Abstract

A method and apparatus for the physical separation of components from a multi-phase fluid stream into its component phases. More particularly, the invention relates to a housing for a phase separation medium which allows one to change the phase separation medium without the necessity of disconnecting the flow lines. An alternative embodiment of the present invention contemplates a housing incorporating a unique internal valve configuration for controlling and limiting the fluid pressure differential across the sheet of phase-separating material. The internal valve begins to throttle or reduce the fluid flow rate through the sheet of phase-separating material after the differential pressure across the sheet of phase-separating material exceeds a preset value. If throttling the fluid flow rate cannot prevent the differential pressure from exceeding the preset limit, then the internal valve will shut off the fluid flow completely.

Claims

1. A valve comprising a sealing material and a surface actuated to a partially closed or closed position by a force resulting from a differential pressure across opposing sides of a diaphragm wherein the source of differential pressure is the result of a pressure drop across a sheet of phase-separating material.

2. The valve of claim 1 said sheet of phase-separating material forms said diaphragm.

3. The valve of claim 1 wherein said diaphragm is situated in a phase separating housing.

4. The invention of claim 3, wherein said housing comprises:

a. a body having fluid entry and exit ports;

a cavity for receiving a cover, said cavity having an inside diameter, and passages for fluid communication internal to the housing, and

b. a cover having a for receiving and supporting the sheet of phase-separating material, said cover formed to engage said body in fluid impermeable fashion, said cover having an outside diameter.

5. The invention claim 4 wherein there is further provided in said housing an internal fluid passage formed between an outside diameter of the cover and the inside diameter of the cavity within the body.

6. The invention of claim 4 wherein said housing further comprises an inertial tube formed to separate particles from a sample fluid.

7. The invention of claim 6 wherein said cover of said housing engages said body via threaded engagement.

8. The invention of claim 4 wherein said housing further comprises a perforated plate formed to support said phase-separating material.

9. The invention of claim 3, wherein said housing comprises:

a body having a main cavity formed therein;

a cover having first and second ends, said first end of said cover formed to engage said body at said main cavity, said cover having;

a first sample cavity formed in said body, said first sample cavity situated between said first end of said cover and said body, said first sample cavity formed to receive a stream of fluid from said housing; and

a second sample cavity formed in said first end of said cover.

10. The invention of claim 9, wherein said housing has situated therein a fluid permeable support having first and second sides, said first side of said fluid permeable support communicating with said second sample cavity, said second side of said fluid permeable support formed to support said phase separating material;

whereby, upon directing a fluid stream from said housing to said first sample cavity, a portion of said fluid stream passes through phase separation material and said fluid permeable support into said second sample cavity, so as to provide a filtered fluid stream, which filtered fluid stream may be directed out of said body.

11. The invention of claim 10, wherein said phase separating material comprises a filtration medium.

12. The invention of claim 11, wherein said cover and body of said housing are sealed about said first and second sample cavities by an O-ring.

13. The invention of claim 12, wherein said cover of said housing threadingly engages the cavity formed in said body.

14. The invention of claim 11, wherein said body of said housing has formed therein an inlet passage for the flow of unfiltered fluid into said body, said inlet passage having situated therein an inertial tube having first and second ends, said first end of said inertial tube communicating with said inlet passage formed in said body, said second end of said inertial tube situated within a secondary passage, said secondary passage in longitudinal alignment with said inertial tube.

15. The invention of claim 14, wherein said secondary passage has first and second ends, said first end of said secondary passage communicating with a bypass port, said second end of said secondary passage communicating with said first sample cavity.

16. The invention of claim 15, whereby, upon a flow of fluid exiting said second end of said inertial tube, fluid flowing to said second end of said secondary passage abruptly changes direction, providing a degree of inertial pre-separation of particulate matter situated in said fluid.

17. The invention of claim 15, wherein fluids which do not pass through said phase separating material collect in said first sample chamber.

18. The invention of claim 17, wherein there is further provided a drain passage running from said first sample chamber to said bypass port, formed to draining fluids which collect in said first sample chamber.

19. The invention of claim 10, wherein said cover has formed therein a first exit passage for the passing of said filtered fluid stream out of said cover and into said body.

20. The invention of claim 19, wherein said body has formed therein a second exit passage for the passing of said filtered fluid stream from said first exit passage out of said body.

21. The invention of claim 20, wherein said fluid permeable support is formed to be dynamically positionable within said second sample cavity whereby pressure applied to said first side of said fluid permeable support actuates said surface so as to decreases the flow of filtered fluid to said first exit passage.

22. The invention of claim 21, whereby a predetermined pressure applied to said first side of said fluid permeable support actuates said surface to interrupt the flow of filtered fluid to said first exit passage.

23. The invention of claim 22, wherein there is further provided in said valve a biased support pin formed to engage said fluid permeable support.

24. The invention of claim 23, wherein said biased support pin is spring biased.

25. The invention of claim 24, wherein the bias is adjustable.

26. The invention of claim 25, wherein said biased support pin has first and second ends, said first end engaging said second side of said fluid permeable support, said second end of said biased support pin engaging a pin plate, and whereby said spring engages said pin plate.

27. The invention of claim 26, wherein said support pin passes through said first exit passage.

28. The invention of claim 26, wherein there is further provided a fluid impermeable seal situated about said first exit passage in said second sample cavity.

29. The invention of claim 28, wherein said fluid impermeable seal comprises an O-ring.

30. The invention of claim 28, whereby, upon said second side of said fluid permeable support engaging said fluid impermeable seal, flow of filtered fluid to said first exit passage is interrupted.

31. The invention of claim 30, whereby upon said second side of said fluid permeable support dis-engaging said fluid impermeable seal, flow of filtered fluid to said first exit passage resumes.

32. The valve of claim 1 wherein the diaphragm is external to a phase-separating housing.

33. The valve of claim 1 wherein the sealing material is an o-ring.

34. The valve of claim 1 wherein said surface further comprises a support plate for a sheet of phase-separating material.

35. The valve of claim 1 wherein said sealing material and surface are constructed of metal.

36. A valve, comprising:

a sealing material having an underlying, fluid permeable support surface having first and second sides, said first side of said fluid permeable support surface formed to engage a sealing material, said second side formed to support a filtration medium;

biased positioning means for positioning said support surface;

whereby said biased positioning means is calibrated so that a predetermined differential pressure associated with said first and second sides of said support surface engages said bias means to position said first side of said fluid permeable support surface in one of open, partially closed, or closed positions.
