Abstract

Disclosed herein are phase separator devices, and related methods of fabrication and use. The disclosure provides improved phase separator devices for phase separation of input feeds, and systems/methods for utilizing and fabricating the devices. The disclosure provides phase separator devices utilizing inertial separation and porous media extraction for the phase separation of two-phase input feeds (e.g., to separate an input feed of a two-phase mixture to a first phase output (e.g., to a liquid output flow) and to a second phase output (e.g., to a gas output flow)). The device can separate a mixed fluid flow of both liquid and gases. The liquid and gas can include liquid and vapor phases of the same chemical/constituent (e.g., ammonia), or may include liquid and gases of two different constituents (e.g., liquid water and air). The phase separator devices can be utilized at standard gravity to micro-gravity to zero gravity environments.

Claims (41)

1. A phase separator device comprising:

a housing that extends from a first end to a second end, the housing having one or more first openings for the exit of a first phase output and one or more second openings for the exit of a second phase output;

swirl vanes disposed in the housing;

wherein the housing includes an axial flow cyclonic separation section and a porous media section; and

a liquid collection section in the housing; and

wherein the porous media section is a barrier and physically supports a horizontal layer of liquid accumulation of the liquid collection section horizontally on top of the porous media section, the horizontal layer of liquid accumulation of the liquid collection section perpendicular to flow of the second phase output;

wherein the axial flow cyclonic separation section and the porous media section are configured and dimensioned to separate an input feed introduced to the housing into the first phase output and the second phase output;

wherein a pressure drop across the horizontal layer of liquid accumulation and the porous media section prevents the flow of a lower density fluid of the input feed into the one or more first openings as a pressure drop of the one or more second openings is lower than the pressure drop across the horizontal layer of liquid accumulation;

wherein the porous media section is a porous membrane.

2. The phase separator device of claim 1 , wherein the first phase output includes liquid, and the second phase output includes gas.

3. The phase separator device of claim 1 , wherein the input feed is a fluid mixture.

4. The phase separator device of claim 1 , wherein the input feed includes liquid and gases of two different constituents.

5. The phase separator device of claim 1 , wherein the input feed includes liquid and vapor phases of a same constituent.

6. The phase separator device of claim 1 , wherein the input feed introduced to the housing includes ammonia.

7. The phase separator device of claim 1 , wherein the input feed introduced to the housing includes water and air.

8. The phase separator device of claim 1 , wherein the porous media section is fabricated from at least one of porous metal, polymeric membranes, foams, fibrous materials, polymers, ceramics, or glass.

9. A phase separator device comprising:

extractor elements disposed in a housing, the housing having an inlet for an input feed and a first outlet for a first phase output and a second outlet for a second phase output;

wherein each extractor element includes a threaded rod housed in a porous media tube, the threaded rod defining a spiral flow path along the threaded rod, and the porous media tube extending along and housing the entire length of the threaded rod;

wherein the one or more extractor elements are configured and dimensioned to separate the input feed introduced to the inlet into the first phase output and the second phase output;

wherein the input feed follows the spiral flow path of the threaded rod, and inertial energy of flow of the input feed through the spiral flow path provides that: (i) a denser fluid of the input feed moves radially outwards and into contact with the porous media tube and through the porous media tube to the first outlet for the first phase output, and (ii) a lower density fluid of the input feed moves an entire length of the spiral flow path and towards the second outlet for the second phase output;

wherein the first phase output is liquid, and the second phase output is gas; and

wherein a mean pore size of the porous media tube is from 0.1 microns to 100 microns;

wherein the porous media tube is a membrane.

10. A phase separator device comprising:

a housing that extends from a first end to a second end, the housing having one or more first openings for the exit of a first phase output and one or more second openings for the exit of a second phase output;

swirl vanes disposed in the housing;

wherein the housing includes a reverse flow cyclonic separation section and a porous media section; and

a liquid collection section in the housing;

wherein the porous media section is a barrier and physically supports a horizontal layer of liquid accumulation of the liquid collection section horizontally on top of the porous media section, the horizontal layer of liquid accumulation of the liquid collection section perpendicular to flow of the second phase output; and

wherein the reverse flow cyclonic separation section and the porous media section are configured and dimensioned to separate an input feed introduced to the housing into the first phase output and the second phase output;

wherein a pressure drop across the horizontal layer of liquid accumulation and the porous media section prevents the flow of a lower density fluid of the input feed into the one or more first openings as a pressure drop of the one or more second openings is lower than the pressure drop across the horizontal layer of liquid accumulation;

wherein the porous media section is a porous membrane.

11. The phase separator device of claim 10 , wherein the first phase output includes liquid, and the second phase output includes gas.

12. The phase separator device of claim 10 , wherein the input feed is a fluid mixture.

13. The phase separator device of claim 10 , wherein the input feed includes liquid and gases of two different constituents.

14. The phase separator device of claim 10 , wherein the input feed includes liquid and vapor phases of a same constituent.

15. The phase separator device of claim 10 , wherein the input feed introduced to the housing includes ammonia.

16. The phase separator device of claim 10 , wherein the input feed introduced to the housing includes water and air.

17. The phase separator device of claim 10 , wherein the porous media section is fabricated from at least one of porous metal, polymeric membranes, foams, fibrous materials, polymers, ceramics, or glass.

18. The phase separator device of claim 10 , wherein the porous media section horizontally extends across an entire width or diameter of the housing.
