Abstract
A cryogenic fluid delivery manifold system includes a plurality of cryogenic supply tanks. A liquid flow manifold permits flow of liquid a use device. A vapor pressure manifold is coupled to the supply tanks and to a pusher tank for regulating and/or balancing pressure across the plurality of supply tanks.
Claims9
A cryogenic fluid supply system, comprising:
- a plurality of cryogenic supply tanks, wherein each tank includes:
- a. a cryogenic liquid and a vapor above the liquid;
- b. a vapor line having a first end in fluid communication with the vapor of the tank;
- c. a liquid line having a first end in fluid communication with the liquid of the tank;
- a pusher tank that acts to supply vapor pressure to the supply tanks and that contains a cryogenic liquid and a vapor above the liquid, the pusher tank including a dedicated pressure building system formed of a pressure line that communicates on one end with the liquid of the pusher tank, and on another end with the vapor of the pusher tank, the pressure building system also including a first vaporizer positioned along the pressure line to vaporize liquid from the pusher tank and direct the vaporized liquid back to the vapor in the pusher tank for pressurizing the pusher tank;
- a vapor manifold that fluidly couples the vapor lines of the supply tanks to one another and also fluidly couples vapor lines of the supply tanks to a pusher line that communicates with the liquid of the pusher tank, the pusher line including a pusher vaporizer that vaporizes liquid from the pusher tank;
- a liquid manifold that fluidly couples the liquid lines of the supply tanks to one another, wherein the liquid manifold communicates with a use line that is configured to be connected to a use device.
