ABSTRACT:
Gas is vented from a non-cryogenic liquid storage tank 12 while discharging pressurized liquid from a tube 18 into the tank through a plurality of inclined jets 54, 56 circumferentially spaced about an end of a vent tube 20 positioned within the tube 18. Each jet is directed toward a central axis 72 of the vent tube, such that the end of vent tube receives gas from the vessel passing between individual jetstreams, which in combination form a conical-shaped barrier to liquid droplets which would otherwise also pass to the vent tube and out the tank 12. Gas is thus vented through the central tube while pressurized liquid flows in an axially opposite direction in the annulus between inner vent tube 20 and the outer liquid tube 18. The system of the present invention is particularly well suited for venting gas from a tank being replenished with liquid at a zero or near zero gravity environment. A screen-type liquid acquisition device 14 employing surface tension is provided for withdrawing substantially liquid from the tank. The withdrawn liquid may be re-supplied to the liquid tube under pressure supplied by circulating pump 24, thereby releasing substantially only gas from the storage tank 12 to reduce pressure in the tank.
