Abstract

A support for a coalescer filter element comprising first and second ends, and a fluid flow bar having at least three fluid channels extending from the first end to the second end; and a filter system including a coalescer filter element arranged on the support, and a method of removing undesirable contaminants and/or fluids from gas using the filter system, are disclosed.

Claims (25)

1 . A support for a coalescer filter element comprising:

(a) a first end including a first end piece, the first end piece having an outer surface and an inner surface, and having a first end annular channel having first and second channel side walls, connected to the inner surface, and having at least three fluid channel openings passing through the outer surface and the inner surface;

(b) a second end including a second end piece, the second end piece having an outer surface and an inner surface, and having a second end annular channel having first and second channel side walls, connected to the inner surface, the second end piece including a hollow fitting having an inlet end, an outlet end, and a side wall having at least two openings through the side wall, the outlet end extending outwardly from the outer surface;

wherein the first end is connected to the second end by a fluid flow bar having at least three fluid channels extending from the first end to the second end, the fluid flow bar and the at least three fluid channels having a longitudinal axis from the first end to the second end, each of the at least three fluid channels having first and second solid side walls, each of the first and second solid side walls each having an inner side and an outer side, the inner side of the first solid wall connected to the inner side of the second solid wall, and the outer side of the first solid wall spaced away from the outer side of the second solid wall, wherein each of the at least three fluid channels separately communicate with a respective fluid channel opening at the first end; and

wherein the hollow fitting and at least two openings are in fluid communication with the at least three fluid channels at the second end.

2 . The support of claim 1 , wherein the hollow fitting has a threaded external surface.

3 . A filtration system comprising:

the support for a coalescer filter element of claim 1 , and a hollow cylindrical coalescer filter element arranged on the support, such that the support passes through the hollow cylindrical coalescer filter element, and one end of the hollow cylindrical coalescer filter element is received in the first end annular channel and another end of the hollow cylindrical coalescer filter element is received in the second end annular channel.

4 . The filtration system of claim 3 , further comprising a fluid receiving container arranged at the outlet end of the hollow fitting in fluid communication with the hollow fitting.

5 . A method for removing undesirable contaminants and/or fluids from gas, the method comprising passing gas through the filtration system of claim 3 , and separating gas from undesirable contaminants and/or fluids.

6 . The method of claim 5 , comprising separating hydrogen from KOH droplets.

7 . A coalescer assembly comprising a housing having a housing outlet and a housing inlet defining a fluid flow path from the housing inlet to the housing outlet and including at least one filtration system in the housing comprising:

a support for a coalescer filter element comprising:

(a) a first end including a first end piece, the first end piece having an outer surface and an inner surface, and having a first end annular channel having first and second channel side walls, connected to the inner surface, and having at least three fluid channel openings passing through the outer surface and the inner surface;

(b) a second end including a second end piece, the second end piece having an outer surface and an inner surface, and having a second end annular channel having first and second channel side walls, connected to the inner surface, the second end piece including a hollow fitting having an inlet end, an outlet end, and a side wall having at least two openings through the side wall, the outlet end extending outwardly from the outer surface;

wherein the first end is connected to the second end by a fluid flow bar having at least three fluid channels extending from the first end to the second end, the fluid flow bar and the at least three fluid channels having a longitudinal axis from the first end to the second end, each of the at least three fluid channels having first and second solid side walls, each of the first and second solid side walls each having an inner side and an outer side, the inner side of the first solid wall connected to the inner side of the second solid wall, and the outer side of the first solid wall spaced away from the outer side of the second solid wall, wherein each of the at least three fluid channels separately communicate with a respective fluid channel opening at the first end; and

wherein the hollow fitting and at least two openings are in fluid communication with the at least three fluid channels at the second end;

the at least one filtration system also including a hollow cylindrical coalescer filter element arranged on the support, such that the support passes through the hollow cylindrical coalescer filter element, and one end of the hollow cylindrical coalescer filter element is received in the first end annular channel and another end of the hollow cylindrical coalescer filter element is received in the second end annular channel; and a fluid receiving container arranged at the outlet end of the hollow fitting in fluid communication with the hollow fitting;

wherein the at least one filtration system is across the fluid flow path.

8 . The coalescer assembly according to claim 7 , including a first filter plate and a second filter plate retaining the at least one filtration system in the housing.

9 . The coalescer assembly according to claim 8 , wherein the first filter plate and the second filter plate retain at least two filtration systems in the housing.

10 . A filtration system comprising:

the support for a coalescer filter element of claim 2 , and

a hollow cylindrical coalescer filter element arranged on the support, such that the support passes through the hollow cylindrical coalescer filter element, and one end of the hollow cylindrical coalescer filter element is received in the first end annular channel and another end of the hollow cylindrical coalescer filter element is received in the second end annular channel.

11 . A method for removing undesirable contaminants and/or fluids from gas, the method comprising passing gas the filtration system of claim 4 , and separating gas from undesirable contaminants and/or fluids.
