Tank for Separating Liquid from Gas Under Weightless Conditions
First Claim
1. A tank arrangement comprising a liquid separator tank adapted to separate a liquid from a gas, wherein:
- said liquid separator tank comprises a tank vessel having a tank inlet into which a fluid including a liquid, a gas and/or a liquid-gas mixture is to be introduced and having a tank outlet from which pure gas without liquid is to be emitted,a said liquid separator tank further comprises plural liquid storage members that are arranged in said tank vessel and that comprise an open-celled porous metal foam material having pores adapted to take-up the liquid from the fluid, andis all of said metal foam material of all of said liquid storage members has a total pore volume of said pores greater than a volume of the liquid to be taken up.

Abstract
A separator tank for separating and retaining a liquid phase from a liquid-gas fluid mixture is suitable for use with cryogenic as well as non-cryogenic liquids, in space experiments or other applications under weightless conditions. The separator tank has liquid storage members of porous, sponge-like metal foam arranged in a tank vessel. The total pore volume and porosity characteristics of the metal foam are selected to provide capillary uptake greater than the total volume of the liquid to be retained. In a preferred example, the liquid storage members are coaxially arranged, radially spaced, annular cylindrical members, with flow passage notches at alternating opposite ends thereof, to form a meandering fluid flow path therebetween. A gas extraction device is provided at the center of the tank. The separator tank and an upstream connected fluid supply tank can be arranged within a cryostat.

21. A liquid separator tank adapted to separate a liquid from a gas, comprising:
-
a cylindrical tank vessel; a tank inlet near a radially outer perimeter of said tank vessel; a tank outlet near a central axis of said tank vessel; and plural annular cylindrical baffles arranged coaxially in said tank vessel and spaced radially apart from one another, wherein said baffles comprise a metal foam having open-celled pores configured and dimensioned to provide a capillary attraction with respect to the liquid.
