in an ammonia cracking unit, compressing the hydrogen from the ammonia cracking unit, and dispensing the compressed hydrogen to the vehicle tanks in a hydrogen fueling unit comprising one or more dispensing units, wherein chilled ammonia is used to cool the compressed hydrogen before being dispensed to the vehicle tanks by heat exchange between the compressed hydrogen and the chilled ammonia so that the chilled ammonia is heated, and transferring the heated ammonia to the ammonia cracking unit.

  • Patent number: 11167732
    Abstract: A system comprising an ammonia cracking unit in which ammonia is split into hydrogen and nitrogen and a hydrogen fueling station for fueling of vehicle tanks with hydrogen from the ammonia cracking unit which comprises gas operated valves (GOVs), one or more hydrogen compressing units wherein the hydrogen from the ammonia cracking unit is compressed, and one or more dispensing units for dispensing the compressed hydrogen to vehicle tanks which each comprise a nozzle through which the hydrogen is passed to the vehicle tank, wherein nitrogen from the ammonia cracking unit is used in e.g.: the operation of one or more of the GOVs; for blanketing one or more of said hydrogen compressing units; for blanketing and/or purging one or more of the dispensing units; for drying one or more of the nozzles between uses to prevent nozzle freeze on.

  • Patent number: 5517827
    Abstract: The present invention is a tunnel freezer which incorporates a "dual flow" design whereby the refrigerant is introduced at each end of the tunnel and withdrawn from the middle of the tunnel. A key to the present invention is that the dual flow design allows one to confine the pressure gradient for leaks between the ends of the tunnel where it will not be a concern since the item entrance and exit ports (which ports provide a ready access for leaks) are located at the ends of the tunnel.

  • Patent number: 5509277
    Abstract: The present invention is a combination immersion/impingement tunnel freezer. A solid conveyor belt moves the items to be frozen through an initial immersion section wherein the conveyor belt is immersed in a bath of liquid refrigerant. Subsequently, the conveyor belt moves the items to be frozen through an impingement section wherein the evaporated refrigerant from the immersion section is directed toward the solid conveyor belt at a high velocity and at an angle substantially perpendicular to the longitudinal axis of the tunnel.
